Importance to ocean life
In the polluted or murky water coral reefs cannot exist, they act as the filtration system of
ocean and consume the particles present in the ocean. It leads to enhanced clarity and quality of
the sea’s waters. Coral reefs also control the amount of carbon di oxide in the ocean, and make
the marine life livable for ocean creatures. There are number of species are living in coral reefs
coral reef are actually are home to nearly 20 percent of marine life (Graham & Nash, 2013).
Benefits to human and environment
1. Coral reefs are the great source of food for human. Fisheries both big and small rely on
the coral directly and indirectly as the mean source of livelihood. There are more than
4000 type of fish species found nearby coral reefs. A large population of human resides in
the developing nations and island nation and therefore they directly depend on the ocean
food, as ocean animal are the great source of protein and other nutrients. It has been
identified that coral reefs can provide 5 to fifteen tins of fish, crustaceans, mollusks and
other invertebrates /km2.
2. Coral reefs also provide some species that comprise pharmaceutical compounds use drugs
to treat dangerous diseases (Graham, Jennings, MacNeil, Mouillot & Wilson, 2015).
Benefits to the environment
1. By their huge establishment between the initial few tens of meters deep the surface, the
coral reefs are recognized as highly effective for absorbing elements coming from the
ocean. They decrease the damage in circumstance of storms, typhoons, and in certain
way, the tsunami’s energy. The powerful currents of ocean could easily corrode famous
