1 00:00:05,600 --> 00:00:09,520 Speaker 1: Hyatt's West Kasova. All that smoke drifting across parts of 2 00:00:09,600 --> 00:00:12,720 Speaker 1: the US from Canada's wildfires put us in mind of 3 00:00:12,720 --> 00:00:15,720 Speaker 1: a recent episode we did about the health hazards of 4 00:00:15,920 --> 00:00:19,239 Speaker 1: breathing wildfire smoke. We thought you might want to give 5 00:00:19,280 --> 00:00:22,159 Speaker 1: it a listen. Hope you're having a great weekend, and 6 00:00:22,200 --> 00:00:36,680 Speaker 1: I'll talk to you again on Monday. At the end 7 00:00:36,680 --> 00:00:40,599 Speaker 1: of twenty nineteen and into twenty twenty, massive bushfires ravaged 8 00:00:40,640 --> 00:00:44,199 Speaker 1: Australia in what became known as Black Summer. 9 00:00:44,840 --> 00:00:47,559 Speaker 2: You know, you would look outside at ten o'clock in 10 00:00:47,600 --> 00:00:50,760 Speaker 2: the morning and it would be a black sky and 11 00:00:50,800 --> 00:00:53,040 Speaker 2: the sun, if you could say, the sun would kind 12 00:00:53,040 --> 00:00:56,080 Speaker 2: of be like a red dot. It's just such an 13 00:00:56,160 --> 00:00:57,680 Speaker 2: extreme amount of smoke. 14 00:00:58,640 --> 00:01:01,280 Speaker 1: We hear a lot about the huge, huge economic cost 15 00:01:01,320 --> 00:01:04,800 Speaker 1: of wildfires like this that are growing in frequency and 16 00:01:05,000 --> 00:01:08,920 Speaker 1: size across the globe. Just look at a place like California. 17 00:01:09,040 --> 00:01:13,480 Speaker 1: Homes destroyed, people's lives turned upside down. But the Australia 18 00:01:13,520 --> 00:01:17,480 Speaker 1: disaster is now three years later, awakened officials around the 19 00:01:17,520 --> 00:01:20,559 Speaker 1: world to another toll that's been harder to pin down. 20 00:01:26,400 --> 00:01:29,839 Speaker 1: I'm Westcasova today on the Big Take. Bloomberg reporters Amy 21 00:01:29,880 --> 00:01:34,560 Speaker 1: Bainbridge and Angus Whitley on the elusive health hazards of wildfires, 22 00:01:34,959 --> 00:01:36,120 Speaker 1: especially on children. 23 00:01:45,720 --> 00:01:49,440 Speaker 2: The fires raged across eastern Australia for months on end. 24 00:01:49,760 --> 00:01:55,680 Speaker 2: They generated so much smoke. They engulfed farmland, towns, twenty 25 00:01:55,680 --> 00:01:59,360 Speaker 2: four million hectares of land, the area equivalent to half 26 00:01:59,400 --> 00:02:02,080 Speaker 2: of Californi. Yeah, it was just such a huge event. 27 00:02:02,680 --> 00:02:05,000 Speaker 3: Just the scale of them was something that well most 28 00:02:05,000 --> 00:02:08,640 Speaker 3: of Australia had never experienced before. And also because it 29 00:02:08,720 --> 00:02:11,440 Speaker 3: touched so much of the population. You know, by some 30 00:02:11,600 --> 00:02:14,200 Speaker 3: estermate's eighty percent of the population. That there weren't many 31 00:02:14,280 --> 00:02:17,640 Speaker 3: people who weren't affected, and it really brought something that 32 00:02:18,040 --> 00:02:20,320 Speaker 3: maybe had had in the past, been something that affected 33 00:02:20,400 --> 00:02:23,480 Speaker 3: rural areas of Australia or remote communities. It brought these 34 00:02:23,480 --> 00:02:26,000 Speaker 3: fires into the city. People in the city were suffering 35 00:02:26,040 --> 00:02:29,160 Speaker 3: from smoke effects as well. You know, more than thirty 36 00:02:29,160 --> 00:02:30,440 Speaker 3: people directly died. 37 00:02:30,280 --> 00:02:30,920 Speaker 4: In the fires. 38 00:02:31,760 --> 00:02:34,800 Speaker 3: You know, an estimated four hundred and fifty almost people 39 00:02:34,919 --> 00:02:38,360 Speaker 3: indirectly dying from the fires. It was a tragic season 40 00:02:38,400 --> 00:02:40,040 Speaker 3: that just went on and on and on. 41 00:02:40,160 --> 00:02:42,119 Speaker 4: It was it was awful to live through. 42 00:02:43,080 --> 00:02:45,679 Speaker 3: We wanted to go out and see what the long 43 00:02:45,800 --> 00:02:48,800 Speaker 3: term effects of this far were. And we knew that 44 00:02:48,880 --> 00:02:53,960 Speaker 3: it had devastating consequences in immediate aftermath, but something that 45 00:02:54,080 --> 00:02:57,119 Speaker 3: long and that severe, we thought, well, three years after 46 00:02:57,160 --> 00:02:59,520 Speaker 3: the event, what has that done to people who lived 47 00:02:59,520 --> 00:03:02,640 Speaker 3: through that, particularly what has it done to the kids, 48 00:03:02,880 --> 00:03:04,959 Speaker 3: the really young kids at the time who were breathing 49 00:03:05,000 --> 00:03:07,440 Speaker 3: in that smoke, and also the mothers who are pregnant 50 00:03:07,440 --> 00:03:10,240 Speaker 3: at the time who were breathing in that smoke and 51 00:03:10,440 --> 00:03:14,079 Speaker 3: directly feeding that into their unborn children. So Ema and 52 00:03:14,160 --> 00:03:16,680 Speaker 3: I went at and tried to find the mothers and 53 00:03:16,720 --> 00:03:20,520 Speaker 3: the kids who were affected, and the results were terrifying 54 00:03:20,760 --> 00:03:23,520 Speaker 3: in some respects, and it kind of surprised us what 55 00:03:23,680 --> 00:03:25,519 Speaker 3: the kind of symptoms people were suffering. 