A problem of the destruction of coral reefs

Spawning aggregations are particularly vulnerable to overfishing. Biologically available nitrogen nitrate plus ammonia needs to be below 1.

This, combined with natural fluctuations of warmer ocean temperatures, has resulted in extensive coral bleaching around the globe, involving thousands of square miles of reefs. Matt Kieffer Bleaching leaves corals vulnerable to disease, stunts their growth, affects their reproduction, and can impact other species that depend on the coral communities.

Certain formulations of sunscreen are a serious danger to coral health. They live inside coral and share a symbiotic relationship with them. Tourist Economies Tourism has caused severe damage to the reefs. Tourism provides the basis for entire economies in many regions.

Its enzyme system dissolves the wax in stony corals, and allows the starfish to feed on the living animal. The process has been compared to osteoporosis in humans, and is leaving the fragile coral structures weak and even more vulnerable to anthropogenic fluxes.

Coral Reefs

But too much of a good thing can be bad for coral reefs. Dust transport to the Caribbean and Florida varies from year to year [19] with greater flux during positive phases of the North Atlantic Oscillation.

Environmental issues with coral reefs

The extent and severity of mass coral bleaching events have increased worldwide over the last decade. Increased CO2 Increases in the amounts of carbon dioxide found in water have had an adverse effect on coral. Defining and Understanding Coral and the Coral Reef 2.

Bleaching at the Great Barrier Reef When these algae leave the coral, the coral turns completely white. Malte Meinshausen, co-author of the study warned: Unsafe Fishing Practices result in the death of coral and other organisms that live in the reef.

In countries like the Philippines that regularly employ cyanide, more than thirty percent of the population lives below the poverty line.

This makes mass bleaching a uniquely challenging environmental management problem. By doing this, the plastic would not find its way into the ocean.

The pollution which has adversely affected the earth over the last century has had a dramatic effect on the health of the reefs.

How do coral reefs benefit the economy?

Today many reefs have 40 to 50 percent less coral than they did just 30 years ago. The polyps, which have tentacles to feed on plankton at night, play host to zooxanthellae, symbiotic algae that live within their tissues and give the coral its color.

Losing the coral reefs would have profound social and economic impacts on many countries, especially small island nations like Haiti, Fiji, Indonesia, and the Philippines that depend on coral reefs for their livelihoods. Scientists have long been pessimistic about the futurewith some reefs expected to vanish by When coral reefs come into contact with plastic waste, the incidence of disease rises fold.

Zooxanthellae provide oxygen and other nutrients to the coral polyps and the polyps give the algae the carbon dioxide they need to survive. It narcotizes the fish, which are then easily captured. Derelict abandoned fishing nets and other gear—often called "ghost nets" because they still catch fish and other marine life despite being abandoned—can entangle and kill reef organisms and break or damage reefs.

In addition to runoff, wind blows material into the ocean. Infographic Text Threats to coral reefs: Even though there are efforts to protect the coral reefs, the task has proven to be a difficult challenge due to many causes such as over fishing, water pollution, ocean acidification, coral bleaching, sedimentation, and coral mining.

Sometimes, people use a kind of fishing called blast fishing. The Negative Effects of this Destruction 4. All of these factors act in concert on coral reefs, and complex interactions between the threats leave coral reefs even more vulnerable.When the health of the coral is threatened, the existence of every other species is threatened, too.

The destruction of coral is leading to the endangerment and extinction of thousands of other species. 2. The Destruction of Coral Reefs. Coral reefs are being destroyed by anthropogenic fluxes in their environment.

Jun 25,  · Additionally, certain types of fishing gear can inflict serious physical damage to coral reefs, seagrass beds, and other important marine habitats. >The impacts from unsustainable fishing on coral reef areas can lead to the depletion of key reef species in many locations.

Watch video · Coral reefs are more than just exotic displays of color on the sea bed. The National Marine Fisheries Service, a division of the NOAA, placed their value for U.S.

fisheries at $ million. When sediment enters the ocean, it can smother coral reefs, depriving them of sunlight and nutrients.

Also, fish are unable to feed and coral polyps are unable to grow, leaving the area inhospitable to reef life.

Careless Tourism. Increased tourism is one of the major causes of the destruction of coral reefs. This law would also protect the coral in the coral reefs because it would keep people out of the coral reefs more, and it would allow the fish to reform the symbiosis of the coral and fish.

To rid the coral reefs of pollution, I would not allow the cities along the coral reefs to use plastic bags. Human impact on coral reefs is significant. Coral reefs are dying around the world. Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays.

Other dangers include disease, destructive fishing practices and warming oceans.
