So no more gases destroying our environment, agriculture is responsible for an estimated 14% of the world’s greenhouse gases. A significant portion of these emissions come from methane, which, in terms of its contribution to global warming, is 23 times more powerful than carbon dioxide. The U.S. Food and Agriculture Organization says that agricultural methane output could increase by 60 percent by 2030. The world’s 1.5 billion cows and billions of other grazing animals emit dozens of polluting gases, including lots of methane. Two-thirds of all ammonia comes from cows. /wow/ Here is a solution, and or give up meat, I prefer the latter.
