Jessie, education is the key. Just as many divers used to molest the undersea wildlife for their own personal sensation, most have learned that this is bad practice. Due to have been educated, they don't do it anymore and strongly discourage others.
So when it comes to crocodile feeding, education will also be the key. The tourists need to be educated and law is right, the word needs to get out on a much broader basis than it is now. Perhaps notices in all of the hotel rooms along with all the other tourist paraphernalia, on the back of the room doors, on the notice boards in lobbies, a write up in the Belize Tourism Guide, handouts where tourists would normally go for info on tours, Seaduced/Tanisha/Dive Shops, etc. should help with the distribution of education in this regard, etc. etc.
It has also been my perception that Belize imposes fines for all manner of offences and often, those fined cannot pay and end up spending a little time in the clink. This doesn't seem to be the best way to handle things either. It is not my intention here to impose my cultural beliefs or ways onto Belizeans. I just would hope that those of you that live there and have some influence, would be willing to consider alternatives that are for the betterment of all.
