The Great Barrier Reef is the largest coral reef system in the world, stretching for over 1400 miles along the coast of northeastern Australia. It is a UNESCO World Heritage Site and is home to a diverse range of marine life.
However, the Great Barrier Reef is under threat from a number of factors, including rising sea temperatures, coral bleaching, ocean acidification, and pollution.
Rising sea temperatures are causing the corals to bleach and die. Coral bleaching occurs when the water temperature is too high for the corals to survive. This can be caused by a number of factors, including El Niño events and global warming.
Ocean acidification is also a threat to the Great Barrier Reef. Ocean acidification occurs when the ocean absorbs carbon dioxide from the atmosphere, which makes the water more acidic. This can damage the coral reefs and make them more susceptible to bleaching.
Pollution is another threat to the Great Barrier Reef. Pollution from land-based sources, such as fertilisers and pesticides, can enter the ocean and damage the coral reefs. Pollution can also kill the fish and other marine life that live in the reef.
The Great Barrier Reef is a valuable natural asset and is under threat from a number of factors. It is important to take steps to protect the reef and ensure that future generations can enjoy it.
