Environmental Impact on The Great Barrier Reef
The environment poses a huge threat on the reefs. Lots of people think that the most significant threat to the reef is climate changes, or the El Nino effect which is rooted in the tropical Pacific Ocean, and occurs every 3 to 7 years. Another big issue is coral bleaching. Many of the corals at the upper edge of Australia are getting bleached. If the water doesn’t cool within a month, the coral will die of starvation. Another environmental issue in the reefs is Crown of Thorns Starfish. These Starfish are a coral reef predator that preys on coral reef polyps.
