Changing Your Diet Is 'Number One' Way To Help The Planet, Woody Harrelson Says

We can consider believing that only if we assume everyone is privileged enough to have constant access to vegan food. Which is a ridiculous assumption. Being vegan is great and I'm glad people choose to, but you must have a warped view of how others live if you think it's not just possible, but "EASY" to have that diet. Billions of people cannot even afford the luxury of food that isn't the cheapest and most processed food money can buy.
And this is not even addressing your "zero" assertion. Unless you carefully grow and harvest your own crops, all your meals ended up killing and hurting small animals that were attempting to live in a field where your meal was grown.
