As someone living here, I've found the situation has actually improved...I find that there's less burning going on...thankfully children are being taught in school the dangers of burning all forms of garbage and especially plastics.
Just like the US (Woodsy Owl character - Give a hoot don't pollute) and Canadian campaigns we had growing up, the children are being educated and in turn they are educating the adults.
There have been several recycling projects in Negril...but they've not YET been sustainable. Change takes time...and the recycling WILL happen...we now have regular garbage pickup which Negril didn't have 10 years ago.
