WEBVTT - Why Does Eating Meat Consume More Resources Than Eating Plants?

0:00:01.920 --> 0:00:06.600
<v Speaker 1>Welcome to brain Stuff production of I Heart Radio. Hey

0:00:06.720 --> 0:00:11.280
<v Speaker 1>brain Stuff, Lauren Vogelbaum here. Over the past couple decades,

0:00:11.400 --> 0:00:14.360
<v Speaker 1>and perhaps especially over the past couple of years, there's

0:00:14.400 --> 0:00:18.320
<v Speaker 1>been increasing attention to and hype around plant based eating.

0:00:19.160 --> 0:00:22.040
<v Speaker 1>People may avoid or cut back on animal products for

0:00:22.120 --> 0:00:25.319
<v Speaker 1>all kinds of reasons, from ethics to religion to the

0:00:25.520 --> 0:00:28.720
<v Speaker 1>fad diet of the moment. But today we're focusing on

0:00:28.760 --> 0:00:31.920
<v Speaker 1>a different and perhaps more scientific or at least data

0:00:32.000 --> 0:00:36.880
<v Speaker 1>driven angle the environment. Production of the meat we eat

0:00:37.000 --> 0:00:40.960
<v Speaker 1>burns up a lot of natural resources. For example, according

0:00:41.000 --> 0:00:44.479
<v Speaker 1>to the Center for a Livable Future at Johns Hopkins University,

0:00:44.680 --> 0:00:46.720
<v Speaker 1>it can take as much as six hundred and twenty

0:00:46.720 --> 0:00:50.200
<v Speaker 1>five gallons that's some two thou fifty liters of water

0:00:50.520 --> 0:00:53.360
<v Speaker 1>to produce a quarter pounder. When you've take into account

0:00:53.400 --> 0:00:55.800
<v Speaker 1>not just the water that cattle drink, but the irrigation

0:00:55.920 --> 0:00:58.360
<v Speaker 1>required to produce the grain and grasses that they ate.

0:00:59.280 --> 0:01:02.920
<v Speaker 1>Research by scientists shows that raising farm animals accounts for

0:01:04.120 --> 0:01:08.840
<v Speaker 1>of the world's freshwater consumption. Pound for pound, The animals

0:01:08.840 --> 0:01:11.440
<v Speaker 1>we eat require a lot more resources to grow than

0:01:11.480 --> 0:01:13.800
<v Speaker 1>the plants we eat. But when you factor in the

0:01:13.840 --> 0:01:17.200
<v Speaker 1>amount that a cow ate before it became your burger. Omnivores,

0:01:17.480 --> 0:01:19.760
<v Speaker 1>that is, those of us who consume both plant and

0:01:19.840 --> 0:01:24.640
<v Speaker 1>animal products consume more plant based food than vegetarians or vegans.

0:01:26.319 --> 0:01:31.000
<v Speaker 1>The study Patterns of Food Consumption among Vegetarians and non Vegetarians,

0:01:31.000 --> 0:01:35.480
<v Speaker 1>published in the Journal of Nutrition, surveyed eighty nine thousand

0:01:35.480 --> 0:01:38.120
<v Speaker 1>people in the US and Canada to gather data on

0:01:38.280 --> 0:01:43.279
<v Speaker 1>various dietary preferences. These subjects ranged from people who ate meat, eggs,

0:01:43.319 --> 0:01:46.839
<v Speaker 1>and dairy products to hardcore vegans who avoid any food

0:01:46.880 --> 0:01:49.760
<v Speaker 1>that comes from an animal. In between, there are lacto

0:01:49.800 --> 0:01:53.400
<v Speaker 1>oval vegetarians who consume dairy products and eat eggs, pasco

0:01:53.560 --> 0:01:56.400
<v Speaker 1>vegetarians who eat fish but no red meat or poultry,

0:01:56.720 --> 0:02:02.280
<v Speaker 1>and semi vegetarians who eat meat occasionally. The researchers tallied

0:02:02.360 --> 0:02:04.480
<v Speaker 1>up the total weight of the plant based foods that

0:02:04.520 --> 0:02:11.120
<v Speaker 1>the subjects ate every day, that is, fruits, vegetables, avocados, potatoes, grains, lagoons, soy, nuts,

0:02:11.120 --> 0:02:14.800
<v Speaker 1>and seeds. And now I'm rounding the numbers here for

0:02:15.000 --> 0:02:19.000
<v Speaker 1>audio simplicity, but they found that vegans, on average ate

0:02:19.040 --> 0:02:22.800
<v Speaker 1>about seventeen hundred grams that's sixty ounces of plant based

0:02:22.800 --> 0:02:27.120
<v Speaker 1>foods a lacto ova vegetarians and pesco vegetarians each ate

