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