The Great Barrier Reef is a very popular tourist destination with over two million visitors each year. The Reef is the largest in the world composed of about 2,900 individual reefs. The Great Barrier Reef is larger than the United Kingdom, Holland and Switzerland combined. There are many species that of animals and fish that live in the reef. These include 30 species of whale, dolphin, and porpoise, 6 species of turtles that come to the Great Barrier Reef to breed. Also 215 types of birds, 17 species of sea snakes, 1,500 fish, and 330 types of ascidians
Coral Bleaching (Problem and Solution)
The Climate in Australia is changing causing the water to heat up. This won't just affect the coral in the Great Barrier Reef, it will affect the population and habitat of marine animals. Climate change is also predicted to cause the acidification of oceans, having vast consequences on the Reef. Many parts of the Reef are showing the effects of climate change, such as coral bleaching, which is become increasingly more frequent and severe, and decreased density of coral structures. Also, disease in coral and crown of thorns starfish and cyanobacteria seem to be occurring more with greater impact. This is a problem. Even though there are so many problems with the Great Barrier Reef, there are still many solutions. If we want to keep the Reef alive, we need to reduce the amount of carbon dioxide in the air to about 400 ppm. Pollution is aso a big threat. Pollution helps some plankton grow, which is perfect for young crown of thorns starfish. The crown of thorns starfish also feed on coral polyps which means they are feeding on the Great Barrier Reef. If we stop pollution, we can help the Reef thrive.
