Global warming has been called humankind's “greatest challenge” and the world's most grave environmental threat. Human activities are causing large amounts of “greenhouse gases” (gases that prevent heat from escaping from the Earth's atmosphere) in the atmosphere. This then causes the air around the Earth to become hotter, which scientists say will increasingly lead to catastrophic natural disasters, such as more frequent and intense hurricanes, flooding, and drought. Many people are trying to help reduce global warming by driving more fuel-efficient cars and using less electricity, but by far, the most effective thing that you can do to fight global warming is to go vegetarian.
The billions of chickens, turkeys, pigs, and cows who are crammed into factory farms each year in the U.S. produce enormous amounts of methane, both in their digestive processes and from the feces that they excrete. Scientists report that every molecule of methane is more than 20 times as effective as carbon dioxide is at trapping heat in our atmosphere. Statistics from the Environmental Protection Agency show that animal agriculture is the single largest cause of methane emissions in the U.S. Raising animals for food is causing global warming. ...continued... goveg.com/environment-globalwarming.asp?int=weekly_enews
