I am a vegan and an atheist for animals and the environment. I only care about animals and the environment. ONLY animal lives matter.
The purpose of human life is to make animal lives better and the Earth cleaner.

"A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life merely for the sake of his appetite. And to act so is immoral." — Leo Tolstoy. Writings on Civil Disobedience and Nonviolence (1886).
