We live in the world every day. We eat food, drink water, wear clothes, watch TV, use computers and so on. We are producing waste every moment.
We have only one earth. But the environmemt around us is getting worse and worse .In some places . we can’t see fish swimming in the river or trees on the hills. Some people even have no clean water to drink. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living. So there's nothing to keep water from running away. Also we have polluted the land, the river and the air. So we have to face more and more floods and droughts .
