Our earth is becoming worse and worse because of serious pollution like land (土地) pollution,water pollution and air pollution.What we did damaged (破坏) our 1 and we meet serious problems now.2 should we humans do to save the earth?
First,we 3 make much rubbish (垃圾).We need more land to deal with rubbish,so there won't be enough 4 for people to live.The land will also be polluted easily and 5 plants can grow.
Next,we should keep the 6 and rivers clean.Fish can't live in the polluted water.If we keep polluting the water,it'll be 7 for us to enjoy so much seafood or swim happily in the sea in the future.
Third,everyone should help keep air clean.Polluted air is bad for our physical health,8 we must think of plans to reduce (减少) air pollution.
To make the earth a better place,we should learn to love our 9 from now on.And everyone should play a part 10 saving the earth.