0:02:27.160 --> 0:02:31.919
<v Speaker 1>about fourteen hundred grams that's fifty ounces. Omnivores, in comparison,

0:02:32.320 --> 0:02:35.000
<v Speaker 1>ate about eleven hundred grams or forty ounces of plant

0:02:35.000 --> 0:02:37.800
<v Speaker 1>based foods, not as much on its own as the vegetarians,

0:02:37.880 --> 0:02:42.440
<v Speaker 1>but a substantial amount. However, the omnivores in the study

0:02:42.639 --> 0:02:46.000
<v Speaker 1>also ate about sixty grams or two ounces of meat

0:02:46.080 --> 0:02:49.200
<v Speaker 1>a day. That's actually a lot lower than the national

0:02:49.240 --> 0:02:51.760
<v Speaker 1>meat eating average of around two hundred and twenty five

0:02:51.800 --> 0:02:55.440
<v Speaker 1>grams or eight ounces based on US Department of Agriculture data,

0:02:55.919 --> 0:02:58.400
<v Speaker 1>but let's assume the smaller amount for now. As we

0:02:58.440 --> 0:03:01.840
<v Speaker 1>consider the amount of grain grasses consumed by the animals

0:03:01.840 --> 0:03:05.040
<v Speaker 1>that end up as meat on our plates, this gets

0:03:05.040 --> 0:03:08.400
<v Speaker 1>a little trickier to calculate, because, of course, different animals

0:03:08.400 --> 0:03:12.359
<v Speaker 1>consume different amounts of plant based food. For the article,

0:03:12.360 --> 0:03:14.680
<v Speaker 1>this episode is based on How Stuff Works. Spoke by

0:03:14.760 --> 0:03:18.000
<v Speaker 1>email with Marion Nestley, the PAULA. Goddard Professor in the

0:03:18.040 --> 0:03:20.520
<v Speaker 1>Department of Nutrition, Food Studies, and Public Health at New

0:03:20.600 --> 0:03:24.520
<v Speaker 1>York University and author of the book Food Politics. She

0:03:24.600 --> 0:03:27.160
<v Speaker 1>said the ratio seems to be on the order of

0:03:27.240 --> 0:03:31.600
<v Speaker 1>six pounds of grain to one pound of meat. So

0:03:31.800 --> 0:03:34.680
<v Speaker 1>even that low sixty grams or two ounces of meat

0:03:35.040 --> 0:03:37.960
<v Speaker 1>represents the equivalent of an extra three hundred and sixty

0:03:37.960 --> 0:03:41.320
<v Speaker 1>grams or twelve ounces of grain based intake every day,

0:03:41.720 --> 0:03:45.320
<v Speaker 1>meaning the omnivore study participants were responsible for consuming a

0:03:45.360 --> 0:03:49.720
<v Speaker 1>bit more plants than their vegetarian counterparts. But again, remember

0:03:49.920 --> 0:03:52.640
<v Speaker 1>that's using an example at the low end of meat eating.

0:03:53.240 --> 0:03:55.600
<v Speaker 1>If you use the U s d A's daily average

0:03:55.600 --> 0:03:57.960
<v Speaker 1>of two hundred and twenty five grams or eight ounces

0:03:57.960 --> 0:04:00.840
<v Speaker 1>of meat consumption, the total soul is to round about

0:04:00.840 --> 0:04:05.080
<v Speaker 1>twenty grams or ninety ounces of plant based food. That's

0:04:05.200 --> 0:04:08.920
<v Speaker 1>way more than even vegans consume about fifty or half

0:04:08.960 --> 0:04:14.160
<v Speaker 1>again as much. So why is this significant. The amount

0:04:14.200 --> 0:04:17.799
<v Speaker 1>of plant based food that meat animals consume is mind boggling.

0:04:18.400 --> 0:04:22.520
<v Speaker 1>As Nestlie points out, roughly se of coin and soybean production,

0:04:22.680 --> 0:04:26.320
<v Speaker 1>just for example, goes to feed animals. That makes meat

0:04:26.320 --> 0:04:29.200
<v Speaker 1>production an inefficient way to glean nutrition out of the

0:04:29.200 --> 0:04:34.560
<v Speaker 1>planet's farmland. Study by University of Minnesota researchers published in

0:04:34.600 --> 0:04:38.280
<v Speaker 1>the journal Environmental Research Letters concluded that if the farmland

0:04:38.320 --> 0:04:41.200
<v Speaker 1>needed to produce animal feed. Were instead used to grow

0:04:41.240 --> 0:04:44.520
<v Speaker 1>food for human consumption, we could feed an additional four

0:04:44.640 --> 0:04:53.400
<v Speaker 1>billion people worldwide. Today's episode is based on the article

0:04:53.560 --> 0:04:56.159
<v Speaker 1>far more plants get consumed thanks to meat eaters, not
