the world 20 years from now

I think the world 20 years from now we will be under water lik the lost city of atlantes. It will be really cool because we will all grow gills. We will also grow a drsol fin so we will blend in with the dolphins. We will build houses out of water so that will be also really cool. That is what i think what will happen in 20 years. I am not 100% sure about that but it would be cool.
