Other animals don't raise billions of other animals to cram them into factory farms, deprive them of natural surroundings, pump them full of hormones and antibiotics and then send them off to slaughterhouses to turn them into burgers and other meat products.

Animals live with nature. We don't. We created our own world on top of the natural world, which we are slowly destroying.

We have the brains, skills and resources to maintain and improve our living standards without destroying the natural world. But we choose not to vote with our wallet.

We in the Western world don't need to kill and eat animals anymore to survive. It's purely out of taste pleasure, habit and because 'we have always done it'.

EDIT: watch this video to see the reality of industrial animal farming:
