aticle about Polar Bears Extinction.

During all these years global warming has been increasing. The glaciers are melting and there's not place where Polar Bears can live. Global warming could cause polar bears to go extinct by the end of the century by decreasing the sea ice that sustains them. This is a really sad situation because these years would be the last ones we see them alive. The ice has broken up earlier and earlier in the year over the past few decades. I think in the next 30 years there's not going to be more polar bears because of our fault. Polar bears are disappearing from the earth, because we're destroying their habitat. How do we destroy their habitat? we destroy their habitat when we use our cars , factories, because the smoke they produce affect the atmosphere and that's global warming is produced, and that's how we destroy their habitat.
