Endangered animals

I have read a book called endangered animals.I say it is pretty sad to read it and it says this many animals have been  hurt or killed by people. I want to save them by not killing them. I don't like how there is this many animals left in the world. Only because i love animals and i bet you half of the world does to. Also what are we going to do if your favorite animal is endangered or is coming to become a endangered by those people killing or hurting them. I would feel bad and sad.
