Do you think it is possible to overuse our ocean resources? It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas.

but also the surrounding creatures that share these systems. The question that we want to answer is do we change our actions to protect the Great Barrier Reef?

The coral reef structure also buffers shorelines against waves‚ storms‚ and floods‚ helping to prevent loss of life‚ property damage‚ and erosion. Several million people live in U.S. coastal areas adjacent to or near coral reefs‚ and the well-being of their communities and economies is directly dependent on the health of nearby coral reefs. Reefs also protect the highly productive mangrove fisheries and wetlands along the coast‚ as well as ports and harbors and the economies they support. Globally

approximately 2050‚ there will be no fish in the sea. Overfishing is a serious issue that involves taking wildlife at increasingly higher rates than the species can replace.

Sharks and Australian Fisheries The Fishing industry is the 5th largest food producing industry in Australia. Annually it puts $2.2 billion dollars into our economy each year (afma.gov‚ 2013).
