Environmentalists are sounding the alarm – the Earth may be losing the most beautiful underwater wonders within the next 20-40 years. So, for example, Australian coral reefs could die before 2030.

Research of the World Resources Institute says that by 2030 90 per cent of Australian reefs will be affected by warming seas and oxidation, which can lead to death. If this sad prediction come true, then Australia will lose not only the divers who come here from around the world to admire the beautiful coral and many species of marine life that depends on the corals.

In other regions situation is not better. In its report Institute pointed out that not only Australian, but the Indonesian reefs are under a threat of destruction. The Earth could lose in 2050 all the coral reefs in the world's seas and oceans. This will cause significant economic damage to the 27 countries in the Caribbean, Pacific and Indian Oceans. Most at risk now of losing the underwater treasures, except for Australia – to Indonesia, the Philippines, Tanzania and Haiti. The main reason for the sad prognosis – environmental pollution, climate change and overfishing.