56 00:03:27,200 --> 00:03:30,280 Speaker 2: A lot of the women that we spoke to, they're 57 00:03:30,280 --> 00:03:33,600 Speaker 2: still very traumatized. When you talk about that event. At 58 00:03:33,600 --> 00:03:36,440 Speaker 2: the time, a lot of women say now reflecting they 59 00:03:36,480 --> 00:03:39,400 Speaker 2: weren't really equipped to stay out of the smoke to 60 00:03:39,520 --> 00:03:45,080 Speaker 2: try and prevent breathing those toxic particles into their bodies. 61 00:03:45,400 --> 00:03:47,920 Speaker 2: We were told that masks, which of course were all 62 00:03:47,920 --> 00:03:50,560 Speaker 2: now very familiar with you, that the time was so 63 00:03:50,720 --> 00:03:54,120 Speaker 2: hard to access, trying to keep smoke out of your 64 00:03:54,160 --> 00:03:58,520 Speaker 2: house by blocking underdoors with wet towels, putting towels over 65 00:03:58,640 --> 00:04:02,320 Speaker 2: fans and things like that. Just couldn't stop breathing in 66 00:04:02,800 --> 00:04:06,200 Speaker 2: this smoke. And this lasted for weeks and weeks on end, 67 00:04:06,640 --> 00:04:09,000 Speaker 2: and that, of course went to the question the Angus 68 00:04:09,040 --> 00:04:12,240 Speaker 2: and I had was around this acute exposure. What happens 69 00:04:12,240 --> 00:04:14,560 Speaker 2: to your body? What can be the medium and long 70 00:04:14,640 --> 00:04:19,160 Speaker 2: term consequences of breathing in smoke in an event like that. 71 00:04:19,200 --> 00:04:21,560 Speaker 2: And once we started looking around, we realized that there 72 00:04:21,600 --> 00:04:24,760 Speaker 2: was a lot of literature on long term air pollution, 73 00:04:25,240 --> 00:04:28,480 Speaker 2: but there's some emerging research on the impact of breathing 74 00:04:28,480 --> 00:04:31,920 Speaker 2: in wildfire smoke, and that's kind of what we zeroed 75 00:04:31,920 --> 00:04:32,240 Speaker 2: in on. 76 00:04:32,880 --> 00:04:36,680 Speaker 3: What we discovered was that the bush fire or wildfire 77 00:04:36,800 --> 00:04:41,080 Speaker 3: smoke contains hundreds of different ingredients and a lot of 78 00:04:41,400 --> 00:04:44,640 Speaker 3: poisonous gasses. You can imagine it just burns through everything. 79 00:04:44,680 --> 00:04:48,000 Speaker 3: It's not a control blaze burning one particular type of fuel. 80 00:04:48,440 --> 00:04:52,720 Speaker 3: It burns through vehicles, it burns through houses, building materials, 81 00:04:53,279 --> 00:04:55,159 Speaker 3: and the thing that might you know, be toxic in 82 00:04:55,160 --> 00:04:58,400 Speaker 3: the house goes up and smoke as bastos, bricks, concrete. 83 00:04:58,680 --> 00:05:01,320 Speaker 3: There's lots of really top six substances. And what we 84 00:05:01,400 --> 00:05:04,520 Speaker 3: discovered was that doctors and academics are really focused in 85 00:05:04,560 --> 00:05:07,800 Speaker 3: on this tiny particular matter PM two point five in particular, 86 00:05:07,839 --> 00:05:11,960 Speaker 3: which it's full of little pieces of matter which are 87 00:05:12,000 --> 00:05:13,840 Speaker 3: so small that far too small to see with the 88 00:05:13,920 --> 00:05:16,200 Speaker 3: naked eye, of far smaller than the width of a 89 00:05:16,279 --> 00:05:16,840 Speaker 3: human hair. 90 00:05:17,080 --> 00:05:20,440 Speaker 1: And PM two point five is how scientists describe the 91 00:05:20,520 --> 00:05:25,560 Speaker 1: particulate matter in pollution or in wildfire smoke that lodges 92 00:05:25,560 --> 00:05:26,200 Speaker 1: in the lungs. 93 00:05:26,440 --> 00:05:30,520 Speaker 3: That's right, so small it penetrates your lungs, can even 94 00:05:30,640 --> 00:05:32,160 Speaker 3: enter the blood stream, and of course once it's in 95 00:05:32,200 --> 00:05:34,520 Speaker 3: your bloodstream, it can do all sorts of damage to 96 00:05:34,560 --> 00:05:38,240 Speaker 3: different organs. And that's really the matter that does the damage. 97 00:05:38,400 --> 00:05:40,960 Speaker 3: There's PM two point five in ambient air pollution, but 98 00:05:41,240 --> 00:05:43,960 Speaker 3: wildfare smoke is particularly concentrated. 99 00:05:44,520 --> 00:05:47,719 Speaker 1: And what is the difference between wildfire smoke and just 100 00:05:47,880 --> 00:05:48,560 Speaker 1: air pollution. 101 00:05:49,279 --> 00:05:52,200 Speaker 3: Well, ambient air pollution is something that most of the 102 00:05:52,200 --> 00:05:55,040 Speaker 3: world deals with, you know, according to the World Health Organization, 103 00:05:55,320 --> 00:05:59,960 Speaker 3: almost everybody is breathing in some kind of polluted air 104 00:06:00,120 --> 00:06:04,520 Speaker 3: at some point. But wildfast smoke is traditionally very elevated 105 00:06:04,560 --> 00:06:07,160 Speaker 3: for short periods of time at PM two point five 106 00:06:07,240 --> 00:06:10,400 Speaker 3: levels shoot off the scale, and at some point during 107 00:06:10,400 --> 00:06:13,880 Speaker 3: Black Summer and Australia, levels were ten times more than 108 00:06:13,960 --> 00:06:18,320 Speaker 3: safe levels in Australia, so it was very elevated. And 109 00:06:18,640 --> 00:06:21,360 Speaker 3: I think what marked Black Summer at was just the 110 00:06:21,400 --> 00:06:24,320 Speaker 3: longevity of the burning. Usually these things last for a 111 00:06:24,320 --> 00:06:27,719 Speaker 3: few days. Black Summer burned for weeks and weeks and 112 00:06:27,839 --> 00:06:30,520 Speaker 3: nineteen weeks on end in some areas, So I think 113 00:06:30,560 --> 00:06:33,600 Speaker 3: that's what academics and people are really interested in, Well, 114 00:06:33,600 --> 00:06:35,160 Speaker 3: what does that do to the body. You haven't seen 115 00:06:35,160 --> 00:06:37,560 Speaker 3: that kind of duration of polluted air, not in our 116 00:06:37,600 --> 00:06:38,360 Speaker 3: lifetime anyway. 