How is the Great Barrier Reef going to be helped in the future?

Answer 1

It most likely won't be helped, but it will be destroyed by a special type of starfish if we can't kill them first. Do a Google� Images� search for "Thorn Of Crowns Starfish, Great Barrier Reef" Or do a normal Google� search, if you don't get any images. Try separating them. The Starfish is only able to be killed by a snail, one that has a harpoon filled with poison at the tip. This doesn't really answer your question, but it tells you how to find the answers. Good luck, my friend. In many countries they are sinking old ships so plankton will grow on it and try to bring back the natural order of the oceans. Depending on what the trouble is you are worried about. As for the star fish problem we can't really fix that too easily. We would have to start hunting starfish, which for some reason environmentalists don't like.

If your concern is that the reef will die as the water level rises then you shouldn't fear. Coral grow where they can survive. Meaning they won't be growing downwards into the colder water. They naturally grow upwards towards the heat of the sunlight. This means as the ocean levels rise the reef will grow upwards too. Thus our beloved reef that has wrecked many a ship is saved, by itself.

Ultimo NSW 2007 More than ten of the world's major cities have pledged their support for Earth Hour 2008, the WWF led-climate change initiative that has gained worldwide momentum. Earth Hour will take place at 8pm on Saturday March 29 next year with more cities expected to sign up in coming weeks. Sydney, host of the inaugural Earth Hour campaign held on March 31 this year, will be joined in 2008 by Melbourne, Brisbane, Chicago (USA), Copenhagen (Denmark), Toronto (Canada), Manila (Philippines) and Tel Aviv (Israel) and other cities in turning off lights for one hour in a global demonstration of the world's readiness to tackle climate change head on.

= Great Barrier Reef = The Great Barrier Reef includes over 2,900 reefs, around 940 islands and cays, and stretches 2,300 kms along the Queensland coastline. The Great Barrier Reef Marine Park is 345,000 km2, that's larger than the entire area of the UK and Ireland combined! Bullray swimming in the Great Barrier Reef

© WWF-Canon/Jürgen FREUND The reef is immensely diverse with 1,500 species of fish, 359 types of hard coral, one third of the world's soft corals, 175 bird species, six of the world's seven species of threatened marine turtle and more than 30 species of marine mammals including vulnerable dugongs. Add to that stunning marine life are 5,000 to 8,000 molluscs and thousands of different sponges, worms, crustaceans, 800 species of echinoderms (starfish, sea urchins) and 215 bird species, of which 29 are seabirds. The Great Barrier Reef is listed under all four natural World Heritage criteria for its outstanding universal value. Protecting the reef has benefits beyond conservation - it is also an investment that helps provide security for coastal communities and provides significant benefits to the Australian economy. Reef industries, which are reliant on a healthy environment in which to operate, contributed approximately $5.8 billion to the Australian economy in 2004 and employed about 63,000 people. Historically, the Reef has been regarded as a well-protected, pristine wonderland - a place of delicate corals, abundant fish life and a haven for other marine life. As scientists came to understand more about the reef's complexities, a different picture emerged - overfishing, land-based pollution and coral bleaching exacerbated by increased sea temperatures due to global warming are all impacting upon its natural wealth. Immediate action was required to protect the reef because only 4.6% of the reef was fully protected. As a result of public campaigning and pressure from WWF, the Australian Government committed to a plan to protect 33% of the reef. The Great Barrier Reef Marine Park (GBRMP) zoning plan was implemented in 2004. Its most significant feature is a network of marine sanctuaries that stretch from the Park's northernmost to southern boundaries. This is the world's largest network of marine sanctuaries and covers over a third of the Marine Park - protecting over 11 million hectares. Scientists have identified 70 different distinct biological regions in the GBRMP, representing the entire range of its plants and animals. A minimum percentage of each biological region is protected from fishing in order to maintain the health and resilience of the ecosystem and to protect the full range of biodiversity in the marine park. Crown-of-thorns starfish - one of the threats to the Great Barrier Reef

© WWF-Canon/Jürgen FREUND The amount of sediment flowing from the land into the marine park from its catchment area has quadrupled over the past 150 years due largely to grazing and cropping expansion in the catchment and loss of native vegetation and wetlands. The reef has experienced two mass coral bleaching events - in 1998 and 2002. Bleaching was more severe in 2002, with aerial surveys finding that almost 60% of reefs were bleached to some degree. Not only is the reef subject to high levels of fishing pressure, other fishing practices such as seafloor trawling for prawns are still permitted in over half of the marine park, resulting in untargeted fish capture (by-catch) and destruction of the seafloor. Maintaining a well funded, enforced and monitored network of marine sanctuaries throughout the GBRMP is essential to protect representative areas, as well as areas that are of special or unique biological value. Healthy levels of fishing effort in the marine park are needed to safeguard the Reef's biodiversity. The joint Australian and Queensland governments' Reef Water Quality Protection Plan confirms that effective action must be taken now to reduce land-based sources of sediment, nutrient and pesticide pollution further damaging in-shore reefs. The future impacts of global warming must be included in government plans regarding the Reef at a local level, and action must be taken at a national level to reduce CO2 emissions.
