How to protect our environment.
Today I read a book.This book about our environments is in danger.
There are air and water on the Earth.
There are people and plants on the Earth.People have lived on the Earth for millions of years.Many years ago,the air was fresh,the water was clean,the sky was blue,animals were happy.Everything was beautiful,everything were nice.But today,everything is different.There air pollution.
Factories in the towns and cities drained waste liquid to the lakes,rivers and seas.Waste gases from cars and factories make the air dirty.People are killing more and more animals.People use their furs to make coats; people use their meat for food.More and more animals are disappearing from the Earth forever.
People are polluting the land,polluting the water,polluting the air!People must stop the pollution.Let’s protect our together!
Everyone should make a contribution to protect the environment.
Taking care of our environment is very important.Wherever you live,you can do something around your neighbourhood.
Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls?Have you ever spat in a public place?Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment.
It is our duty to keep our envionment clean and tidy.You might ask yourself,"Have I ever picked up some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment.
Now I want to say :Let`s do our best to make our world more beautiful!