117 00:06:39,920 --> 00:06:43,839 Speaker 2: Fay Johnston, who's kind of like a world renowned researcher 118 00:06:43,920 --> 00:06:47,360 Speaker 2: on wildfire smoke, and she's based in Tasmania, in our 119 00:06:47,440 --> 00:06:50,839 Speaker 2: southern state of Australia, so she's been studying this for 120 00:06:50,960 --> 00:06:53,320 Speaker 2: twenty years and she kind of describes it as like 121 00:06:53,360 --> 00:06:57,520 Speaker 2: this toxic mix of harmful gases including NU grogen dioxide 122 00:06:57,560 --> 00:06:58,640 Speaker 2: carbon monoxide. 123 00:06:58,960 --> 00:07:01,520 Speaker 5: So when I'm talking about particles suspended in the air, 124 00:07:01,560 --> 00:07:03,720 Speaker 5: they can range from great big bits of dust that 125 00:07:03,760 --> 00:07:05,440 Speaker 5: you can see or ash from a. 126 00:07:05,440 --> 00:07:10,440 Speaker 6: Five right down to nanoparticle sized bits of carbon or 127 00:07:10,480 --> 00:07:11,120 Speaker 6: other things. 128 00:07:11,960 --> 00:07:16,400 Speaker 5: The tinier the particle, the more it gets into your system. 129 00:07:16,560 --> 00:07:19,880 Speaker 5: So anything smaller than a size of two and a 130 00:07:19,920 --> 00:07:24,680 Speaker 5: half micrometers. A micrometer is one thousandth of a millimeter, 131 00:07:24,800 --> 00:07:28,040 Speaker 5: so it's really really tiny. Anything smaller than two point 132 00:07:28,080 --> 00:07:32,520 Speaker 5: five will enter into your lungs and can cross into 133 00:07:32,520 --> 00:07:36,120 Speaker 5: your bloodstream or so we often talk about PM two 134 00:07:36,200 --> 00:07:41,320 Speaker 5: point five as one marker of particles, and that's that smaller. 135 00:07:40,960 --> 00:07:44,160 Speaker 6: Size class, and that's the one most studied for health. 136 00:07:45,320 --> 00:07:47,520 Speaker 6: Any kind of combustion will give off a lot of 137 00:07:47,560 --> 00:07:50,400 Speaker 6: particles and a lot of PM two point five. And 138 00:07:50,440 --> 00:07:54,200 Speaker 6: when you're burning wood or bushfires, that kind of we 139 00:07:54,320 --> 00:07:58,600 Speaker 6: call it biomass combustion that generates a lot of PM 140 00:07:58,640 --> 00:08:01,640 Speaker 6: two point five and fast all the size classes. So 141 00:08:01,680 --> 00:08:05,360 Speaker 6: it's a really important source of harmful particles in the air. 142 00:08:05,920 --> 00:08:08,920 Speaker 6: So when you breathe, particles in your body will react 143 00:08:08,920 --> 00:08:12,720 Speaker 6: to it like it reacts to any hazards, and it 144 00:08:12,720 --> 00:08:16,120 Speaker 6: will activate your stress responses and your immune responses, just 145 00:08:16,280 --> 00:08:18,559 Speaker 6: like if you've got pneumonia or if you've got to burn, 146 00:08:18,920 --> 00:08:22,040 Speaker 6: your body reacts to the stress or the threat, and 147 00:08:22,120 --> 00:08:24,640 Speaker 6: it does that in a whole lot of ways. 148 00:08:24,800 --> 00:08:27,680 Speaker 2: And the other thing to think about amongst all this 149 00:08:28,000 --> 00:08:32,240 Speaker 2: is your underlying predisposition, the genetic factors that contribute to 150 00:08:32,280 --> 00:08:34,640 Speaker 2: you as a person, and what this kind of exposure 151 00:08:34,720 --> 00:08:38,280 Speaker 2: might activate in your system, and then therefore what the 152 00:08:38,640 --> 00:08:40,720 Speaker 2: medium and long term consequences might be. 153 00:08:41,120 --> 00:08:44,160 Speaker 3: What Fase told us was that if you are a 154 00:08:44,200 --> 00:08:48,640 Speaker 3: healthy person, maybe you could withstand several days of elevated 155 00:08:48,640 --> 00:08:51,960 Speaker 3: PM two point five, But if you are perhaps just 156 00:08:52,080 --> 00:08:56,360 Speaker 3: susceptible to asthma, the same dose might trigger some long 157 00:08:56,440 --> 00:08:59,240 Speaker 3: term consequences in your own body. So it would have 158 00:08:59,240 --> 00:09:01,880 Speaker 3: different effects to different people, and you mayn't even know 159 00:09:01,960 --> 00:09:04,679 Speaker 3: that you're susceptible to it. Almost in that respect, it's 160 00:09:04,679 --> 00:09:06,880 Speaker 3: a bit of a lottery as to what it might 161 00:09:06,960 --> 00:09:09,680 Speaker 3: do to you. Obviously, if you're already suffering from asthma, 162 00:09:10,160 --> 00:09:12,440 Speaker 3: you're predisposed to it, there's a chance it might affect 163 00:09:12,520 --> 00:09:16,520 Speaker 3: you worse. But there are so many unanswered questions the 164 00:09:16,559 --> 00:09:20,640 Speaker 3: mothers were grappling with. Did the smoke lead directly to 165 00:09:20,840 --> 00:09:24,400 Speaker 3: my child symptoms? Could I have done more? Is there 166 00:09:24,400 --> 00:09:26,760 Speaker 3: a direct link between what I'm seeing in my child 167 00:09:26,800 --> 00:09:30,439 Speaker 3: now and those days where I perhaps breathing in the 168 00:09:30,480 --> 00:09:33,360 Speaker 3: smoke without a mask at the time, and there is 169 00:09:33,400 --> 00:09:36,040 Speaker 3: a hole in the academic research at the moment that 170 00:09:36,280 --> 00:09:40,080 Speaker 3: medics and researchers are racing to fill. 171 00:09:39,200 --> 00:09:41,840 Speaker 1: And you decided to concentrate on children. 