It is important for us to look after the
Earth well. The Earth gives us a lot of things. 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. Every animal or plant provides food for
other animals or plants. However, animals can't get food from many of the
things that we"give" the Earth. Animals and plants can't cat metal,
plastic or glass. These things will stay in the ground for many, many,
many years.
Some rubbish is very dangerous for plants
and animals. In some places, many animals live together. One animal makes food
for many other animals. If we throw rubbish and chemicals into the water, the
plankton（浮游生物）can die. If there isn't any
plankton, 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.
