So, do you remember hearing about the guys who said we should build big spaceships that we could fill with landfills and blast them off of Earth? Many people found this idea to be economically inefficient. But, my friend brought up another point courtesy of Mr. Einstein. His findings were that matter can not be created or destroyed, only moved. Therefore, by transferring mass from Earth, what could the the consequences (gravity, etc.) of that be? That caused me to ponder something else. Let's say on arbor day, Joe Treehugger goes out and plants a tree. He did good, right? He took a seed and turned it into a tree? Not really. Nutrients that were below the ground are now above the ground. Nothing innately good was actually created. Matter was merely transformed and rearranged.
