We all know that we need water to live. Up to 75% of our bodies is water and we need to drink water every day to be healthy! So what will happen to the Earth’s water if global warming （全球变暖）gets worse?
About 71% of the Earth’s surface is covered with water. When the temperature of the Earth rises, the temperature of the water rises, too. Higher water temperatures will kill the underwater plants and tiny fish. But it’s not just the fish! Higher temperatures also have an influence on animals on land. Some scientists think that because of global warming, two thirds of the world’s polar bears will never be seen on our planet by 2050.
Global warming makes the weather change, too. In some places, there will be less rain. This will cause deserts to be larger. In other places, the rain will become very strong and heavy, so we will have less farmland and not enough food for humans.
Global warming is a big problem. But we can help by making small changes like turning off the water, lights, and TV when we aren’t using them!
