Question

How are coral reefs decreasing in ocean? What is its impact in ecosysyem of that region

Answer 1

Answer:

Coral reefs are dying around the world. Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. ... Climate change, such as warming temperatures, causes coral bleaching, which if severe kills the coral.

Climate change will also bring sea level rise that may result in drowned coral reefs, and more intense storms that produce excessive nutrient or sediment runoff. The overfishing of herbivorous fish and excess nutrients decrease coral's resilience in the face of increased CO2.
