There are dozens, if not hundreds, of projects underway to get plastic out of the ocean. They range from hands-on cleanups of beaches (Canada's effort here is one of the best) to incredibly complex solutions involving fleets of plastic scoopers working in the Great Pacific Garbage Patch. None of them are perfect, all of them will miss a lot, but every one is vital.
As we try to save the world's oceans over the next decades, there is still a place for both old-fashioned hard work, and daring dreams. But the resources we devote to each project will determine what gets done. So...what has the best chance of actually working?
