Climate change affects water by evaporation increase, which means that since the temperature is getting hotter, polar ice caps, glaciers and basically anything frozen on Earth. This causes the rising of the sea level. What will happen is, people from dry areas would have to migrate for clean water, the cost of water would rise drastically, and without water there would be a huge food shortage. Also, the some parts of the state of Florida will be completely underwater. Even animals will lose their homes! Here is a website that will show you what horrible things can happen if we do not start making a change now.
