Global Warming

The world's own death. Global warming is not allowing much more of us. We are creating the death of our home, at least, so some say. I personally believe that we should be fine, at least in our lifetime, and for a few to come. Global warming is "melting the ice caps so polar bears won't be able to live". Polar bears have enough ice to suffice. It may be raising the water levels, but it won't be enough to cause much damage for a very long time.