172 00:09:41,920 --> 00:09:42,480 Speaker 4: Why is that. 173 00:09:43,320 --> 00:09:46,440 Speaker 2: We were aware that there was quite a major research 174 00:09:46,480 --> 00:09:49,080 Speaker 2: study happening in the state of New South Wales that 175 00:09:49,200 --> 00:09:52,120 Speaker 2: was trying to find out some answers around the medium 176 00:09:52,160 --> 00:09:55,320 Speaker 2: and long term health impacts of black Summer. It's called 177 00:09:55,320 --> 00:09:59,600 Speaker 2: the Mother and Child twenty twenty study, and it's conducted 178 00:09:59,640 --> 00:10:03,680 Speaker 2: by a group of well known, high profile researchers who 179 00:10:04,000 --> 00:10:06,360 Speaker 2: know what they're doing. Basically, we were really interested to 180 00:10:06,360 --> 00:10:08,920 Speaker 2: find out why they wanted to know this. One of 181 00:10:08,960 --> 00:10:11,560 Speaker 2: the first things we did was connect with a general 182 00:10:11,600 --> 00:10:14,760 Speaker 2: practitioner who works in a rural area, runs a very 183 00:10:14,880 --> 00:10:17,880 Speaker 2: large clinic in southern New South Wales northern Victoria, kind 184 00:10:17,880 --> 00:10:20,560 Speaker 2: of in this border region, and she had given evidence 185 00:10:20,600 --> 00:10:24,480 Speaker 2: to a Senate committee hearing about the outcomes of black 186 00:10:24,520 --> 00:10:27,160 Speaker 2: Summer in terms of the smoke inhalation. And we started 187 00:10:27,160 --> 00:10:30,559 Speaker 2: with her and I just remember my first conversation with her, 188 00:10:30,559 --> 00:10:32,360 Speaker 2: and this was towards the end of last year, but 189 00:10:32,440 --> 00:10:34,520 Speaker 2: being kind of blown away by the sorts of things 190 00:10:34,559 --> 00:10:36,960 Speaker 2: she told us she witnessed at the time, and she 191 00:10:37,040 --> 00:10:39,560 Speaker 2: had really grave fears that no one was really doing 192 00:10:39,640 --> 00:10:44,000 Speaker 2: much about what happens when the next emergency invariably comes. 193 00:10:44,600 --> 00:10:47,480 Speaker 1: And that doctor's name is Rebecca mcgow and here she 194 00:10:47,600 --> 00:10:48,240 Speaker 1: is talking to you. 195 00:10:48,920 --> 00:10:52,920 Speaker 7: There was one particular case that really made me sit 196 00:10:53,040 --> 00:10:55,600 Speaker 7: up and start to take notice of this whole issue, 197 00:10:56,040 --> 00:10:59,640 Speaker 7: and it was a woman who baby was born early, 198 00:11:00,120 --> 00:11:05,040 Speaker 7: the baby was born smaller. But what really struck me 199 00:11:05,360 --> 00:11:09,400 Speaker 7: was her comments about her placenta. And she was told 200 00:11:09,640 --> 00:11:13,440 Speaker 7: that her placenta looked like she'd been a smoker, a 201 00:11:13,480 --> 00:11:18,120 Speaker 7: pacadet smoker. And the midwives were all around a circle 202 00:11:18,200 --> 00:11:20,920 Speaker 7: looking at this placenta. They took photos of it, and 203 00:11:20,960 --> 00:11:24,120 Speaker 7: they said, you're a smoker, and she denied it. She said, 204 00:11:24,160 --> 00:11:25,680 Speaker 7: I've never smoked in my life. 205 00:11:25,920 --> 00:11:30,040 Speaker 3: And another mother described her a placenter's being gritty. 206 00:11:30,320 --> 00:11:36,400 Speaker 7: A normal placenta is pink and fleshy, and it looks healthy. 207 00:11:36,800 --> 00:11:40,760 Speaker 7: A disease percenter has a lot of gray in it 208 00:11:41,000 --> 00:11:44,280 Speaker 7: and chalky white bits and parts of it that look 209 00:11:44,280 --> 00:11:47,599 Speaker 7: at what we call friable or a bit fragile, like 210 00:11:47,800 --> 00:11:52,280 Speaker 7: breaking away. The placenta is the most important thing to 211 00:11:52,360 --> 00:11:55,600 Speaker 7: keep the baby growing. So it is the powerhouse, so 212 00:11:55,679 --> 00:11:59,920 Speaker 7: it nourishes the baby. It's the pathway, the portal between 213 00:12:00,080 --> 00:12:03,240 Speaker 7: what the mother breeds in and what she eats, and 214 00:12:03,520 --> 00:12:06,640 Speaker 7: how that all that good nourish medi has passed on 215 00:12:06,720 --> 00:12:10,600 Speaker 7: to the baby Viole, the percenta and the babies we know. 216 00:12:10,760 --> 00:12:13,760 Speaker 3: We also spoke to some doctors at the time, two 217 00:12:13,800 --> 00:12:18,760 Speaker 3: obstetricians who also described similar kind of experiences. But there 218 00:12:18,800 --> 00:12:23,679 Speaker 3: was one particular doctor, Michael Holland, who was a roving 219 00:12:23,720 --> 00:12:28,400 Speaker 3: obstetrician in down south of Sydney, and he described seeing 220 00:12:28,720 --> 00:12:32,320 Speaker 3: three still berths in an era that would ordinarily have 221 00:12:32,720 --> 00:12:36,200 Speaker 3: three hundred berths in a year, and that is very unusual, 222 00:12:36,320 --> 00:12:36,920 Speaker 3: he told us. 223 00:12:37,480 --> 00:12:40,800 Speaker 4: And that's either a coincidence or it's attributed to something. 