It takes a lot less in the way of resources (and produces less greenhouse gas) to grow crops for human consumption than to grow animal feed and raise livestock for meat. Not only do you lose energy on every rung of the food chain (think of how much gets excreted or exhaled as waste while those animals are growing) but it also tends to create a lot of pollutants.
I’m not personally a vegan but agree with the logic of someone who is for environmental purposes.
