Threats to Coral Reefs: Human Impacts
– Pollution’s effect on reefs
– Toxins and waste damage coral health
– Overfishing harms reef ecosystems
– Excessive fishing depletes fish populations
– Destructive fishing practices
– Practices like blast fishing destroy coral structures
– Climate change induces bleaching
– Warmer temperatures lead to loss of algae symbionts
|
This slide aims to educate students on the various threats that coral reefs face due to human activities. Pollution includes the introduction of harmful substances like plastic waste and toxic runoff into the ocean, which can smother corals and reduce water quality. Overfishing can upset the delicate balance of the reef ecosystem, leading to a decline in certain fish species and affecting the overall health of the reef. Destructive fishing practices, such as using cyanide or dynamite, can physically damage the coral structure. Lastly, climate change is causing increased sea temperatures, which leads to coral bleaching a phenomenon where corals expel the algae living in their tissues, causing them to turn white and become more susceptible to disease and death. Encourage students to think critically about these issues and consider ways to mitigate these threats as part of conservation efforts.
Conservation Efforts for Coral Reefs
– Marine Protected Areas (MPAs)
– MPAs are regions where human activity is restricted to protect marine ecosystems.
– Sustainable Fishing Practices
– Practices like size limits and gear restrictions to reduce overfishing.
– Coral Farming Initiatives
– Growing corals in nurseries then transplanting them to damaged reefs.
– Restoration Projects
– Projects aimed at repairing damaged reefs, often involving local communities.
|
This slide focuses on the various conservation strategies being implemented to protect and restore coral reef biodiversity. MPAs are designated zones where activities like fishing and tourism are managed to prevent ecosystem damage. Sustainable fishing practices are crucial to prevent overfishing and maintain fish populations. Coral farming involves cultivating corals in controlled environments, which are later used to replenish and stabilize damaged reefs. Restoration projects may include a variety of activities, from physically repairing reef structures to reintroducing native species. Encourage students to discuss the importance of each method and how they can contribute to conservation efforts.
Threats to Coral Reefs: A Case Study
– Examine a threatened coral reef