224 00:12:42,040 --> 00:12:45,280 Speaker 1: After the break, a mother describes the effect she believes 225 00:12:45,280 --> 00:12:47,480 Speaker 1: breathing smoke had on her child. 226 00:12:55,040 --> 00:12:58,320 Speaker 3: There was one boy, Colt, who was the son of 227 00:12:58,480 --> 00:13:01,360 Speaker 3: one woman that we spoke to down in Nulligan, about 228 00:13:01,360 --> 00:13:02,600 Speaker 3: four hours south of Sydney. 229 00:13:03,200 --> 00:13:04,280 Speaker 4: The fires rolled. 230 00:13:04,040 --> 00:13:07,200 Speaker 3: In in early twenty twenty and he's still on breathing 231 00:13:07,240 --> 00:13:08,520 Speaker 3: medication day night. 232 00:13:08,840 --> 00:13:11,920 Speaker 1: And you spoke to Colt's mother, Casey Douglas. 233 00:13:12,280 --> 00:13:16,680 Speaker 8: I just remember I pulled him under my shirt and 234 00:13:15,679 --> 00:13:18,480 Speaker 8: I had him here, and I was trying to just 235 00:13:18,520 --> 00:13:22,440 Speaker 8: shelter him from the smoke. But looking outside at the 236 00:13:22,440 --> 00:13:26,840 Speaker 8: glass windows, the smoke was just in. No matter how 237 00:13:26,920 --> 00:13:29,280 Speaker 8: many all the windows were shut, the smoke was still 238 00:13:29,320 --> 00:13:33,760 Speaker 8: coming in under the door. He was a healthy one 239 00:13:33,840 --> 00:13:39,800 Speaker 8: year old before the smoke, and the smoke was present, 240 00:13:40,400 --> 00:13:44,160 Speaker 8: but Colt didn't get bad until it was so close 241 00:13:44,240 --> 00:13:44,920 Speaker 8: to us. 242 00:13:45,440 --> 00:13:48,920 Speaker 3: There are other kids who perhaps not on regular medication now, 243 00:13:49,000 --> 00:13:52,440 Speaker 3: but had used ventaline or breathing medication at some point 244 00:13:52,520 --> 00:13:56,200 Speaker 3: in the preceding period. It's a medication to help you breathe. 245 00:13:56,400 --> 00:13:59,760 Speaker 3: It's essentially a relaxant. It opens up the airways and 246 00:13:59,800 --> 00:14:03,319 Speaker 3: make it easier to breathe. One of the key subjects 247 00:14:03,360 --> 00:14:06,240 Speaker 3: that we spoke to for our story cult little boy 248 00:14:06,720 --> 00:14:09,600 Speaker 3: who was one at the time, and his mother described 249 00:14:09,600 --> 00:14:11,800 Speaker 3: to us how when he first took it in the 250 00:14:11,880 --> 00:14:15,240 Speaker 3: days after the fire, almost immediately he started to breathe 251 00:14:15,280 --> 00:14:15,880 Speaker 3: more easily. 252 00:14:16,240 --> 00:14:18,800 Speaker 8: No one's quick to link anything to the fires here, 253 00:14:20,040 --> 00:14:23,920 Speaker 8: but yeah, I know in my heart that the breathing 254 00:14:23,960 --> 00:14:28,520 Speaker 8: issues happened straight after the fires, if not during. He's 255 00:14:28,720 --> 00:14:32,440 Speaker 8: now on an asthma plan for his preschool, and he 256 00:14:32,480 --> 00:14:35,000 Speaker 8: has a preventer in the morning and a preventer at night, 257 00:14:35,760 --> 00:14:38,440 Speaker 8: and if he doesn't have that preventer, he has a 258 00:14:38,480 --> 00:14:42,520 Speaker 8: really bad day. And he can hardly run around the 259 00:14:42,520 --> 00:14:48,920 Speaker 8: poor thing without wheezing and being out of breath and puff. 260 00:14:49,040 --> 00:14:53,520 Speaker 8: So it's taken a toll on him for sure. And yeah, 261 00:14:53,920 --> 00:14:57,520 Speaker 8: I feel for him because he'll be most likely on 262 00:14:58,800 --> 00:15:01,000 Speaker 8: vinolin for the rest of his life. 263 00:15:01,320 --> 00:15:05,280 Speaker 3: There was a woman we interviewed in a beautiful coastal 264 00:15:05,320 --> 00:15:08,400 Speaker 3: town called Tura Beach, which is south of Sydney, and 265 00:15:08,600 --> 00:15:12,040 Speaker 3: Amy and I drove down to meet a mother called 266 00:15:12,120 --> 00:15:15,960 Speaker 3: Jen Spears who was worried about her daughter Mia. 267 00:15:16,640 --> 00:15:19,080 Speaker 1: And that's the woman we heard about earlier who believed 268 00:15:19,080 --> 00:15:22,040 Speaker 1: her placenta had been damaged by wildfire smoke. 269 00:15:22,680 --> 00:15:25,240 Speaker 3: We spoke to her in her home and she was 270 00:15:25,360 --> 00:15:28,800 Speaker 3: just reeling off all the specialists in MIA's medical team 271 00:15:28,800 --> 00:15:31,680 Speaker 3: who were attending to her. There was a physiotherapist, there 272 00:15:31,680 --> 00:15:35,160 Speaker 3: was an occupational therapist, there was a speech therapist. There 273 00:15:35,200 --> 00:15:38,360 Speaker 3: was a pediatric neurologist trying to figure out what was 274 00:15:38,400 --> 00:15:42,240 Speaker 3: wrong with me. And Jen had gone through this intense 275 00:15:42,280 --> 00:15:46,640 Speaker 3: period of o smoke exposure she had, as referred to earlier, 276 00:15:46,720 --> 00:15:49,160 Speaker 3: she had gone through this sort of five or six 277 00:15:49,200 --> 00:15:52,680 Speaker 3: week period of intense smoke. She tried escaping to Canberra. 