What are 5 threats to the coral reefs?

Threats to Coral Reefs

  • Physical damage or destruction from coastal development, dredging, quarrying, destructive fishing practices and gear, boat anchors and groundings, and recreational misuse (touching or removing corals).
  • Pollution that originates on land but finds its way into coastal waters.

What are six threats to a coral reef?

Reefs at Risk Revisited (RRR), cited six primary stressors leading to the majority of decline in coral reefs: overfishing and destructive fishing, watershed-based pollution, marine-based pollution and damage, coastal development, thermal stress, and ocean acidification [3].

What are the threats to coral throughout the world?

Pollution, overfishing, destructive fishing practices using dynamite or cyanide, collecting live corals for the aquarium market, mining coral for building materials, and a warming climate are some of the many ways that people damage reefs all around the world every day.

What are the major natural threats to coral reefs?

Coral reefs are sometimes disturbed by natural forces, such as extreme rain events that dilute seawater, waves associated with hurricane-force winds, volcanism, earthquakes, and thermal stress from unusually warm water (such as El Niño events).

What are two major threats to coral reefs?

Coral Bleaching. The coral bleaching is happened because the algae that supplies food for the coral is gone.

  • Sedimentation. The coral reef can’t live in the dirty place.
  • Ocean Acidification.
  • Rising Sea Level.
  • Pollution.
  • Radiation.
  • Development.
  • Mining.
  • Overfishing.
  • Storm.
  • What are some threats of the coral reef?

    large and strong storms like cyclones and hurricanes are a very common threat to shallow coral reefs.

  • Climate Change. One of the biggest threats to coral reefs is climate change.
  • Predators.
  • Over-fishing.
  • Dangerous Fishing methods.
  • Water pollution.
  • Sedimentation.
  • Ocean Acidification.
  • Tourism.
  • Diseases.
  • What are the problems that coral reefs are facing?

    Climate Change. Corals live in a symbiotic relationship with algae and both benefit from each other.

  • Irresponsible Tourism. Tourism thrives around coral reefs as tourists love to explore the colorful ecosystem of the reef.
  • Irresponsible Fishing Practices.
  • Coral Mining.
  • Pollution.
  • Increased Sedimentation.
  • Why are coral reefs in danger?

    Humans are the biggest threat to the integrity of a coral reef. Because of pollution, boat traffic, and aggressive fishing, reefs are now considered in danger and are protected under the Great Barrier Reef Marine Park Authority, an Australia-based institution.
