I believe that global warming is one of the major most serious problems of the world. When you hear about global warming most people may think what is the big deal it is just causing ice caps to melt, but they are not fully aware of the dangerous horrible affects that it can have. Global warming is so bad it can even cause sickness and disease. Some people may think it is made up or it isn't really going to affect them but if we want to stop global warming we need to wake up and start now! If the world does not contribute to stop global warming there will be things such as famine and drought and even extinction in species like plants and animals.
