Corals in danger – Coral bleaching is a serious problem

If you are a fanatic snorkeler ,you have heard for sure, or you have seen with your own eyes that the coral gardens are in danger. Coral reefs occupy less than 0.1% of the world’s ocean surface, but provide homes for around a quarter of all marine species.


It sounds really bad, but the reefs are simply dying around the world. If the reef is sick, starts bleaching.

Coral reefs face high dangers from air and marine pollution, diseases, overfishing and climate changing.

The list of factors which impacts reefs is long, the most importants are :

  • carbon dioxide sink
  • atmospheric changes, global warming
  • ultraviolet light,
  • ocean acidification
  • biological
  • algal blooms

Reefs are threatened well beyond coastal areas. The coral gardens are very sensitive ecosystems, and even one small change in the system could lead to the death of reef. In the last years, the reefs should face with dramatic changes, and they can not resist anymore.

This is a worrisome fact, that 19 % of the reefs are completely destroyed and a further 15% is likely to be lost over the next 10–20 years. Only 46 % of the world’ s reefs are in a good condition.

The reef destruction is the worst in the Philippines, where over 80 % of the corals are endangered and only 5 % is in good condition.

By the 2030s, 90% of reefs are expected to be at risk from both human activities and climate change.

By 2050, all coral reefs will be in danger.

We, underwater lovers should be aware of what can we and the next generations loose.

There are more and more people dealing with coral farming to restore the reefs.
