In the future?

Has anyone wondered what the world would look/be like in 30-40 years time? 

In my opinion two things could happen (1) the world would have a lot more pollution and there could be a lot more plastic in the our oceans, animals could go extincted. 

Or number 2 

 (2) the world will be more evolved there will be flying cars and houses might be in the sky clothes would look pretty weird to!
