A world where everyone is vegan is a world where world war 3 will happen killing many animals in more horrific ways and causing mass extinction and it's not anywhere close to achievable with the shear amount of extra plant based food we would need to grow annually. Fuck these guys, they are better off promoting the use of condoms so we have less mouths to feed. Idealist with only complaints but no plan past their whining.
That doesn't make any sense. Animal products take up way more space than vegtables, both directly and indirectly (most of the plants we grow are to feed the animals). If everyone were to go vegan, we would actually save huge amounts of space (and also effort, water...), so it's very achievable.
