Animals are not ours to eat, wear, experiment on, use for entertainment, or abuse in any other way.

Fight Global Warming by Going Vegetarian

Global warming has been called humankind’s “greatest challenge” and the world’s gravest environmental threat. Many conscientious people are trying to help reduce global warming by driving more fuel-efficient cars and using energy-saving light bulbs. Although these measures help, science shows that going vegan is one of the most effective ways to fight global warming. A staggering 51 percent or more of global greenhouse-gas emissions are caused by animal agriculture, according to a report published by the Worldwatch Institute. Additionally, a recent United Nations report concluded that a global shift toward a vegan diet is extremely important in order to combat the worst effects of climate change. According to the United Nations, raising animals for food is “one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global.” In addition, the official handbook for Live Earth, the anti–climate change concerts that Al Gore helped organize, says that not eating meat is the “single most effective thing you can do” to reduce your climate change impact. Carbon dioxide, methane, and nitrous oxide together cause the vast majority of global warming. Raising animals for food is one of the largest sources of carbon dioxide and the single largest source of both methane and nitrous-oxide emissions.

Carbon Dioxide

Burning fossil fuels (such as oil and gasoline) releases carbon dioxide, the primary gas responsible for global warming. Producing one calorie from animal protein requires 11 times as much fossil fuel input—releasing 11 times as much carbon dioxide—as does producing a calorie from plant protein. Feeding massive amounts of grain and water to farmed animals and then killing them and processing, transporting, and storing their flesh is extremely energy-intensive. In addition, enormous amounts of carbon dioxide stored in trees are released during the destruction of vast acres of forest to provide pastureland and to grow crops for farmed animals. On top of this, animal manure also releases large quantities of carbon dioxide.

You could exchange your “regular” car for a hybrid Toyota Prius and, by doing so, prevent about 1 ton of carbon dioxide from entering the atmosphere each year, but according to the University of Chicago, being vegan is more effective in the fight against global warming; a vegan is responsible for the release of approximately 1.5 fewer tons of carbon dioxide into the atmosphere each year than is a meat-eater.

A German study conducted in 2008 concluded that a meat-eater’s diet is responsible for more than seven times as much greenhouse gas emissions as a vegan’s diet. Rajendra Pachauri, the head of the U.N.’s Nobel Prize–winning Intergovernmental Panel on Climate Change (and a vegetarian himself), urges people to “please eat less meat—meat is a very carbon-intensive commodity.”

Methane

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 during digestion and from the acres of cesspools filled with feces that they excrete. Scientists report that every pound of methane is more than 20 times as effective as carbon dioxide is at trapping heat in our atmosphere. The EPA shows that animal agriculture is the single largest source of methane emissions in the U.S.

Nitrous Oxide

Nitrous oxide is about 300 times more potent as a global warming gas than carbon dioxide. According to the U.N., the meat, egg, and dairy industries account for a staggering 65 percent of worldwide nitrous oxide emissions. (Use the N-Calculator to calculate your nitrogen footprint and to see how you could lower your nitrogen usage.)

You Can Help Stop Global Warming!

The most powerful step that we can take as individuals to avert global warming is to stop eating meat, eggs, and dairy products. Order PETA’a free ”Vegetarian/Vegan Starter Kit” and do your part to start saving the planet and animals today!
