Issue-Polar Bear

Recently, I watched the news about polar bear. The news said that the weather is getting hotter, so the ices of polar thaw quickly. When the polar bears were hibernation, the ices thaw and the bears drop down into the cold water, then the bears are death because they are downed. I think it's very horrible. Because of global warming, the weather get hotter and hotter. We must find some ways to stop it. Or maybe one day when we wake up, we already die because the weather is too hot or too cold.
