what do you think the wold will be look like in 20 years?

what do you think the world will be look like in 20 years ?I am thinking this question now.i think ,now the weather is sunny,the sky is so blue.,maybe 20years later ,the sky is black ,if we still pollution the environment.today ,the wind is blowing very soft and gently.20years later ,the wind will be a gost ,everyday blows loudly and screams terribly!,if we still pollution the environment.and there will be many things we can't expect.so please love the earth and then it will love us too.
