- Destructive fishing practices: These include cyanide fishing, blast or dynamite fishing, bottom trawling, and muro-ami (banging on the reef with sticks). Bottom-trawling is one of the greatest threats to cold-water coral reefs.
- Overfishing: This affects the ecological balance of coral reef communities, warping the food chain and causing effects far beyond the directly overfished population.
- Careless tourism: Careless boating, diving, snorkeling, and fishing happens around the world, with people touching reefs, stirring up sediment, collecting coral, and dropping anchors on reefs. Some tourist resorts and infrastructure have been built directly on top of reefs, and some resorts empty their sewage or other wastes directly into water surrounding coral reefs.
- Pollution: Urban and industrial waste, sewage, agrochemicals, and oil pollution are poisoning reefs. These toxins are dumped directly into the ocean or carried by river systems from sources upstream. Some pollutants, such as sewage and runoff from farming, increase the level of nitrogen in seawater, causing an overgrowth of algae, which 'smothers' reefs by cutting off their sunlight.
- Sedimentation: Erosion caused by construction (both along coasts and inland), mining, logging, and farming is leading to increased sediment in rivers. This ends up in the ocean, where it can 'smother' corals by depriving them of the light needed to survive. The destruction of mangrove forests, which normally trap large amounts of sediment, is exacerbating the problem.
- Coral mining: Live coral is removed from reefs for use as bricks, road-fill, or cement for new buildings. Corals are also sold as souvenirs to tourists and to exporters who don't know or don't care about the longer term damage done, and harvested for the live rock trade.
- Climate change: Corals cannot survive if the water temperature is too high. Global warming has already led to increased levels of coral bleaching, and this is predicted to increase in frequency and severity in the coming decades. Such bleaching events may be the final nail in the coffin for already stressed coral reefs and reef ecosystems.

Causes and effects of destruction of coral reef?
Cyanide fishing, Dynamite fishing and "Muro-ami" can also cause Coral Reefs Destruction due to chemicals that are involved in these types of fishing.

What are the harmful practice of man that can cause destruction of coral reef?
Coastal congestion,coastal pollution,and coastal migration contribute to the destruction of coral reefs.Coastal construction also disturbs the coral reef ecosystem.
How can farming lead to the destruction of coral reef?
Runoff from farms near coral reefs can cause two basic problems; sedimentation and nutrification. Sedimentation means that silt and dirt particles get washed into the ocean, blocking out light, and landing on and smothering reef animals. Nutrification causes large algal blooms that can easily overgrow and crowd out coral reef animals.
What are the measures implemented to reduce the impact of coral reef destruction in any Caribbean territory?
You can write a letter to the garbage people and tell them what danger this impact has on the coral reef. ( I am worried 2)
What is often responsible for coral reef destruction?
Water pollution is one of the major things that destroys coral reef. When I went snorkeling in the Bahamas, we weren't allowed to wear any kind of sunblock, suntan lotion, etc. into the water, because even that can destroy coral reef.
How did rainbow parrot fish got endangered?
Because of the mangrove destruction that is connected to the coral reef
Is the great coral reef the same as the Great Barrier Reef?
No. A coral reef is just a reef made out of coral. There are many other kinds of reefs. A coral reef is just one kind. The Great Barrier Reef is a specific coral reef. There are many other coral reefs in the world.
What type of site is the Great Barrier Reef?
The Great Barrier Reef is a coral reef.
Where do needlefish live?
in the coral reef in the coral reef
Does it rain in the coral reef?
It does not rain in a coral reef because the wind near the coral reef is dry and has no moisture
What problems are there in the coral reef?
Hurricanes, Cyclones, Typhoons, Earthquakes, or Plagues are some of the natural causes of dying Coral Reefs
