The Great Barrier Reef By Scott Batten


The Great Barrier Reef, off the coast of Queensland in northeastern Australia is the largest living thing on earth, and is even visible from outer space. The Great Barrier Reef is a famous tourist destination through out the Reef People are allowed to swim sail and dive. Humans have had a big affect on the reefs because of pollution,mining and global warming this also a problem because it is killing the Reef and causing a lot of different health problems for it. weather events such as cyclones and tornadoes are damaging the Reef, some of the fish are also digging holes into coral which can damage it.


The Great Barrier Reef is a 2,300 km long ecosystem and is made up of 600 different types of coral. It is 344,400 km2

The Great Barrier Reef is home to over 2,900 different types of coral in fact it is said that it holds one third of the worlds soft coral. And 411 different types of hard coral.

The Great Barrier Reef is also home to 1,500 different types of fish, it is home to 134 different breeds of sharks and stingrays, and Six of the worlds 7 species of endangered turtles

The Great Barrier Reef has been challenged over time because of the rising temperatures due to global warming,Weather events and Tourism have been a big factor in the reefs wellbeing to due to the management of waste which causes pollution.

There are 14 main types of coastal ecosystems that are in the Great Barrier Reef (-coral reef-lagoon floor-islands-open water-sea grasses-coastline-estuaries-fresh water wetlands-forested flood land-health and scrubland-grass and sedge land-woodlands-forests and rainforests) these are linked between water and land.


The Great Barrier Reef has been affected by tourism mainly in a bad way because of people dumping a lot of waste into it mainly rubbish which damages the ecosystem. Fragile coral is being broken from Reef walking, and boats driving along the Reef are polluting the waters. Suntan lotion and people's sweat are also damaging the Reef. Tourism has affected a lot of sea life scaring away fish and swimming where they normally live which scares them off, seabirds and turtles are eating rubbish which is damaging the population.

SustainbilTY aNd scale

An example of a problem damaging the Reef is tourism and dumping of trash and pollution.

To keep the Reef healthy Australia has banned the disposal of port related capital dredge material in the world heritage site. So far it's made a good huge impact.

Australia is also putting funding into monitoring and the protection of the Reef for a long term sustainability plan.


Climate change has had a huge affect on the Great Barrier Reefs health. The Reef is highly vulnerable to rising sea temperatures. Hard corals are susceptible to coral bleaching from higher than normal sea temperatures. Coral bleaching is suspected to happen more often In the future with greater severity. Making it hard for corals to recover after the event.

As a result the abundance of living corals on reefs might decline. Coral community's are increasingly going to be dominated by the types which can tolerate the changes much better.
