Stick a fork in it

Don't worry about the suburban sprawl you see being built on former farmland... it'll all come crashing to a halt soon enough... just read what James Howard Kunstler has to say about it:

My view is that the suburban project, per se, in the United States is over, finished. Like, totally. You can stick a fork in it.

He's got the most focused and realistic view of the future of the US as it relates to land usage of anyone I've read. You'll hate what he has to say at first, but then you'll go "oh shit.. he's right!".
