Global warming isn't the fictional bogey man many once thought it to be and its effects go way beyond marooning polar bears on melting icebergs. The methane (noisily) produced by livestock is 20 times more deleterious as a greenhouse gas than C02, which makes meat production the second most damaging source of greenhouse gases in the world.
Force-feeding causes the birds' livers to balloon to up to 10 times their normal size and become diseased with what is known as hepatic steatosis. In addition to being miserably ill with a painful and debilitating disease, the geese can barely breathe because their grotesquely enlarged livers displace their lungs and other internal organs... geese can be seen panting constantly in a vain attempt to suck oxygen into their squashed lungs. Veterinarian Holly Cheever has compared what force-fed birds endure in their final days to being smothered.
