If the planet was to lose all the coral in the world, it would decrease the diversity of the ocean (Casper 184). Plus, the destruction of reefs affect other animals such as reef fish, turtles, and sharks (Casper 185). All this is happening due to global warming. How does global warming affect coral? Global warming has and is still negatively affecting coral due to the rising temperature of the ocean.
I choose this article because I think it’s really cool that we are finding ways to repair the coral reefs. The coral reefs are already in danger of extinction because of global warming, so finding a way to try and repair them is great. Ever since the Industrial revolution, the oceans have been taking in more carbon dioxide. The quantities of the gas taken in by the oceans are large enough that now some areas of the oceans have become more acidic, a phenomenon called ocean acidification. Ocean acidification is harming many groups of animals, including coral reefs.
As observations were conducted on multiple reefs, however, a major decline in the water quality and coral coverage of reefs worldwide had declined dramatically. It was upon these observations that the reefs ability to self sustain was questioned (P. Harris, 2012). Their structure is resilient to most natural disturbances, however, they are extremely vulnerable to human interference such as the nutrient contamination of their water quality that has occurred. The contamination this study focuses on is as a result of fertiliser and other nutrient rich pollution which have contaminated these coral sanctuaries. This contamination has lead to great loss of coral coverage.
Understanding the Problem at Hand: Coral Reefs It is important for people worldwide to learn of the importance of the coral reefs and of the negative effects that unrestricted tourism and global warming have been causing to them. To clearly see the big picture, one must first go back to see the early roots of the problem. Coral reefs have been being mapped out as early as some of the first maritime sailors, and soon turned out to be a huge destination for tourism. Unregulated tourism is almost always bad, and this turned out to be the case for the coral reefs as well. Once it became apparent that the coral reefs were decreasing at an extremely high rate, governments and scientists finally did something right by regulating tourism attempting to save the once great coral reefs.
Calculations for tourism for the year of 2015 are unavailable at this time, but for the year of 2014, the reef received a total of 2.19 million visitors. It is a well – known piece of information that there is a global climate change going on where there is a rise in CO2 in the atmosphere due to higher emissions of fossil fuel and more deforestation occurring. The ocean then absorbs more of this CO2, which in turn raises the acidity, which in turn creates a poor environment for the coral to live and recover from bleaching that has already occurred. This change in acidity also affects the calcium carbonate that corals use to build themselves. (“Climate Hot Map- Global Warming Effects Around the
Ocean acidification is affecting marine life immensely. When our oceans keep acidifying it causes carbonate ions to be less plentiful and these ions are an important part for marine life such as oysters, clams, sea urchins, and corals to get there structures built and maintained such as their shells and coral skeletons(1). Ocean acidification can also affect some fish 's ability to detect predators putting them at a greater risk and causing the entire food web to be in danger(1). The organisms that are having the most trouble adapting to rising acidity is corals because they produce calcium carbonate to make their rocky outer layer that forms coral reefs(2). Coral reefs are the beautiful ecosystems that are booming with life but since the acidity has been rising and so has the overall temperature of the ocean the coral has been bleaching and has not been able to grow well or even stay alive(2).
Shark finning majorly affects the oceanic environment’s plant life and its food chain. Although there are opposing views on the criminalising of this horrendous practice. The practice of shark finning has majorly affected the plant life within the oceanic environments containing a low population of sharks. With the dramatically decreasing numbers in shark’s population, the health of the ocean’s plant
Chemicals from industries and agricultural sites can run-off into the ocean. When the toxic chemicals from this and sewage get into the ocean’s ecosystem; it leads to reduction in oxygen levels, decay of oceanic plant life, and severe decline of the quality of the sea water. Toxic chemicals that get into the ocean raise the temperature drastically, this is known as thermal pollution. Marine animals that cannot survive in these higher temperatures will eventually
The usage of plastic emits between 100-500 million tons of CO2 every year. (Staley, 2009). We could reduce carbon dioxide emissions if we stopped the production of plastic as it would be much safer for the environment. The use of plastics can have major effects on our world, and we should stop using
The lack of proper reporting of overfishing in freshwater has lead it to not being regarded as a bigger crisis than it actually is because more focus is on marine life. Overfishing in Saltwater Due to the fact the majority of the earth’s surface is covered in salt water (oceans) this has lead to many people to see it as a good source of food from the fish that is available but its fast becoming a crisis as it has lead to overfishing. According to marine ecologist, overfishing is the greatest threat to ocean ecosystem today. This has increased over the years because the fishing effort has been greater. This has been brought about because of the following; • The structure of the ship has increased and nets are bigger and can go deeper in the ocean.
As you can see, all the CO2 emissions that we produce are theoretically decreasing the oceans biodiversity and this can be a threat to some aquatic animals. Now we can get to the main disadvantage, which is the threat of the aquatic animals
You all have been hearing don’t pollute your whole life, but it still happens. Pollution is a huge problem especially in the ocean, the ocean plays a vital role to our survival and with all polluting it, it causes problems for us in the long run. Pollution causes a lot of damage to the ecosystems that live in the ocean and the ocean itself. When the oil spill happened in the Gulf of Mexico that was a bad disaster, that was man made that hurt an ecosystem in ocean. All that oil spread throughout the ocean causing a lack of sunlight to penetrate through the water deep making it hard for plants to grow and or prosper.
A decrease in tourism lowers revenue in a certain the area, and threatens economies that are increasingly dependent on their local tourism. Commercial fisheries are threatened because acidification harms calcifying organisms which form the base of the Arctic food webs. pteropods and brittle stars both from the base of the Arctic food webs and are both seriously damaged from acidification. Pteropods shells dissolve with increasing acidification and the brittle stars lose muscle mass when re-growing appendages. This problem is so detrimental because if not solved, can eliminate species of marine life from different parts of the globe, and can possibly create an ocean in which is not safe for any living being.
It’s not realistic because by doing that they’re exposing millions of people to the harmful toxins of the lake beds of the Sea and endangering wildlife. Accelerating the drying process is the last thing we need. Also, there is not enough funds for the long-term restoration of the Sea. The Salton Sea Task Force’s recommendation is to restore between 9,000 and 12,000 acres of shoreline habitat by 2020 using available state funds. Their plan is realistic because it involves using many the state has, which makes it a more obtainable goal in the long
