Haha... I'm not quite that much of an activist. If I was there, I would have helped out for a while; but to be honest, while I don't think it's a fool's errand, or even a waste of time, I do think it's a remedy for a symptom, not the disease. The trash will be back soon, if not already. Hopefully the effort might have some small lasting effect as an example ... but in reality, for any meaningful change to happen, it will take time, time, and more time.
On another note: while I'm not a fan of trash, the bigger picture of the whole "let's make it better" mentality does give me pause. The trash issue is probably not the best example of what I mean, but it's an indicator of an overriding trend I frequently see. No, I don't like trash, (and I don't litter). Yes, cleaning up trash is a good thing. BUT the well meaning intentions have a flip side to them. Mostly it's the whole "OUR way is better" mentality, (which can boil down to WE are better). Of course the gringos would never say they mean it like this ... and probably don't on the surface, but it's the basis of the thoughts and actions. Many people I've talked to have purchased their slice of "paradise" but are bothered, irritated or even horrified by any of the thousands of things which are indicative of a "third world" nation... trash being just one of them. SO, they want to "fix" it ... in short, make it like "back home". As for me??? I chose the D.R. for ALL of it's qualities, and did so with eyes wide open. I like things a "little rough around the edges". I might be a bit of a hypocrite, since I DO like 24 hr electricity, I DO like working plumbing, I DO like my nicely appointed modern apartment in the well maintained gated complex ... but I'm not out to make the D.R. another Miami Beach either.
