On-going climate change will have and has already caused many consequences for the Great Barrier Reef. This change will and has directly impacted many species of fish, invertebrate, mammals and birds along with many aquatic and terrestrial plants. There are also substantial impacts on the functioning of the reef. The biggest concern about climate change and the Great Barrier Reef is the rise in sea temperature which will affect the movement of water around the reef and the nutrient cycle on the reef which also means the chemical structure which will be altered because of the increased amount of CO2 dissolved into the water. With…

Coral reefs and how chemical substances can affect these living organisms is what the research is conducted on. We tend to have a genuine love for coral reefs whenever we view someone’s scuba diving photos. Seeing fishes swim around coral reefs is what many assume is the purpose of the reefs, but many do not know their real purpose. However, it comes down to learning the importance of coral reefs and how to protect these species that are very much a part of our ocean. This investigation is important because just like everything in our sea there is, importance in these reefs in our ocean. Not to mention, if we do not learn and protect these species there will be severe consequences for the world that we live in.…

“Some coral species lose their skeletons altogether” (Fine & Tchernov, pg 9, par 4), “and skeletal growth of recent recruits can be disrupted” (Cohen, pg 9, par 4). So the disruption of the skeletal growth can then make the reefs weaker and more vulnerable to damage and destruction. The acidity of the ocean doesn't just effect the skeletal growth of the coral reefs either. “This is damaging many ocean species that use calcium carbonate to form their skeletons and shells. Studies have shown that calcium carbonate formation is disrupted if water becomes too acidic”(Fujita, pg 2, par 8). So not only coral reefs being effected in skeletal growth, but all organisms that have an outer shell or exoskeleton have trouble developing a strong shell as the acid restricts the calcium production. Another effect that climate change brings about is rising sea levels. “The most obvious consequence of sea level rise will be an upward shift in species distributions. Most species are expected to be able to keep pace with predicted rates of sea level rise, with the exception of some slow-growing, longlived species such as many corals” (Knowlton, pg 10, par 1).” However, dramatic ecological changes could result from decreased habitat availability within a…

A lot of humans and businesses depend on the Coral Reef as a food supply, protection and for jobs, especially on the islands of Hawaii were most of time people spend their time in or under the water. Hawaii is known as Paradise Island because of its healthy and beautiful Coral Reef and understanding how to keep it healthy is extremely important to me because Coral Reefs are lowly depleting and I want to know why and what there is I can help do to save them, cause they are a great defense, buffering the waves, storms and potential floods which in turn help property damage and erosion. Coral Reefs help support commercials and businesses that support tourism and popular fishing and surfing that takes place around the islands coast. The 21st century has relied on the Coral Reef heavily calling it the “Medicine Cabinet” with the Coral Reef plants and some of the animals that live in it new sources of medicine to help treat major diseases like Cancer, heart disease, arthritis and viruses. The protection of the coral reef means a lot to me and although I haven’t been on the island long I am putting myself in those who have and look back on tragic events that have damaged the coral reef like the February 5th 2009 USS Port Royal ship grounding that destroyed millions of dollars of coral reef and not only did the ship do that but they also dumped their waste that was stored on the ship in the nearby waters which also polluted the water and killed hundreds of fish and possibly the remaining coral reef in that area, now for someone to destroy that much of the history gets me…

Climatic conditions generally determine the distribution of coral reefs as they can exist in both temperate and tropical waters. Through global warming the coral reefs in the Persian Gulf have now adapted through winter temperatures below 18 ° Celsius where they were unable to grow previously therefore the warming conditions of the planet are in fact allowing coral reefs to grow in areas they previously couldn’t but as…

Global warming puts coral reefs in danger as warmer water increases the possibility of coral diseases and Global warming raises sea levels, and that could threaten cities in a number of states. Sea levels have risen about seven inches in the last 100 years, which is more than in the previous 2,000 years combined, according to Do Something, a nonprofit aimed at empowering young people. And they could rise another 19 inches by 2050. That means cities like New Orleans and Miami could start to look like Venice. Rising water levels can also put fragile coral reefs in danger. Coral relies on sunlight, which could become scarce as water levels rise. the rising sea levels makes it more difficult for coral to receive adequate sunlight.…

