I wrote this is Geometry, as like so many others. The world as we know it is dying, and man is the cause, we evolved, like any other animal, only we took about our problems differently, with a different thinking to solving problems, and that is what put us here today.
But we have gone to far. What now, we are killing wildlife, which, as we seem to not realize, we cannot live without. Once wildlife is gone, the balance is gone. Everything will crumble.
Now I do not believe this will happen in our lifetime, however, it will happen, and maybe if we weren't so obsessed with the benefits of how we lived, and sacrificed some of the things we "need" the world will balance out.
