What do you expect it to be,the horizon rises up,the water is all over the planet,the specieses are extinct by then...
There is something we can do now to get us out of the mess like what is going on in the movie [2012].First of all,we make much more money,just in case that the earth indeed is going to be ruined.Second of all,we don't make so much pollution as the people do.So to sum up,we should live neatly,meaningfully and long.
