In the past years,our earth is a beautiful planet.There were many different plants grew peacefully,and animals lived happily.
But since human beings began to appear,the environment was getting worse and worse.We cut down trees to make houses at first.That's nothing.But as our lives were be coming better,we detroyed our home-----the earth , more.We threw rubbish everywhere and polluted the ground or the sea.We put the petrol which we produce hard into the sea and it pullutes the sea.
When these are happening ,the animals have no homes to live.So they will die soon.So do people.
For all ,please everyone stop breaking our home----the earth.It is really neccesary for all of us to protect our home for our future and leave the blue sky and green lands for our descendants.本回答被网友采纳
