Coral reefs in the Caribbean decreased by nearly half in the last 50 years. Storms, algal growth and the impact of human activity are among the causes for the reduction
The conclusion is a group of researchers from several countries, who prepared the study ‘Coral Reefs of the Caribbean. 1970-2012 ‘.
The study warns that if action is not taken within twenty years there will remain not many reefs in the area.
The Caribbean reefs generate more than three billion dollars ( EUR 2.2 billion) in the fishing and tourism activities.
According to Jorge Cortés, researcher at the Centre for Research in Marine Sciences of the University of Costa Rica, quoted by EFE , catching fish that eat algae threatens the survival of corals.
The factor that join the ‘sediments, due to deforestation, changes to the coast for the construction and contamination’ reasons which ‘the corals die. “
Experts argue, therefore, measures for the protection of fish, such as the prohibition or limitation of certain types of fishing gear.
