Coral reefs provide many valuable services like supporting a high level of biodiversity and being an important source of food and income, especially for developing coastal communities. However, coral reefs are severely threatened by human activities such as overfishing, coastal development, pollution, and climate change with 10% already destroyed by 2000 and 32% in critical condition. Marine protected areas that restrict human access can help restore coral reef ecosystems by providing fish nurseries and replenishing surrounding areas.
