Coral Reef Degradation
Transcript of Coral Reef Degradation
What is coral reef degradation.
Coral Reef Degradation is caused by natural and man-made events. Some natural events are hurricanes, earthquakes, and volcanic eruptions.
Some Man-made event include Pollution, dumping trash and chemical pollution.
Water pollution comes in a variety of different sources, oil gas, and pesticide, They poison coral and marine life. They increase the level of nitrogen around coral reefs causing overgrowth of algae, which smothers reefs cutting off their sunlight.
The Global Coral Reef Alliance
Is a non-profit organization dedicated to growing, protecting and managing Coral Reefs. All of their scientists and support is through volunteer work. They primarily focus on coral reef restoration, marine diseases and other issues caused by global climate change, environmental stress and pollution.They employ a method which allows reefs to survive and recover from damage caused by excessive nutrients, climate change, and physical destruction.
U.S Coral Reef Task Force.
On June 11, 1998 President Clinton issued Executive Order 13089 on Coral Reef Protection "to preserve and protect the biodiversity, health, heritage, and social and economic value of U.S. coral reef ecosystems and the marine environment." The task force does coral reef mapping and monitoring, research, Conservation, Mitigation, and Restoration, and international cooperation.
Coral Reefs are underwater structures made up of Calcium Carbonate and secreted by corals. Which are polyps that cluster in groups. They occupy 1% of the ocean floor, and house 25% of all marine animals. Some common sea animals that live in the ocean are.
Trash also floats over the top of
coral reefs and cuts off their sunlight supply,a key ingredient of what polyps need to survive. Some trash also floats to the bottom and gets stuck on the coral reefs and damages them. And destroys homes of many sea animals and the coral reef.
What can we do to help?
1. Reduce pollution.
2. practice safe diving and snorkeling. And if you dive do not touch!
3. Don’t use chemically enhanced pesticides and fertilizers
4. Pick up waste.
5. Don’t anchor on the reef.
6. Support organizations that protect coral reefs. Your support is very important.
7. Respect local guidelines when visiting reefs. Ask at local environmentally friendly businesses how to be a reef-friendly tourist.
Organizations that help, maintain, and recover damaged coral reefs.
22% of the worlds coral reefs are threatened by land-based pollution. Including fertilizer, herbicides, pesticides, human derived sewage, and large amounts of sedimentation from coastal land development.
Coral Reef Bleaching
Coral Reef bleaching is the cause of runoff and storm generated precipitation. The known cause stressors of coral bleaching are local environmental degradation and reef overexploitation.
