The main problem is that the ice is melting because of global warming. People are burning too much fuel. I think we should reduce pollution to save their home. Part 2 Dear humans, wild animals need your help. Please stop cutting down forests and polluting the oceans. You can also support wildlife protection groups. If you help, they will have a chance to survive. Thank you for caring. Part 3 Humans should help wild animals because they are part of our shared planet. If they disappear, the balance of nature will be broken. Protecting them also means protecting our own future. I believe a world with rich wildlife is a healthier and more beautiful world for everyone. 1 学科网（北京）股份有限公司 $
