One of the biggest problems facing the world is Global warming and its effects. Many scientists believe that Global warming is caused by human activity. In this essay I will talk about this problem and the causes and solutions of Global warming.
One of the biggest problems caused by warming is melting ice shelves, which is could also affect in rising sea levels and flooding coastal areas. Another result of Global warming is change in weather patterns. This might have stronger and more frequent storms. Finally, warmer weather could also effect and changing migration patterns, and many risk higher extinction. This might have move mosquitoes and their disease, which also increased air pollution and caused typhoons and tornados.
In my opinion, we have to reduce fossil fuel. This will increased use of alternative energy sources, including solar energy and wind power. And planting more trees.
