Coral bleaching in general.

The Great Barrier Reef is the biggest living thing on earth and is visible from space. It is located just off Queensland in northeastern Australia. The Great Barrier Reef is home to more that 1,500 fish species,  30 species of whales, dolphins and porpoise, 6 species of sea turtle and many more living creatures.

In the last 35 years, the temperature of the sea has risen by 1˚ celsius. Scientists are certain that this is due to global warming. Due to this rise in temperature, we are seeing coral bleaching on a huge scale.

Coral bleaching happens when temperatures rise and algae leave the surface of coral. Coral and algae depend on each other to survive as they are both food source to each other. When the algae leave, the coral starves, looses its colour. Coral doesn’t die when it has been bleached but is under more stress and subject to mortality. If the coral does die this can then have a dramatic effect on the food chain in the ocean.

If corals do serve after being bleached they will live but won’t be healthy.

Fact: It’s estimated that in the reefs upper third, half of its coral is dead.

The Great Barrier Reef is a place that I feel we should protect but I will probably try and promote change in the wider scheme of global warming, not just coral bleaching. Also, this isn’t the main global warming aspect that is affecting the UK. Also The Great Barrier Reef isn’t close to Plymouth so most people wouldn’t be too bothered. As Plymouth is England’s Ocean City I will probally look at ideas which make people aware that the sea levels are rising as this is what will affect us in the next few decades.
