ABSTRACT
Some of the barriers to change include things like how eating large quantities of meat become a cultural imperative throughout much of the world, having become a sign of affluence and modernity. Looking just at the livestock "Big Four"—cows, chickens, pigs, and sheep—the average American adult consumed 90 kilograms of meat in 2014, according to data from the Organisation for Economic Co-operation and Development. While levels of omega-6 fatty acids are roughly the same in the meat of corn-fed and grass-fed cattle, levels of omega-3 are higher in the fully pastured cow. The World Health Organization concluded that 50 g of meat a day—that's two small slices of bacon—increases the chance of colorectal cancer by 1 percent. The costs of cheap meat upon the environment are considerable. Shrimp: every kilogram of tropical shrimp caught through trawling the bottom of the ocean comes at the cost of ten kilograms of other marine life that are killed through this process—collateral damage.