278 00:15:52,840 --> 00:15:55,120 Speaker 3: The smoke was actually worse than camera. She came back 279 00:15:55,120 --> 00:15:58,120 Speaker 3: home and Toura Beach was really one of those places 280 00:15:58,200 --> 00:16:00,840 Speaker 3: that was almost sort of surrounded. It was ambushed, if 281 00:16:00,840 --> 00:16:04,160 Speaker 3: you like, by while far and they didn't see the 282 00:16:04,240 --> 00:16:07,400 Speaker 3: sun for weeks, and there was smoke all over the house. 283 00:16:07,400 --> 00:16:10,160 Speaker 4: And this was when Jen was pregnant with Mia. 284 00:16:10,560 --> 00:16:13,280 Speaker 3: And it should be said that doctors haven't connected MIA's 285 00:16:13,280 --> 00:16:17,600 Speaker 3: symptoms with that smoke exposure, but it's something that preys 286 00:16:17,640 --> 00:16:22,840 Speaker 3: on Jen. And Mia missed her milestones developmental milestone, She 287 00:16:22,960 --> 00:16:26,680 Speaker 3: was slow to eat solids. She was born three weeks 288 00:16:26,720 --> 00:16:30,200 Speaker 3: early because her growth had plateaued in the womb. And 289 00:16:30,280 --> 00:16:34,560 Speaker 3: again according to the midwives, MIA's placenta was partly caulcified. 290 00:16:34,560 --> 00:16:37,560 Speaker 3: It was blackened as if Jen had been a heavy smoker. 291 00:16:37,880 --> 00:16:41,800 Speaker 3: And then subsequently Mia didn't crawl until after her first birthday. 292 00:16:42,560 --> 00:16:43,400 Speaker 4: And she has hip. 293 00:16:43,280 --> 00:16:45,880 Speaker 3: Dysplasia, which is the medical term for a hip socket 294 00:16:45,880 --> 00:16:49,680 Speaker 3: that doesn't fully cover the ball portion of the upper thigh. Bone, 295 00:16:50,080 --> 00:16:55,000 Speaker 3: so really worrying symptoms that doctors haven't yet connected to 296 00:16:55,160 --> 00:16:58,360 Speaker 3: the smoke exposure. But then Jen is wondering, you know, 297 00:16:58,520 --> 00:17:00,960 Speaker 3: was it due to those few weeks of smoke exposure? 298 00:17:01,440 --> 00:17:03,000 Speaker 4: Do we need to do things differently? 299 00:17:03,360 --> 00:17:05,840 Speaker 3: And she said she was talking to us, so no 300 00:17:05,880 --> 00:17:07,800 Speaker 3: one else in her position had to go through the 301 00:17:07,800 --> 00:17:10,679 Speaker 3: same experience again, So it's that gap and knowledge that 302 00:17:10,720 --> 00:17:13,399 Speaker 3: we spoke about earlier that's really sort of weighing on 303 00:17:13,440 --> 00:17:14,760 Speaker 3: these mothers as well. 304 00:17:14,920 --> 00:17:18,679 Speaker 1: Any our doctor is able to draw connections between the 305 00:17:18,680 --> 00:17:21,960 Speaker 1: fires and these sorts of physical ailments that aren't just 306 00:17:22,160 --> 00:17:26,359 Speaker 1: breathing difficulties that you might naturally associate with in ailing smoke. 307 00:17:26,760 --> 00:17:30,600 Speaker 2: We asked this of the general practitioner Rebecca McGowan as well. 308 00:17:30,920 --> 00:17:34,000 Speaker 2: She is part of a number of lobby groups on 309 00:17:34,040 --> 00:17:38,960 Speaker 2: the environment. She said that doctors are often very pushed 310 00:17:39,080 --> 00:17:42,560 Speaker 2: for time and it can be harder to get to 311 00:17:42,640 --> 00:17:46,040 Speaker 2: those bigger picture issues, but she's also confident that there 312 00:17:46,119 --> 00:17:48,520 Speaker 2: is an increasing awareness that there may be a link 313 00:17:48,560 --> 00:17:51,040 Speaker 2: and the only thing that's really going to help with 314 00:17:51,200 --> 00:17:54,240 Speaker 2: this is gathering more data and really putting it firmly 315 00:17:54,280 --> 00:17:57,520 Speaker 2: on the agenda to give practitioners more confidence when they're 316 00:17:57,520 --> 00:17:59,240 Speaker 2: dealing with these kinds of cases. 317 00:18:00,200 --> 00:18:02,760 Speaker 7: Estimated that in Sydney at the height of the black 318 00:18:02,800 --> 00:18:07,920 Speaker 7: summer smoke and fires, that it would be walking around 319 00:18:07,960 --> 00:18:11,199 Speaker 7: Sydney would be equivalent to smoking thirty seven cigarettes in 320 00:18:11,240 --> 00:18:15,159 Speaker 7: one day, and that was actually closer, so closer to 321 00:18:15,160 --> 00:18:17,720 Speaker 7: the fires, it would be more than that. So we 322 00:18:17,880 --> 00:18:20,359 Speaker 7: have that data for the last seventy years on what 323 00:18:20,560 --> 00:18:24,199 Speaker 7: smoking looks like in a woman pregnant woman, so we 324 00:18:24,320 --> 00:18:27,240 Speaker 7: can extrapolate a little bit. We're not just blind blind 325 00:18:27,359 --> 00:18:30,600 Speaker 7: with this. We do have some scientific information. 326 00:18:32,280 --> 00:18:34,960 Speaker 1: What do we know about the wides spread health effects 327 00:18:34,960 --> 00:18:38,160 Speaker 1: of the fires in Australia overall? 328 00:18:38,880 --> 00:18:42,080 Speaker 3: This is the key question. Know we know what it 329 00:18:42,119 --> 00:18:45,800 Speaker 3: did to people at the time. There's good data and 330 00:18:45,840 --> 00:18:51,240 Speaker 3: the media aftermath of higher presentations to emergency departments for 331 00:18:51,640 --> 00:18:59,040 Speaker 3: cardiovascular complaints, for ventiline prescriptions, for breathing difficulties, so all 332 00:18:59,040 --> 00:19:02,520 Speaker 3: that data is immediately available. What we don't know is 333 00:19:02,600 --> 00:19:05,720 Speaker 3: what it's done to people like now three years after 334 00:19:05,760 --> 00:19:08,920 Speaker 3: the event. And as Amy says that Mother and Child 335 00:19:08,920 --> 00:19:09,960 Speaker 3: twenty twenties is. 336 00:19:09,920 --> 00:19:10,680 Speaker 4: A key study. 