The coral reef is a home to more than 3,000 species of fish, 700 species of hard coral and around 100 other species. Scientists say that there could be 1-8 million undercovered species. If not protected all these species have nowhere to go and the undiscovered species will likely not be discovered. We cannot let these species die a whole ecosystem will be lost. Ocean Conservancy was created in 1972, they offer 2,300,000 jobs to people. Over the 25 years the organization was around they were able to clean up 144,606,491 pounds of trash. They strive to keep the ocean healthy and capable of having wildlife live in it. They also want to keep coastal areas healthy as well. Ocean Conservancy is a nonprofit organization that…

Coral reefs are home to many fishes and plants. Because of global warming, 16% of the world’s coral reefs were wiped out in one year alone (“Global Warming and Coral Reefs”). Ocean temperatures have also risen by 1.3 ° Fahrenheit since the last 19th century (Coral bleaching and ocean acidification are two climate-related impacts to coral reefs). The increasing carbon dioxide levels lead to coral bleaching. This occurs when coral responds to the stress of the temperature warming. This expels the colorful algae that live within most of the coral dies, so the entire ecosystem disappears. Warmer waters are expected to increase the chance of coral diseases such as black band disease, white plague, and white pox. All of the diseases lead to the killing of coral reefs and the entire ecosystem is supports.…

As they have been largely affected by recent developments in climate change and pollution, it is crucial that we stabilize the loss of reefs; if not, we will undoubtedly be negatively impacted. In the event that we lose considerably more reefs, we will also lose a large part of the tourism industry. When you think of tourism, beaches most likely come to mind. Whether it be the pristine waters of the Caribbean, or the rougher waves of the Australian coasts, coral reefs are a popular attraction. Aside from tourism, coral reefs supply, many people with food, as they provide varying species of fish with a food source and shelter. If coral reefs disappear, so do the fish they support with food and shelter, which will add to the world’s existing food challenges. Finally, coral reefs are noted for their biodiversity, which means the undiscovered life living there could possibly a possess cure for cancer or other serious…

Coral reefs are one of the most interesting things on earth. It is a shame that people know so little about them and that they aren’t taken care of near as well as they should be. They are fascinating to learn about if you put time and effort to learn about them and what they are. Also, what they all do for our environment. Our solution for taking care of our reefs are to educate yourself about coral reefs, volunteer for reef clean-ups, do not anchor down on the reefs, and reduce, reuse, and…

One of the most evident examples of climate change seen within nature can be seen the coral reefs. Coral reefs are one of the most divers ecosystems on earth, but are also impacted greatly by climate change. An excellent example of these can be seen by examining the dying coral in Great Barrier Reef. There have been multiple reports on the amount of dead coral, and these reported amounts depend on the regions reported, and vary from 35-93% of the coral is dead. Looking at the entire Great Barrier Reef as an entire system, over 22% of the reef has died, and this percentage is expected to rise further. Marine biologist and climate scientist have nailed down the cause of dying coral reefs to multiple causes, but the two most significant causes have been nailed down to the increase in ocean water temperatures, and the rise of ocean water levels. The NASA data analysis have calculated that global temperatures have increased by a global average of 0.8 ℃ since 1880 resulting in average ocean temperatures to rise. Due to this increase of global temperature, and a change of weather patterns, the polar ice caps have been melting at a rapid rate and have decreased significantly in size. This has caused the average ocean water levels to rise, which in turn increasing the level water above the coral reefs. When the water level increases above the coral reefs, less sunlight makes it down to the coral reef ecosystem. This greatly impacts the coral reef ecosystem, because much of this ecosystem is dependent on sunlight in the form of photosynthesis. Not only does warmer waters directly impact the health of the coral reefs, but it also increases the rate that algae can grow. A common example of rapid growing algae can be seen in the form of Red Tides. Red tides primarily consist of phytoplankton called dinoflagellates, which thrive in warm waters that are rich in nitrogen. These dinoflagellates are known to…

Extinction means that the loss of species or other taxonomic unit occurring when there are no surviving individuals elsewhere. Every species however small may have an important role in maintaining a well-balanced ecosystem. Recent surveys suggest that the number of species in an area may enhance ecosystem productivity and stability; hence the loss of any species could be detrimental to the ecosystem. Direct effects and indirect effects as a result of climate change and perturbations of ocean biogeochemistry have been the major reasons for species extinction. There is evidence that regional ecosystems such as estuaries, coral reefs, and coastal and oceanic fish communities are undergoing rapid losses whether in individuals, whole species or entire functional groups. As a result there was several ways that we can do to protect the marine life from extinction.…
