We have only a few years left, at best, to make radical changes to save ourselves from ecological meltdown. A person who is vegan will save 1,100 gallons of water, 20 pounds CO2 equivalent, 30 square feet of forested land, 45 pounds of grain, and one sentient animal’s life13 every day. We do not, given what lies ahead of us, have any other option.
If you need a clear, succinct, well-referenced summary that lays out the key environmental reasons to go vegan read this article – Saving the Planet, One Meal at a Time (9 November, 2014) by Chris Hedges.
If you claim to care about the environment, then going vegan is not an option. If you want to argue this position read Hedges’ article first, then we can talk. [The list of linked references at the end of the article are also worth reading.]
A vegan world will not solve all our problems, but it will give us a chance and more importantly time to sort the rest of it out.
