Great Barrier Reef

Well, isn't that a fun little question! If your nose bumped into the great barrier reef, you'd probably be wearing some snorkeling gear to explore its beauty. The reef is made up of tiny animals called coral polyps, and you'd find yourself in the lovely country of Australia. Just imagine the colorful fish and peaceful waters surrounding you - what a delightful experience that would be!

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.

= 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.

The Great Barrier Reef is located in Queensland, Australia, which follows the Australian Eastern Standard Time (AEST) zone. Additionally, during daylight saving time in Australia, the region follows Australian Eastern Daylight Time (AEDT).

Cyanide fishing has devastating effects on the ecosystem as it damages coral reefs, kills non-targeted marine life, and disrupts the balance of the marine environment. The use of cyanide can harm coral polyps, disrupt the food chain, and lead to long-term damage to the ecosystem's health and biodiversity.

The body of water that surrounds the Great Barrier Reef is the Coral Sea.

The explorer whose ship ran into the Great Barrier Reef was Captain James Cook aboard the HMS Endeavour in 1770. Cook's ship was severely damaged, and he had to spend several weeks repairing it before continuing his exploration of the area.

The straight-line distance is about 1,150.7 miles or 1,852 km. This is the true straight-line distance which accounts for the curvature of the earth and not merely a straight line drawn on a map.

There have been rare incidents of drowning at the Great Barrier Reef, typically involving snorkelers or divers who encounter difficulties while exploring the underwater environment. While the waters around the reef are generally safe, it is essential for visitors to be aware of their own limitations and practice proper water safety precautions.

The Great Barrier Reef is located off the coast of Queensland, Australia. Its latitude ranges from approximately 10 to 24 degrees south, and its longitude ranges from about 145 to 154 degrees east.

Cairns is approximately 40-60 kilometers away from the Great Barrier Reef, depending on which part of the reef you visit. On average, it takes about 1.5-2 hours by boat to reach popular reef sites from Cairns.

The food chain in the Great Barrier Reef begins with the producers like giant kelp and phytoplankton. The primary consumers are zooplankton and dugong. The secondary consumers are things like the anemonefish and the whale shark. Third level consumers are the manta ray and the blue-ringed octopus. The Apex predators in the Great Barrier Reef are tiger sharks and moray eels.

The Great Barrier Reef is important because it is the largest coral reef system in the world, providing habitat for numerous marine species. It also supports tourism, fishing, and protects coastlines from erosion. Additionally, the reef is crucial for scientific research and understanding the impacts of climate change on marine ecosystems.

Most island of the Great Barrier Reef are very little above seal level, thus would be swamped by a rapid rise in sea level brought about by glaciers melting. The same fate awaits the Maldives and many island groups, also countries like Bangladesh.

If I were in the Great Barrier Reef, I would be wearing a swimsuit, rash guard to protect against the sun, reef-safe sunscreen, and dive or snorkeling gear if I plan to explore underwater. It's important to be comfortable in the water while also protecting yourself from the sun and potential hazards.

The Great Barrier Reef is primarily composed of coral, which is formed by the accumulation of calcium carbonate skeletons from coral polyps. Additionally, there are some areas where sediments and sandstones can be found.

The Great Barrier Reef was formed by nature, with hundreds of years of living coral building upon the skeletons of other coral.

The corals that build reefs are not single animals. Coral is made up of colonies comprised of many individual animals called polyps, which join together. Coral polyps are a little like sea anemones, having tentacles that extend outwards, but they are not actually anemones.

Corals which create coral reefs have a symbiotic relationship with algae known as zooxanthellae. This algae, which lives within the tissues of the coral, causes a photosynthetic reaction which enables the polyps to make skeletons about three times faster in the light than in the dark. This means the corals deposit skeletons faster than the environment can remove it, and these skeletons build upon each other over time, creating a coral reef.

Coral is the skeletal bone of the living organism, it is made of limestone. So really, it is both bone and stone!

Once the ever-present sand ground down a person's teeth, infection and pain set in. Thus, dental disease became a common medical problem on ancient Egypt.

Some common barriers with videoconferencing include technical issues such as poor internet connection or software glitches, lack of familiarity or comfort with the technology leading to user error, and distractions at home or in the remote location that can disrupt the meeting. Additionally, language barriers, time zone differences, and cultural misunderstandings can also impact effective communication during videoconferences.

Perhaps the greatest risk is panic. When people panic, they tend to hold their breath and, when they ascend, the air in their lungs expands and can rupture a lung (or other similar medical conditions). It's easy to avoid though -- just breath normally. Staying down too long is also a problem. When you certify as a SCUBA diver, you'll be taught all about that. Another problem are big waves. The solution? Dont Dive When The Waves Are Big (like I had to say that! LOL ). Other dangers include hypothermia -- getting too cold, and exhaustion. The remedy for those is to get back on the beach or boat before they happen. I wouldn't worry about creatures eating me. You're more likely to get hit by lightning. If you NEED to worry about creatures, in California, far more people step on Sea Urchins than get attacked -- so watch where you step.

Diving is based on being calm and relaxed. If you can do that, the risks are very few.

but, the TRUE risk of SCUBA diving is that you will fall so in love with it that you will think of nothing else and feel empty inside until the next time you DO get to go SCUBA diving again
