[Coral-List] NOAA Press Release - 3rd ever Global Bleaching Event Underway

Sat Oct 10 12:41:10 EDT 2015

Dear Colleagues,

There is no need of rocket science, when everybody knows about the
exacerbating effect of nonpoint sources and punctual sources of
pollution towards the coral bleaching events. Other local stress is
caused by overfishing. It is our compromise as scientists to do
something to improve coral reefs conservation at all levels.
