Trinity Rescue Kit just donated 500$ of your donations to the Ocean Cleanup project, which aims on cleaning up the ocean of ALL plastic within 5 years and make some money of it doing so. I believe science with an economical benefit is the ONLY solution to saving the planet and mankind. The idea you had about cleaning up the ocean from plastic debris with large booms is basically what I've been thinking about as well for years. I'm just not an engineer who could work out such an idea. People, the pollution of our seas might be the biggest problem our planet might face. If the oceans are dead, our biggest supplier of oxygen and co² conversion gets lost (plankton accounts for most co² conversion in the world). The oceans are even more important than the rainforests. So if you can, make a donation or at least share and like the project.
