as we know, many great people could succeed just because they did everything big or small earnestly.

preserving natural resources

however, natural resources are not inexhaustible. some reserves are already on the brink of exhaustion and there is no hope of replacing them.

as you know,there's no enough clean water for people. so many of them lose their lives because of water. it's time that we must do something useful to protect our environment. we can plant trees and take good care of them.

we can save the water and ask our parents to do so. we can't throw any litter onto the ground and we should collect them for recycling.

if we take good care of our earth today,it will be more beautiful tomorrow.
