Decline of US coral reefs - Big threat to marine ecosystems

US coral reefs have experienced serious decline in the lat couple of years, especially in the Atlantic, mainly due to the global warming, illegal fishing and marine debris. Coral reefs play very important role in marine ecosystems because many marine species use them as their habitats, and many fish species use coral reefs for breeding purposes. This decline is especially worrying in the Caribbean as according to experts the Caribbean has lost more than 50 percent of its corals. Waters are becoming more acidic because carbon dioxide that is released by fossil fuels combustion gets absorbed by the oceans. But climate change is not the only cause for coral reefs decline, there are also other factors like sewage, beach erosion, coastal development and especially overfishing.

Many marine species need coral reefs to live and grow

All these factors have one thing in common, they are all the result of the human action. Problem with the coral reefs is just one of many ecological problems caused by human action. The main reason for concern is the fact that we seem to be only acknowledging the problems but not doing nothing to solve them. As the result of this there is a lot of talk but very little action, and the ecological problems keep on piling up. How long will this last? Do we have to lose all our coral reefs to see the seriousnesses of our situation?
