Agriculture is a major source of carbon and methane emissions, which in turn are responsible for the general trend of the warming of the planet’s atmosphere and oceans. In fact, agriculture emits more than all of the cars on the roads. 10 percent of the emissions carbon dioxide and methane in the U.S. come from the agricultural sector. Livestock is the biggest source of methane. Cows, for example, emit methane. Methane from a number or sources, including the thawing permafrost, accounted for 30 percent of global warming in 2023. As global population has grown exponentially since the early 1900s, herds of livestock at farms have expanded, at least in the U.S., due to the increasing demand.[1] We are biological animals, and we too must eat. More people means that more food is needed, and the agricultural lobby in the U.S. is not about to let the governments require every resident to become a vegetarian. Indeed, the economic and political power of the large agribusinesses in the U.S. have effectively staved off federal and state regulations regarding emissions. It comes down to population, capitalism, and plutocracy warping democracy.
