using electricity to save reefs

We don't have people using dynamite or cyanide to fish on Roatan (thank goodness), but we did have a coral bleaching episode a few years ago caused by water that remained too warm for too long. Roatan's reef have naturally recovered since then. This is an interesting approach being used in Bali to assist the coral's recovery. Of course, if the electricity comes from polluting fossil fuel generators, one has to wonder if the net effect would be positive.
