What are the best and worst aspects of man's relationship with animals?

Man and animal have always existed nearby. Once upon a time, animals were only food for humans or they themselves were food for wild animals. Then the man tamed the animals. Now many people keep their pets at home and consider them to be their friends. But for wildlife, people do a lot of damage. They destroy the territories inhabited by wild animals. They hunt animals for skin, horns, meat, kill animals that predators eat, or just for fun. Because of humans, many species are endangered. But now people understood their mistakes and started trying to save endangered species. Due to this, now many species have ceased to be considered endangered. Now zoos exist not only to entertain people, but also to save animals.
