Why Coral is Important
They protect coastlines from the damaging effects of wave action and tropical storms. Provides habitats and shelter for many marine organisms.The fishing industry depends on coral reefs because many fish spawn there and juvenile fish spend time there before making their way to the open sea. The Great Barrier Reef generates more than 1.5 billion dollars every year for the Australian economy, because, people tour there.Corals assist in carbon and nitrogen fixing. Corals are the source of nitrogen and other essential nutrients for marine food chains

What Makes Coral Bleaching happen
Bleaching happens when corals are exposed to water temperatures that are warmer than usual. Warmer water puts stress on the coral. BLEACHING BEGINS WITH THE EVICTION OF ZOOPLANKTON. In 1998, a huge underwater heatwave killed 16% of the corals on reefs around the world. Atmospheric Administration announced the third global bleaching event in October 2015 and it has already become the longest event recorded impacting some reefs in consecutive years. As a result, the livelihoods of 500 million people and income worth over $30 billion are at stake.
