No future for the Great Barrier Reef unless there is change in human behavior towards the environment
From outer space, the Great Barrier Reef is the largest living organism made structure that can be seen. The reef spreads over 2,300 kilometers and is located off the seashore of Queensland, Australia. Unfortunately this great mega structure finds itself facing possible extinction as it is currently going through a major bleaching catastrophe due to climate change.
The problem at hand
According to Richard Vevers a chief executive of an agency raising awareness of environmental problems, the Great Barrier Reef is fast becoming a pile of dead corals covered in algae coupled with decomposing flesh from dying animals or marine life that once inhabited the reef. According to the researcher, a coral is said to bleach when its polyps spit out algae which normally thrives inside the polyps due to external environmental stress. The release of algae by the polyps causes them to become transparent allowing you to see their skeletal structure. Once this happens the coral dies as its nutrition is 90% dependent on the algae. In time the dead corals become substituted by seaweed. What really causes this science phenomenon? The researcher goes on to state the following problems that are contributing to the deterioration of the Great Barrier Reef.
Vevers states in a news article that an increase in water temperature is the major trigger of the release of algae by the coral polyps. One of the major causes of water temperature increase in the seas and oceans is water pollution. The list of human activities that causes water pollution is endless. Ranging from the uncontrolled use of inorganic fertilizers in agriculture, the dumping of nuclear waste in the seas, discharge of industrial sewage into river channels which in turn lead to seas and oceans has resulted in a general change in the natural equilibrium of the aquatic environment thus leading to an increase in water temperature which affects the corals of in the seas.
The use of carbon fossil fuels has made a major contribution to general global warming. The carbon gases that are emitted from the use of oil based fuels produces chemical which have resulted in the depletion of the ozone layer. The ozone layer is responsible for reducing the effects of radiation from the sun. However due to continued emission of atmospheric pollutants there is now a section where there is a hole in the ozone layer. This has led to increased amounts of solar radiation reaching the earth’s surface which in turn increases the temperature of the earth’s surface as well as its water bodies.
What needs to be done?
The world’s governments, including the Australian government need to come together and reach an agreement (putting aside politics) to cut down on their carbon emissions. Of late all governments are in agreement on paper but in practice none of them is actually abiding to their promises. Hence there is need for serious campaigns from environmental activists such as Vevers, to show people real life images on world news platforms so they can see for themselves what is really happening to the environment out there.
