A new study published in Science found that ditching animal products can reduce your carbon footprint by up to 73%.

This study is one of the most comprehensive to date. Researchers at the University of Oxford analyzed the detrimental environmental effects of animal agriculture, looking at data from nearly 40,000 factory farms in 119 countries.

The study found that if everyone went vegan, global land use could be reduced by 75%.

"This would be comparable to the size of the United States, China, Australia, and the whole European Union combined," says Mercy for Animals.

In addition, the study confirmed that a vegan world would save an incredible number of wildlife, whose loss of habitat to factory farming is a major threat to their existence.

"A recent report from Farm Animal Investment Risk and Return found that the meat industry is jeopardizing the Paris climate agreement by failing to properly report its emissions, despite being the single largest contributor to climate change," says MFA.

"Raising animals for food produces more greenhouse gas emissions than all the cars, planes, and other forms of transportation combined."

According to the Food and Agriculture Organization of the United Nations, carbon dioxide emissions from animal agriculture make up about 15% of global human-induced emissions. This means that even without burning fossil fuels, we will exceed our 565-gigaton CO2e limit by 2030.

Vegan alternatives to meat, dairy, and eggs require a mere fraction of the resources to produce. As study after study exposes the harmful effects of animal agriculture, it has become clear that a vegan future may be our only future.
