The Great Barrier Reef
The Ocean Floor is Not a Dance Floor
What is the Great Barrier Reef?
Human Effects on the Great Barrier Reef
Pollution has also made significant impacts on the Great Barrier Reef. Certain model estimates indicate that 22% of the world's coral reefs have been threatened by land-based pollution. This type of pollution includes fertilizers, herbicides, pesticides, human derived sewage, and large amounts of sedimentation from costal land development.
We Need This Reef
Healthy reefs also contribute to the economy through tourism. Diving tours, fishing trips, hotels, restaurants, and other businesses based near reef systems provide millions of jobs and billions of dollars all over the world. Not to say that this overexposure of the reefs isn't harmful, but it IS beneficial to humans and the economy that we do our best to protect the reefs and the animals living in them.
Lastly, coral reefs serve as a buffer between shorelines and incoming waves and therefore help to reduce erosion, property damage and loss of life.
