Introduction and Problem overview According to Status and Trends of Caribbean Coral Reefs: 1970-2012, a report by the Global Coral Reef Monitoring Network, The International Union for Conservation of Nature, and the United Nations Environment Program, Caribbean coral reefs have been declining at an alarming rate. Specimen populations found in Caribbean coral reefs have been stable for at least 125 thousand years, until the 1980s (Jackson 2001). In this essay, I will focus on the responses and measures taken to combat coral reef degradation. A large focus will be on the loss of grazer species, primarily the parrotfish, as well as global warming. Since the 1970s, coral reef populations have declined by more than 50% (IUCN 2014).
Red Tides affect the marine and land life in various ways, the most important of which are listed below 1. Effects on human life: i. Paralytic Shellfish Poisoning (PSP): This happens if fish contaminated with Alexandrium species is consumed. It majorly affects the nervous system and in many cases leads to paralysis. In extreme cases, the paralyses may affect the respiratory system and ay result in death. ii.
Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas. This industrialization has led to high pollution levels. The pollution that is being emitted daily from the coast lines around South Africa can and is causing damage to the marine ecosystem, such as crippling the fish populations and coral bleaching. It is also ruining the amazing marine biodiversity that South Africa has.
2003a); and many reef fish species in the Caribbean (e.g. Koslow et al. 1988, Sadovy 1994a, Sala et al. 2001). Moreover, Myers and Worm (2005), confirmed a general decline in large predatory fish communities worldwide by at least 90% over the last 50 years - 100 years.
Argumentative Essay Deanna Wood Mrs. Tubergan and Mrs. Rhodes English 6 12 March 2018 Each year sea turtles, such as the Loggerhead Sea Turtles, get closer and closer to extinction because of threats they face every single day. They die from fishing nets, marine debris and oil spills. Loggerhead Turtles will be extinct if we don’t stop causing the harmful threats we are doing. First, oil spills is a big problem in killing our sea turtles. According to Sea Turtles Conservancy there has been a study in 1994 on baby sea turtles, that 63% of all the baby sea turtles had tar inside of their bodies.
There are millions of dolphins out in the oceans and they are declining fast because people couldn’t take another 12 steps to get to the trash cans that are all over the place in cities. Teens are the ones who mostly litter. Kamilo, an island in Hawaii is surrounded by thousands pieces of trash. They now call that place the Great Pacific Garbage Patch. It used to be a beautiful island but is now ruined by trash.
In addition, they are a resource in the development of many medical treatments. “Drugs used to treat asthma, arthritis, and cancer can all be traced to marine sources” (Malizia), so the health of the coral reefs impacts many more than just Hawaiians. With the coral reefs’ many valuable uses, there are also many practices putting them in danger. As reported by prolific science journalist Kendra Pierre-Louis, chemical exposure and runoff are causing an alarming rise in coral bleaching. Bleaching occurs when corals are exposed to water containing toxins, which cause coral reefs to lose their color and also leave them susceptible to death and disease (Pierre-Louis).
Also of the emission of nutrients, the increased use of fertilisers means more nitrates are being washed from the soil and it will go into the rivers and lakes and finally to the ocean. This can cause eutrophication, which is very harmful to marine lives. At the meantime, it will also cause more algae to grow, and the algae will keep absorbing the oxygen and reduce the oxygen level in the water, it will clogs the fish gills and let other marine lives can not breath and asphyxia. People keep destroying the habitat of the animals. And it will disrupt the natural of the entire food chain and finally the whole ecosystem will be unbalance.
Focusing on certain natural phenomena with explanation based on experiment data, natural sciences clearly explain the cause of marine contamination problems. Whereas social sciences use social theories and focus more on broader issues like social phenomena which do not explain clearly about contamination. It is important to do deep research because contamination in water especially in marine ecosystem is a very complex problem. Similar example is from tsunami disaster in Japan in 2011, radioactive which contaminated marine ecosystem is able to enter food chain and to accumulate in animal bodies. If human being consumes these contaminated organisms, toxic compound will be accumulated in human body.
You need a lot of energy to break down the hydrogen bond between water molecules and increase the kinetic energy of particles. This property plays a fundamental role in living organisms. Water cools down and heats up very slowly. Therefore, living organisms can retain heat very well, which ensures that enzymes are working at their optimum temperatures otherwise the enzymes will denature and the organism might die. Moreover, water has a high latent heat of vaporization.
