Dumping sites?

Question:approximately how much land is needed to dump garbage in the U.S.?

PLease and thank you.

Answers:
Evidently all of it, considering there is trash everywhere.
But is it really trash?

There is a commercial on myspace about garbage picking, everyone should try it.

The other day I was on a walk/bike path near my house in a nice neighborhood and there was a white leather chair in perfect condition sitting out next to the trash can, I wish I had a truck!
