Coral Reefs in Crisis

Rich in marine life and bursting with kaleidoscopic colour, coral reefs are one of the finest examples of nature’s bounty. They’ve often been described as the ‘rainforests of the sea’, and with good reason: coral reefs are the key components of some of the most complex and diverse ecosystems in nature. In fact, about 25 per cent of all marine creatures, including fish, molluscs and sponges, either depend on coral reefs for food or use them as spawning grounds.

Coral reefs are made up of colonies of tiny creatures called coral polyps. The polyps absorb calcium from the sea and use it to produce a limestone exoskeleton that expands as the creatures grow. Polyps feed on the larvae of shellfish, but they also need algae to thrive. Polyps enjoy a symbiotic relationship with algae – the algae live in the polyps’ tissues and provide them with nutrients; they also produce chemicals that help the polyps secrete their exoskeletons.

Ocean acidification is another reason why coral reefs are under threat. This occurs when excessive amounts of atmospheric carbon dioxide (one of the causes of global warming), are absorbed by the ocean. The result is that sea water becomes more acidic, thus compromising the polyps’ ability to secrete their exoskeletons. If global warming continues unabated, it’s likely that all corals could become extinct within the next 100 years.

Destructive fishing practices are one of the main reasons why the reefs of Southeast Asia are the most threatened in the world. Fishermen in countries such as Indonesia and the Philippines routinely use explosives or sticks of dynamite to kill fish, often causing irreparable damage to coral reefs in the process.

Another problematic form of land-based pollution is agricultural runoff. This is water that flows from farms through river systems and into the ocean, and it often contains high levels of nitrogen and phosphates. Increased nitrogen levels in sea water cause an overgrowth of algae; as a result, the corals are deprived of sunlight and eventually die. High levels of phosphates can also kill coral by impeding the growth of the coral polyps’ exoskeletons.

Many nations rely heavily on coral reefs for their livelihoods and food supply. The coral reef fisheries of Southeast Asia, for example, enjoy profits of about 2.4 billion dollars a year. In developing countries, roughly 25 per cent of potential fish harvests come from coral reefs. Fisheries worldwide employ about 38 million people, while another 162 million people are indirectly involved in the fishing industry. Should coral reefs continue to die out, the economic impact would be devastating, and many people would have to turn to alternative food sources to supplement their diets and their incomes.

And it’s not just the fishing and tourism industries that need coral reefs to thrive; coral reefs are also indispensable to the pharmaceutical industry. Research has shown that some of the organisms that live on coral reefs, such as sponges and seaweed, produce chemicals that have antibiotic and anti-inflammatory properties. These chemicals are the main ingredients of new medicines that are being formulated to treat a range of diseases and viruses. Thus, the degradation of coral reefs could have serious implications for the future of medicine. 

One way they are doing this is by applying low voltage electrical currents through seawater to
crystallize dissolved minerals onto steel structures. When this is done a white carbonate is
produced which is the same mineral that natural coral reefs consist of. These steel
structures are then colonized by corals at a very quick pace.

We can only hope that these and other efforts are enough to preserve our coral
reefs for generations to come.

A.  Though the situation seems dire, steps have been taken to try to protect and sustain our remaining
coral reefs. Some of the reefs in the Philippines, for example, have been declared ‘no-go’ areas to protect
them from overfishing. Also, some attempts have been made by conservationists to restore coral reefs.

B.  Coral mining is another issue that is of great concern to coral reef conservationists. Coral mining involves the
removal of large chunks of coral from reefs, usually for building purposes. The coral is then crushed and mixed
with other materials to make bricks or cement. In the Maldives, for example, building materials are quite scarce
and corals are the mainstay of the construction industry. The high demand for coral in the Maldives could
potentially wipe out many of the coral reefs in the country.

C. Aside from global warming and overfishing, one of the biggest contributing factors to the decline of coral reefs
is pollution. Because of rapid development in coastal areas, increased amounts of industrial waste, sewage,
oil and pesticides are now being disposed of in the ocean. These toxins are harmful to the reefs, and
pesticides in particular have been proven to interfere with coral reproduction and growth.

D. The decline of coral reefs will also impact the tourism industry. Half the gross national product of many
Caribbean countries is derived from tourists flocking to their beaches and reefs. The Maldives and the
Seychelles depend on coral reef tourism for a significant portion of their foreign income, and in Florida, USA,
reef tourism is a billion-dollar industry.

E. Coral reefs flourish in warm, tropical seas, but polyps are extremely sensitive to increases in water
temperature. Global warming has caused the surface water of the ocean to become warmer and the polyps
react to this rise in temperature by expelling the algae that they depend on for food. This process is called
‘blanching’: once the polyps have released the algae, they turn white and starve to death.

F. Of course, it’s not just land-based pollution that has impacted coral reefs. Marine debris (including plastic, glass
and discarded fishing nets that are simply tossed into the ocean), has also caused significant damage to coral
reefs. Floating debris, from plastic packets to bottles, can smother coral reef organisms or break down the
coral structure entirely.

G. It would be difficult to imagine a world without coral reefs, but, according to a recent global study, this alarming
prospect could easily become a reality. The study found that a third of all coral reefs are facing extinction,
primarily as a result of global warming, overfishing and pollution. The loss of coral reefs could have a
potentially devastating impact on tourism and the fishing industry, and on the economies of countries that rely
on coral reefs for their livelihoods. But what are coral reefs and how do they develop?

H. According to estimates, 19 per cent of the world’s coral reefs have already died, including 50 per cent of the
reefs in the Caribbean. This is in no small part due to the scourge of overfishing and the adoption of
destructive fishing practices, such as dynamite fishing. In parts of the Caribbean, overfishing has wiped out
virtually all the herbivorous fish that feed on the algae and seaweed that live on coral reefs. In the absence of
herbivorous fish, algae and seaweed grow at a rapid rate and eventually kill the coral.
