My biggest worry about the enviroment

My biggest worry about the environment is global warming. The polar bears are dieing because of it. The climate is changing and the polar bears cannot find any food for their young. Polar bears will soon become extinct.Please help the polar bears. My favorite animal is the polar bear and I will try to help them as much as I can. I hope that you will help them too. Their is another animal that is living in cold climate and that is the penguin. So please please please help these animals from becoming extinct. Tell your family about it too. They might want to help us to save these wonderful animals.
