You say, what are you people doing, I say what are "YOU" doing? Talking and complaining is not the answer, doing is, sounds like you have an interest in helping, why not start by setting examples for others to follow, walking the walk is the best way, clean up your neighborhood, get people involved, stencil storn drains (NO GARBAGE)
I, more often then not, see way to many people leaving harmful litter behind that can kill or make sick, children, animals and also contaminate our waterways, so I'm doing something about it, I'm educating the people in my area and many other places, by cleaning beaches, lakes, rivers, streams, creeks, parks, storm drains, putting up and passing out posters, talking to City Hall, Local papers, TV, you can do the same, I wish you good luck, http://solution2pollution.blogspot.com/
Might give you some ideas, may the force be with you...KOTO One of the keepers of the ocean
