There is nothing wrong with the natural world and never has been, how could there be? There is no bench mark to measure it against. Life simply does what it has to in order to survive. It is a cruel organic world where all matter is recycled including living animals. This involves larger creatures devouring smaller creatures often while still alive. It has always been thus.
Humans have created an artificial world that despite its benefits is not without its problems. It's convenient for humans to pretend that an invisible god is responsible for all the good and the bad in the world. Instead of humans seeking a solution to the world’s problems from their various gods they need to realize that they are the world’s problem.
Forgive me but it's Friday and throwing my coin in the ring makes me feel alive!
