The elevated temperature is the main effect of global warming and the affects branch out from there. Starting with bleaching and algae blooms that make the coral weak with starvation. Then if the lack of nutrients does not kill the coral the acidity of the water will slowly disintegrate the coral. Finally the storms will break up whatever coral remains. This cycle will continue until something is done to stop global warming.
The biggest coral reef in the world which is the Great Barrier Reef has been bleaching quickly and now only seven percent of the reef is left unaffected by ocean acidification and climate change(3). Many scientists believe that corals could become fully extinct by the end of the century if we don’t stop or reduce our carbon dioxide and fossil fuel
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.
Castello Argonese, a tiny island in the Tyrrhenian Sea gives us an enlightening glimpse of Earth in 2100. Chapter six of the book The Sixth Extinction by Elizabeth Kolbert, is solely devoted to her experience in these waters where the vents on the sea floor bubbled up almost 100% carbon dioxide. She talks about the consequences of constantly burning fossil fuels to add about 365 billion metric tons of carbon into the atmosphere and how it could lead to our own demise. The thing about carbon dioxide is that the moment it interacts with water, it becomes an acid which can be deadly to the animals living in these oceans obviously, but also to organisms above sea which includes humans. Elizabeth Kolbert wants us to understand that our actions have tragic consequences and we too will be part of that tragedy if we don’t stop now.
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 high pressure will also distort the biomolecules that are found in species that dwell in low pressure areas. To combat this problem species that live in high pressure areas have adapted to the high pressure with molecules that are resistant to the effects of high pressure. These molecules can be found in structures used in their membrane and in proteins that are required for life. For example some organisms use "piezolytes”. These are small organic molecules that prevent pressure from distorting large biomolecules (Childress et al,
Coral reef systems in the Caribbean are presently stressed due to coral bleaching, overfishing, global climate change, and disruptive algal growth (Wilkinson and Souter 2008). The addition of a piscivorous, predatory invasive species, such as lionfish, will cause permanent damage to that ecosystem. Lionfish have caused a reduction in forage fish biomass, an increase in algal growth due to their removal of herbivorous fish, and an increase in competition with native fish (Morris et al. 2009). Lionfish have few, if any, natural predators due to the presence of venomous dorsal, ventral and anal spines (Halstead et al. 1955). Despite this, Maljković et al.
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
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.
This impacts our well being because, according to the website: The Mekong River- Survival for Millions, the water from rivers are the source of most of our drinking water. Eutrophication causes an abundance of bacteria to form in the river. If there is too much bacteria in the water, it will cause sicknesses and negatively impacts our health. However, if there is too much manure in the water, it will contaminate the water and negatively affect our health as well. This is why we should use animal manure in moderation.
In order for a shell to grow and say alive it needs to combine calcium ions with carbonate ions. However as the oceans become more acidic the carbonate ions, that are found naturally in the seawater, bind more easily with the h+ ions and prevent shell formation. Therefore any aquatic species that rely on carbonate ions to survive find it increasingly more difficult to build or maintain shells since the carbonate ions are neutralizing the h+(acid) before they have the chance to combine with the calcium ions. 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
In conclusion tanning may be very popular and fashionable, but it poses numerous internal threats and external health threats. With the information about the threats, we need to put a stop to tanning and preserve our natural beauty. External threats such as malignant melanoma and other types of skin cancers, wrinkles, sunburn, and skin aging. These effects are very dangerous on the skin and can be avoided if the effects are known before the damage is already done. The internal health problems ruin the immune system, making it harder to fight skin cancer and other diseases.
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.
Growing up, I often found inspiration snorkeling in the Florida Keys. Each trip, I entered an ever-changing resilient ecosystem of vibrant, vivacious sea life. However, in recent years, nonnative lionfish have invaded the entire East Coast devastating our coral reefs. Because they have no natural predators in the Atlantic Ocean, lionfish have almost completely depleted our oceans of juvenile fish, creating a major food shortage for native fish. If no action is taken, the future of our coral reefs over the next 50 years looks alarmingly grim
