10) How are Coral Reefs threatened?
How are Coral Reefs threatened?
1st cause: Water pollution.
Reefs are harmed when human, animal waste or fertilizers are being dumped into the ocean. These pollutants increases the level of nitrogen around coral reefs which causes the algae to be overgrown. Floating trash which are thrown by humans are considered a pollutant too. Therefore, the water will be polluted and will be harmful to the reefs as it blocks off the sunlight.
2nd cause: Coastal Development
Coastal populations have risen. It has cause an increase of the pressures on coastal resources. This has led to many problems for coral reefs. In many areas, developers have constructed structures directly on top of coral reefs. Long ago, these reefs were destroyed by human pressures. Now, reefs growing near other coastal communities are experiencing the same coral degradation.
3rd cause: Careless Tourism
Tourist throw their sewage directly into the water which surrounds the coral reefs. Hence, it contributes to a coral reef degradation. Careless boating, diving, snorkeling and fishing may also damage the coral reefs. Whenever people grab, kick, walk on, or stir up sediment in the reefs, they contribute to coral reef destruction. Corals are also harmed or killed when people drop anchors on them.
4th cause: Carbon Dioxide
In the past few decades, the amount of carbon dioxide in the air has increased by one-third. This is harmful to corals because increased amounts of carbon dioxide are dissolving into the water, which appears to be dissolving the skeletons of corals. Therefore, corals in waters with large amounts of carbon dioxide form weaker skeletons, making them more vulnerable to damage from waves, careless tourists, and destructive fishers.
