Putting this together with the story about the oceans dying [http://www.usatoday.com/story/news/world/2013/10/21/newser-ocean-pollution-overfishing/3143007/], perhaps we could build harvester/mining ships that could trawl the oceans for plastic flotsam/garbage and turn them into 3D printer "ink". Its hard to get people to clean up after themselves, but if there was money in it, people would go after this and it might actually help clean up some of our mess.

It's MOSSAD that has the dirt on them and them by the balls, not the NSA. :-)
