We definitely need to do more to save the Great Barrier Reef. The Great Barrier Reef is home to many different species and if we don't save the reef we will lose many different species of animals. Pollution and climate change is getting worse and worse each year and is causing more and more damage, not only to the Great Barrier Reef, but to the planet . The Great Barrier Reef is also a huge attraction for many people who come and visit Australia. This is why it is so important to keep the Great Barrier Reef alive and healthy.
Firstly, there are 1,500 species of fish, 411 types of hard coral, one-third of the world's soft corals, 134 species of sharks and rays, six of the world's seven species of threatened marine turtles, and more than 30…show more content… This dramatic increase is related to grazing and cropping expansion in the catchment, which has also affected the vegetation and wetlands. Pollution causes corals deteriorate, the water oxygen levels to decrease and increases nutrient levels. Yet the biggest threat to the Great Barrier Reef, is climate change. Climate change has a huge impact on the Great Barrier Reef because as the water temperature rises it affects our corals. This happens because coral is very sensitive to changes in temperature and if the water temperature stays high for too long then the zooxanthellae in the tissue of the coral will disappear, causing the corals to change colour to white. To add to that, as climate change becomes worse sea levels will rise, it is becoming more acidic and the sea currents are changing. These effects have many negative results for the reef and the animals living within them.
Lastly, the Great Barrier Reef is a huge attraction for people who visit Australia and people who live in Australia. In 2005 the Great Barrier Reef made more than five billion dollars, this is a great help to our economy. That means over five years the Great Barrier Reef would make around 25 billion dollars and that would go along way to help us. But if we keep pretending that nothing is happening it will be too late to reverse the effects. The Great Barrier Reef has had 2.19 million visitor days, do you really
