The population of the Earth is growing fast. It is important that we look after the Earth. We need it.
1 . We also give the Earth a lot, but some of the things are not good.
In nature, when something dies, other animals and plants get food from it. 2 . However, animals can’t get food from many of the things that we “give” the Earth. Animals and plants can’t eat metal (金属), plastic (塑料) and glass. These things will stay in the ground for many, many years.
Some rubbish (垃圾) is very dangerous for plants and animals. 3, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals (化学物) in the water, the plankton (浮游生物) can die. 4 , many animals have nothing to eat.
So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!
