How do vegans save the earth by eating it.?

By going vegan, we can reduce the impact of climate change, rainforest destruction, and pollution, while saving water and other precious resources. In fact, raising animals for food produces more greenhouse gas emissions than all of the cars, planes, and other forms of transportation combined.  One vegan burger may only use 5% of one animal derived burger, thus protecting valuable resources.  Diminishing the use of agriculture eaten by the livestock (animals), allows us to use much more of the earth, as so much of it is given to farms and animals raised to just be eaten.  I am vegan, and there are many health benefits to being one.  In fact, did you know that vegans often times live up to 7-10 more years than the average animal-by-product-eating person?  Continue to educate yourself widely on this topic, as it is great to explore the crazy facts about veganism, and how some foods are vegan even though you probably never knew (like Oreos)!  Thanks for posting a question and being curious, if you have anymore, I's be happy to answer them!