337 00:19:10,720 --> 00:19:13,120 Speaker 3: But what's also key is that these kind of studies 338 00:19:13,160 --> 00:19:16,840 Speaker 3: go on and on and keep looking at the kids 339 00:19:17,359 --> 00:19:21,040 Speaker 3: as they progress into school through school, and I think 340 00:19:21,040 --> 00:19:23,600 Speaker 3: only then where you get a really good picture of 341 00:19:24,160 --> 00:19:27,400 Speaker 3: what bush farsmoke exposure does to you during your key 342 00:19:27,440 --> 00:19:30,720 Speaker 3: growth period as a child and into adulthood. And there 343 00:19:30,720 --> 00:19:34,240 Speaker 3: are previous studies in the US not particularly focused on 344 00:19:34,320 --> 00:19:38,840 Speaker 3: bush farsmoke, but more on generic air pollution. For instance, 345 00:19:38,840 --> 00:19:42,520 Speaker 3: there was a key study in the US that started 346 00:19:42,640 --> 00:19:46,000 Speaker 3: in the nineteen nineties was a study in the University 347 00:19:46,000 --> 00:19:51,439 Speaker 3: of California that traced a cohort of several thousand kids 348 00:19:51,480 --> 00:19:55,760 Speaker 3: through school in eras that were exposed to air pollution, 349 00:19:56,280 --> 00:20:00,840 Speaker 3: and they found that once a kid reaches eighteen, any 350 00:20:00,920 --> 00:20:03,879 Speaker 3: kind of damage that they've sustained to their lung development 351 00:20:04,119 --> 00:20:07,720 Speaker 3: is really unlikely to be reversed. So there were indicators 352 00:20:07,720 --> 00:20:11,520 Speaker 3: in the past about what generic air pollution does to children, 353 00:20:11,920 --> 00:20:15,920 Speaker 3: but nothing really that pointed to long term effects of 354 00:20:16,320 --> 00:20:17,840 Speaker 3: wildfare smoke in particular. 355 00:20:18,119 --> 00:20:19,879 Speaker 4: I think that's what people are wrestling. 356 00:20:19,520 --> 00:20:23,800 Speaker 3: With now, as wildfires are projected become more common, more severe, 357 00:20:24,160 --> 00:20:29,520 Speaker 3: longer lasting. The wider picture, there are countries that will 358 00:20:29,560 --> 00:20:34,720 Speaker 3: be impacted by wildfire smoke that haven't been impacted wildfire 359 00:20:34,760 --> 00:20:37,679 Speaker 3: smoke to such a degree in the future as the 360 00:20:37,680 --> 00:20:39,560 Speaker 3: climate continues to warm. 361 00:20:40,359 --> 00:20:43,200 Speaker 1: When we come back, what's the plan for a future 362 00:20:43,280 --> 00:20:45,240 Speaker 1: with more wildfires and more smoke. 363 00:20:55,040 --> 00:20:57,879 Speaker 2: We know that meteorologists are warning bushfires are going to 364 00:20:57,880 --> 00:21:01,639 Speaker 2: become more frequent and destructive, and this whole problem is 365 00:21:01,680 --> 00:21:05,359 Speaker 2: just becoming too beg tweet ignore. Already it's costing as 366 00:21:05,440 --> 00:21:08,359 Speaker 2: much as thirty six billion dollars a year in the 367 00:21:08,480 --> 00:21:13,199 Speaker 2: US alone. Meteorologists say that, you know, bushfires, wildfires are 368 00:21:13,240 --> 00:21:16,680 Speaker 2: going to become more frequent and more destructive as temperatures 369 00:21:16,680 --> 00:21:19,040 Speaker 2: continue to rise, and we already know that long term 370 00:21:19,080 --> 00:21:22,080 Speaker 2: health problems are just going to add to that bill. 371 00:21:22,760 --> 00:21:26,239 Speaker 2: And something that people repeatedly raised to us mothers as 372 00:21:26,280 --> 00:21:30,640 Speaker 2: well is the economic productivity that comes out of that too. 373 00:21:30,720 --> 00:21:33,480 Speaker 2: Like women who have to take longer off work to 374 00:21:33,520 --> 00:21:36,080 Speaker 2: care for their children, do they need to spend more 375 00:21:36,080 --> 00:21:39,879 Speaker 2: time helping with developmental delays and things like that, So 376 00:21:40,240 --> 00:21:43,639 Speaker 2: there is some real economic consequences as well. We also 377 00:21:43,760 --> 00:21:47,320 Speaker 2: know that there are places around the world experiencing wildfires 378 00:21:47,320 --> 00:21:51,360 Speaker 2: that have never previously burned because of the changing climate. 379 00:21:51,440 --> 00:21:54,480 Speaker 2: So in many ways, it's putting all communities on their 380 00:21:54,480 --> 00:21:57,960 Speaker 2: toes as they learn about what could potentially lie ahead. 