L'pollution is killing the barrier Reef and over the next 10 years it will only lead to 5 per cent of its standard potential. The estimate comes from the Australian Institute of Marine Sciences (AIMS), based in Townsville.

Globally, the coral reefs have to face a myriad of threats, in particular thepollution of waters with the massive presence of gas and hydrocarbons, the rise in water temperature, the increase in the acidity of the oceans, thepollution caused by agricultural land, not to mention storms and cyclones that do not slow or prevent the growth of barrier Reef but they wipe out entire tracts of it. Usually, the barrier Reef manages to repair the damage caused by a cyclone within 10 years but cyclones are increasingly frequent and the impacts of climate change slow growth.


L'pollution atmospheric means that the seas absorb more carbon dioxide with an increasing acidification of the oceans. The pH tending towards acid damages the ability of corals to synthesize calcium carbonate. Furthermore, the increase in water temperatures is a source of stress and further slows down the growth of barrier Reef.

To say that the reef is at risk is an understatement barrier Reef is dying because ofpollution. The tourism industry is aggravating the situation. Numerous guided tours transform the growth sites of the barrier Reef in areas rich in exhaust gases from boats.

According to researchers Katie Cramer and Jeremy Jackson the main reason for the progressive disappearance ofcoral reefsit is due to phenomena such as deforestation and invasive fishing. Intensive fishing has halved the number of fish that feed on weeds, therefore the barrier Reef it must also fight with other living organisms for the survival of the species. The analysis by researchers Katie Cramer and Jeremy Jackson was conducted on the barrier Reef of the Caribbean andpollution of the area, the study was reported in this article.
