I'm confused. Are you talking about:
A) Technical - A new garbage "disposal" system, somehow replacing the burning dump.
B) Cultural - Dealing with education, actual littering fines (or arrests), general street cleanup.
We all see the land and surrounding waters being used as f*cking garbage cans. In my opinion too much of the garbage doesn't make it as far as the dump to be "disposed" of, and that is the real problem.
Just like we aren't going to see a "big time marina" on Caye Caulker, we will also never see a proper garbage disposal facility. We don't need it. The dump is what it is.
