In the world there are a lot of problems. But most important it is an environmental problem. If we continue to pollute this world that we will be lost. It seems to me that it is time to stop ecological pollution. In the nature there are a lot of useful plants which help us to live. They give us life. So if we will destroy the nature, to poison air, to use a lot of water, what awaking with us?
I consider that it is necessary to protect ecology!
