Coral reefs are being destroyed, mainly because of human activities.
Coral reefs are affected greatly by human activities. Humans have directly and indirectly been destroying coral reefs over the past few centuries. Humans have indirectly been contributing to the decline of coral reefs through overall environmental degradation and through human-caused global climate change. In the world, over 75% of coral reefs are threatened and more than 10% are damaged beyond repair (1). Directly, humans affect coral reefs physically, whether that be by driving boats directly over reefs or by fishing with nets that damage the coral. Coral reefs are sensitive habitats that must be protected now in order for them to survive.
What is the importance of coral reefs?
Coral reefs are some of the most biodiverse ecosystems on the planet. They support a vast number of fish and plant life by providing a food source and shelter. Coral reefs also act as natural protection to coastlines against ocean storms and floods. Coral reefs are environmental indicators of water quality as they can only tolerate narrow ranges of temperature, salinity, and water clarity. Without coral reefs, many species would have to adapt to new habitats or become extinct. Humans would not be able to make recreational use of coral reefs through diving, nor would humans be able fish as much or at all in regions where coral reefs had died. It is essential for the balance of marine ecosystems that coral reefs are not lost.
