Beef and climate change. Fact-checking 'What I've Learned"'s video on red meat and climate change, climate science evidence on meat, esp. beef, and environmental impactWhat I’ve learned: beef isnt that pollutingraising animals= greenhouse emissions. growing their food = more emissions. eliminating animal agriculture reduces greenhouse emissions GHGs by 2.6%?stop raising animals BUT keep growing tons of corn even tho cows and pigs and chickens are gonegrow tons of corn. our diet = 80% grains, mostly corneven with these crops =better for environment, less emissionsif we keep producing animal food emissions don’t change as muchfarmers would stop growing food for cows? continue to grow animal feed?Feedlot diet: plant-based scenario= 5,000 cals3,000cals from corn (24 ears of corn)if farmers didn’t change, kept putting out corn? (assuming crops in proportions currently grown)no animals but produce their food? environmental improvement = not largeworth moderating animal agriculture? animal agriculture esp. beef, corn in monoculture, generates less emissionsno animal products = lower food GHG emissionsUS meat = 3x the global average, dietary change has greater effect, reducing food emissions by 61-73%”we eat more beef, change our dietno animal products: “28% reduction in global greenhouse gas emissions”. emissions from food in half, total emissions down by 28%50% reduction in animal products = 20% less emissionsanimal products = majority of food-related emissions (70% of agricultural emissions). “meat dominates impacts on emissions”moderating animal foods. reducing food waste cuts food emissions by 9%, changing diet, moderating animal foods, 56% less emissions from foodtotal emissions? GHG emissions require diet change less animal products, esp. beef= effective to reduce dietary emissionsno Animal Agriculture = 56% less Emissionsless emissions: cattle to pigs/chicken. more impact than plants, less than red meatred meat? do environmental scientists hate beef? environmental impact is disproportionateemissions for plant foods. bigger emissions: eggs, dairy, fish, chicken, pork, beef. higher than other animal productsmeat (beef or lamb) = environmental impact 20–100 times plants. animal products = 2–25x higher than plants. whether foods are matched by protein content, serving, or massbeef requires more feed. 1lb of milk or eggs = 2-3lbs of plants, poultry = 2-5, pork 3-9, beef = 24-49less cows = less cropsfeeding cows grass: environment. grass-fed beef requires more water, more fossil fuels, bigger carbon footprint (emissions extend)ruminants convert grass into human-edible protein, big environmental impactis all beef the same? some producers cause more emissions. even cleanest beef = worse than animal foods and much worse than plant protein like beansdietary change (foods we eat)=more benefits than tweaking productionoptimizing beeffossil fuels? can we cut fossil fuels and leave food alone? reducing emissions from fossil fuels is essential but even if fossil fuel emissions were halted, food would prevent climate targetsclimate goals require changes to food system. eliminate fossil fuels = more leeway on foodchanges to transportation + energy + Food (big chunk of emissions)many don’t want to change fossil fuelsare animals/beef a significant source of emissions? yes. will it solve climate change by itself? noConnect with me:Facebook: https://www.facebook.com/DrGilCarvalho/Twitter: https://twitter.com/NutritionMadeS3Animations: Even Topland @toplandmediaReferences:https://www.pnas.org/content/pnas/114/48/E10301.full.pdfhttps://www.pnas.org/content/115/8/E1701https://www.pnas.org/content/115/8/E1703https://www.pnas.org/content/115/8/E1704https://fdc.nal.usda.gov/fdc-app.html#/food-details/168400/nutrientshttps://www.pnas.org/content/115/8/E1706https://fdc.nal Learn more about your ad choices.
