Research demonstrates the adverse effects of pollution from sediment and chemicals on coral reefs, but limited studies address the role of recreational activities in exacerbating these effects. Coral reefs, with their diverse range of marine plants and animals, are critical to much more than just the beautiful underwater vistas for which Jamaica and the wider Caribbean are famous. KINGSTON, Jun 6 2012 (IPS) - Experts here fear that that the impact of climate change on Jamaica’s fragile ecosystems will worsen the ravages of human activity and destroy the country’s tourism industry. Over the last 50 years 80% of the corals have been lost due mainly coastal development and pollution. Habitat destruction is one of five global ecological pressures affecting the ocean, along with fishing pressure, climate change (including ocean acidification, water pollution and the introduction of alien species or genotypes. CARLOS GOENAGA. F rom tourism to marine recreation and sport fishing, coral reefs play an important role in the economies of countries all around the world. Staghorn coral is considered a threatened species of coral, and it's easy to guess that coral reef destruction will have a large impact on coral. Periodic disturbances increase the species diversity of shallow fore-reef areas and promote the establishment of coral communities on reef-flat and lagoonal zones. For Jamaica, these impacts and effects could be significant. Sedimentation (losing soil from upland areas) is an extremely important cause of coral reef destruction. Coral reefs provide coastal protection for communities, habitat for fish, and millions of dollars in recreation and tourism, among other benefits. In the Caribbean Sea and tropical Pacific ocean, direct contact between coral and common seaweeds causes When sediment and other pollutants enter the water, they smother coral reefs, speed the growth of damaging algae, and lower water quality. C oral reefs need clean, clear water to survive. It is instrumental in building partnerships and strategies for on-the-ground action to conserve coral reefs. When a coral reef supports fewer fish, plants, and animals, it also loses value as a tourist destination.

Coral Reef Threats. Harbor Branch Oceanographic Institution. These practices lead to habitat destruction and disintegration of the reef ecosystem. Cyclones generate various kinds of damage by mechanical destruction, change in sedimentation, increase in turbidity, lowering of salinity, and change in sea level. Hard corals form the backbone of the coral reef ecosystem, providing an intricate three-dimensional structure with hiding places and habitat for thousands of species of fish, invertebrates like clams, shrimp, sea stars, sponges, and anemones, sea turtles, and many other animals. We then examine two unusually detailed, long-term data sets from Heron Island, Aus- Coral reefs make up some of Earth's most diverse ecosystems. Learn how NOAA works to restore these valuable habitats. There are four or five serious things that can happen to it … for example, coral bleaching, sediment runoff, overfishing, physical destruction caused by boats or divers — if all that happens, then the reef is going to die. How Pollution Affects Coral Reefs . We present first a brief review of the impacts of physical disturbance (e.g., cyclones, hurricanes) on the community dynamics of coral reefs, with special attention to the effects of recurrent events. Gland, Switzerland, 8 June 2017 (IUCN) – Overfishing and the degradation of coral reefs across the Caribbean and Pacific islands are pushing many fish, including food sources like tunas and groupers, towards extinction, according to two regional Red List reports published today by the International Union for Conservation of Nature (IUCN). 1.

Strong waves caused by storms and hurricanes may smash into the reef, breaking up large corals and creating rubble fields. Areas with heavy bottom trawling have seen the coral coverage diminish by as much as 90 percent, leaving young fish without a habitat to mature in. The use of artificial fertilizers and pesticides on agricultural land also could be one of the cause of the damages of coral reefs in the oceans. Jamaica’s corals, reefs and its associated seagrass beds and mangrove forests are experiencing constant pressure from an array of sources namely coastal development, over-exploitation, pollution, habitat destruction, invasive species, Over 25 percent of the ocean species live in coral reefs though they cover less than 0.1 percent of the ocean. Charlie Veron, quoted by David Adam, How global warming sealed the fate of the world’s coral reefs , The Guardian, September 2, 2009 Damage was particularly severe in a unique mangrove/coral ecosystem in three bays within Virgin Islands Coral Reef National Monument, a National Park Service marine protected area. Cyclones generate various kinds of damage by mechanical destruction, change in sedimentation, increase in turbidity, lowering of salinity, and change in sea level. Coral Species. Since 1998 coral bleaching has become a common phenomenon around the world. For many, the clean beaches, vibrant coral reef systems, exotic marine life, and abundant seafood represent paradise. For example Jamaica’s catch composition has already shifted to being mostly of low value, “trash” fish, and particularly parrotfish – a species that has been shown to play an important role in coral reef health. Once coral reefs are damaged, they are less able to support the many creatures that inhabit them. Further bleaching and reef deterioration could reduce carbon burial and cause severe economic losses from destruction of reef fisheries, tourism, and shoreline protection from hurricanes and rising sea level. Coral reefs support jobs, tourism, and fisheries. The effects of mangrove deforestation on coral reefs are not well studied. the effects of changes in coral reefs on fisheries production in Jamaica,178 and the value of coral reef-related tourism in the Florida Keys.179 Other economic valuation studies have been broader-based attempts to quantify the diverse ecologi-cal services or “total economic value” of coral reefs. Coral harvesting for the aquarium trade, jewelry, and curios can lead to over-harvesting of specific species, destruction of reef habitat, and reduced biodiversity. The coral reefs are under threat due to environmental issues such as overfishing, pollution, hurricanes, and disease. Impacts from land-based sources of pollution—including coastal development, deforestation, agricultural runoff, and oil and chemical spills—can impede coral growth and reproduction, disrupt overall ecological function, and cause disease and mortality in sensitive species.

By one estimate, coral reefs provide economic goods and services worth about $375 billion each year. However, determining the main cause or causes of this decline has proven a much more contentious issue. storms, their effects on coral reef organisms and communities, and their short- and long-term consequences on reef functioning through succession and recovery processes. Tour boats can release human waste and gray-water discharge which can damage reefs, particularly in enclosed bays with limited water circulation. They occupy less than one percent of the ocean floor, yet are home to more than a quarter of all marine species: crustaceans, reptiles, seaweeds, bacteria, fungi, and over 4000 species of fish make their home in coral reefs. Overfishing and the destruction of habitats – including coral reefs – are causing the decline of many fish species, the report’s authors warn. (1981) monitored quadrats with photographs to show the effects of this storm on patterns of coral abundance and mortality . The trawls crush, scar, and destroy coral reefs, leaving little more than a trail of rubble in their wake. but rather by supporting coral reef and reef fish conservation. Readers of the human and reef-interaction coral reef literature will find considerable reason for skepticism about the future of coral reefs (Hoegh-Guldberg et al., 2007, Hughes et al., 2003, Jackson et al., 2001, Pandolfi et al., 2005).There are many problems and coral reef scientists have been busy documenting these problems in some detail. In 1996, extensive coral bleaching was noticed in a number of coral species at Johnston Atoll, a central Pacific coral reef. This is the path of a mass extinction event, when most life, especially tropical marine life, goes extinct. Interciencia JAN- FEB 1991, VOL.
