Tending/rewilding our waterways and oceans

By now, I’m sure a lot of you have heard about the water crisis in Ohio. http://www.theguardian.com/world/2014/aug/03/toledo-water-pollution-farming-practices-lake-erie-phosphorus

Permaculture, habitat restoration, and other indigenous land management techniques can go a long way in healing rivers and creeks as well as land. Dismantling car culture could help also, since it would reduce storm water run-off from paved roads. A good start would be encouraging safe bike lanes, mixed use zoning, and affordable and convenient public transport.

But what do we do about the oceans? They are so big, and we’ve made such a huge mess of them. I feel depressed and hopeless when I see news about the dissolving coral reefs, the Pacific garbage dump, etc. Does anyone have ideas for things a small group of people could do to help heal the oceans?
