Used Food...Yum!

As we may know, humans are a wasteful species. We throw away tons and tons of stuff every year ranging from foods to consumer products to even large things like a car or a building. Think about the left overs from your dinner plate that you toss away while there are people on the other side of the world or even next door to your house would die to have your left overs. It's a waste to throw things away so think of your pocket change, would you throw away all of your coins? Likely not because when you start adding them all up you can end up with a whole lot more than just a few coins right? So why stop at collecting your coins? There's a ton of other stuff that you can bundle up and save but when is it just going too far? Too taboo? It reminds of a person on Yahoo Answers asking for some insight on his idea of gathering all the left over food at the mall's foodcourt and bringing them home to eat later which is a good idea in theory because there are a ton of food tossed away by consumers at the mall but even you don't see bums doing that in the mall so why should you? Is it right to stoop even lower than a bum? Even if he did cut off the bitten portions, you never know what people did to their food. They probably dropped their fleas in their salad or something. What's the limit to being resourceful?
