From reading the article “Humanity has wiped out 60% of animal populations since 1970, report finds”, there’s a quote said, “Humanity has wiped out 60% of mammals, birds, fish and reptiles since 1970, leading the world’s foremost experts to warn that the annihilation of wildlife is now an emergency that threatens civilisation”, it means the world is loosing animals, they are in a low population. I think it’s impossible if the world would live without animals. If the world only have human beings, we would have no other living things to survive. It’s horrible idea to live without animals, loosing nature is killing us in another way. As human beings, we should all realize this is a big problem to our life.
