A subject that has been in the spotlight over the past few years is ecology. People are always saying that we have to change our habits in order to avoid destroying the environment. I think the environment is something perfect and it can't be destroyed by us. It is always balanced. Species have been missing since before humans. In my opinion, the problem is that when humans start to interfere so much in the environment balance, the environment has to kill humans in order to keep itself balanced.
