Modern corals are restricted to growing in warm, clear, well-lit, shallow water. Over the last two million years, coral reefs ha
ve undergone periods of great growth as well as mass extinctions. All BUT one catastrophic event has contributed to the changes in reefs over the years. That is
The answer is Climate change. It will take decades for the
coral reef to recover from the catastrophic climatic changes including El Nino
in 1997-98. Climate Change is the main and undeniable threats to the loss of
the corals. It has negative effects on coral populations in some ways. This
includes the Color Bleaching, Coral Disease, and Ocean Acidification.
