We have only one earth, so please take. care of it. But the earth is being seriously harmed by human activities. Every day people throw the litter here and there. Every day so much dirty water flows into the river. Every day so many trees are being cut down. Without trees we have no shade. Without drinking water, we can't live even for a day. We have only one earth.Let's take good care of it!
