[Coral-List] Bleaching refuges

Funding should come from  environmental agencies in charge of
controlling land based pollution from rivers close to coral reefs.
Indeed it is quite difficult to be achieved  being it a very expensive
and complex intervention. I think it is worth  to try to demand
cleaning or improving pollution control of such polluted rivers by
local or national relevant stakeholders and governmental instances in
charge. Do you have any other idea about achieving it in some degree?
There are many examples of rivers where  luxuriant coral reefs thrived
very close to their mouth in the past.