381 00:21:58,520 --> 00:22:02,280 Speaker 3: It was a really good to Nations Environment Program report 382 00:22:02,880 --> 00:22:06,639 Speaker 3: on wildfires, and that pointed to a lot of the 383 00:22:06,640 --> 00:22:09,280 Speaker 3: fires that were burning around the world that we hadn't 384 00:22:09,280 --> 00:22:12,359 Speaker 3: seen before. I think that they said in twenty twenty, 385 00:22:13,119 --> 00:22:16,280 Speaker 3: fires in the Russian Arctic, for instance, burned tens of 386 00:22:16,280 --> 00:22:20,240 Speaker 3: millions of hectors, And they'd been earlier blazes in Alaska, 387 00:22:20,960 --> 00:22:25,320 Speaker 3: in Greenland and Canada, and I think most warrant And 388 00:22:25,320 --> 00:22:29,320 Speaker 3: this was statistic that really struck me was that these 389 00:22:29,400 --> 00:22:32,840 Speaker 3: kind of catastrophes like Black Summer are almost sixty percent 390 00:22:32,920 --> 00:22:36,440 Speaker 3: more likely to happen this century as the climate warns. 391 00:22:36,680 --> 00:22:39,920 Speaker 3: And I think whereas California has experienced eight of its 392 00:22:39,960 --> 00:22:42,840 Speaker 3: ten largest fires on record in just the past five years, 393 00:22:43,160 --> 00:22:46,159 Speaker 3: which might tell you something. And we've had fires in 394 00:22:46,760 --> 00:22:51,520 Speaker 3: suburbs of major cities as well, like Athens Boulder in Colorado. 395 00:22:52,520 --> 00:22:55,800 Speaker 3: So I guess that's the pattern that it's emerging. 396 00:22:56,720 --> 00:23:00,879 Speaker 1: What is Australia doing to try to protect people's health 397 00:23:00,920 --> 00:23:03,560 Speaker 1: the next time around in a way that they couldn't 398 00:23:03,600 --> 00:23:04,600 Speaker 1: anticipate before. 399 00:23:05,520 --> 00:23:09,159 Speaker 3: There was a key inquiry straight after the bush fires 400 00:23:09,160 --> 00:23:13,719 Speaker 3: the Black Summer into what happened, how we could approach 401 00:23:13,760 --> 00:23:17,919 Speaker 3: the next disaster better, and Royal Commission into into the 402 00:23:17,960 --> 00:23:22,639 Speaker 3: Black Summer and that came out with eighty recommendations, including 403 00:23:23,520 --> 00:23:29,080 Speaker 3: improving air quality indication, improving the flow of information to 404 00:23:29,200 --> 00:23:34,359 Speaker 3: people in fire spots, working with the indigenous community to 405 00:23:34,480 --> 00:23:38,240 Speaker 3: work out how to manage the land better. Some of 406 00:23:38,280 --> 00:23:41,160 Speaker 3: those have been actioned, some of them haven't. And certainly 407 00:23:41,160 --> 00:23:45,399 Speaker 3: that there's a better network of air quality monitors they 408 00:23:45,400 --> 00:23:50,680 Speaker 3: were in place, but some of the recommendations that we 409 00:23:50,760 --> 00:23:55,080 Speaker 3: hear from academics and doctors go a bit further, like 410 00:23:56,320 --> 00:24:00,000 Speaker 3: subsidized air purifiers for instance for people who are particularly 411 00:24:00,200 --> 00:24:05,840 Speaker 3: vulnerable for pregnant mothers, good supply of masks for pregnant mothers, 412 00:24:06,320 --> 00:24:11,440 Speaker 3: maybe even evacuation plans for pregnant mothers and vulnerable in kids, 413 00:24:11,480 --> 00:24:13,920 Speaker 3: like putting them at the head of the queue. So 414 00:24:13,960 --> 00:24:17,359 Speaker 3: there are steps that you can take that go further 415 00:24:17,760 --> 00:24:22,320 Speaker 3: than bad information, a better monitoring battle land management, but 416 00:24:22,359 --> 00:24:24,400 Speaker 3: it's not clear that those are being immediately action. 417 00:24:26,320 --> 00:24:31,040 Speaker 1: Our worldwide organizations like the WHO or the UN trying 418 00:24:31,040 --> 00:24:33,639 Speaker 1: to get together to figure out how to get their 419 00:24:33,720 --> 00:24:34,960 Speaker 1: arms around this problem. 420 00:24:35,640 --> 00:24:39,080 Speaker 2: In the next few months, we expect the World Health 421 00:24:39,200 --> 00:24:43,000 Speaker 2: Organization to release a major evidence review of this issue, 422 00:24:43,080 --> 00:24:47,000 Speaker 2: so hopefully bringing together all that we know, and we 423 00:24:47,080 --> 00:24:50,600 Speaker 2: have spoken to doctor Mary Prinicki, who is a scientist 424 00:24:50,640 --> 00:24:53,800 Speaker 2: at Stanford who worked on that evidence review. She has 425 00:24:53,840 --> 00:24:56,320 Speaker 2: said that it's going to make a number of recommendations 426 00:24:56,400 --> 00:24:59,760 Speaker 2: globally for countries, so we do know that there is 427 00:24:59,800 --> 00:25:04,479 Speaker 2: some action on these. We also know more locally here 428 00:25:04,680 --> 00:25:07,040 Speaker 2: that one of the doctors that we interviewed, who has 429 00:25:07,080 --> 00:25:10,160 Speaker 2: since been elected to parliamentary office, is going to put 430 00:25:10,160 --> 00:25:12,720 Speaker 2: smoke related research high on the agenda. He's now the 431 00:25:12,720 --> 00:25:15,920 Speaker 2: Parliamentary Secretary in New South Wales, doctor Michael Hollands. So 432 00:25:16,720 --> 00:25:19,400 Speaker 2: there's things happening globally and there is a push here 433 00:25:19,760 --> 00:25:21,520 Speaker 2: locally as well to try and get a bit of 434 00:25:21,560 --> 00:25:24,720 Speaker 2: traction on this issue and if anything, helped communities prepare 435 00:25:24,760 --> 00:25:27,840 Speaker 2: for the next disaster when it invariably does come. 436 00:25:28,560 --> 00:25:32,280 Speaker 1: Amy Angus, thanks so much for speaking with me today. 437 00:25:32,600 --> 00:25:35,680 Speaker 1: Thank you thanks for listening to us here at the 438 00:25:35,680 --> 00:25:38,880 Speaker 1: Big Take.
