earth 20 years from now

I think this planet is going to explode in 20 years. No i am just kidding. What i really think about the earth 2o years from now is i think there will be a lot of buildings around. What i mean by that is there will be not as much land. I also think we are going to have to ride bikes, instead of cars because the gas prices will be so high. And that is what i think about the earth 20 years from now.
