I believe I have an even more valid reason to skip out on the whole lets go swimming in ocean water. I call it “Death by Red Tide”. So what is Red Tide? Red tide is a common name for harmful algae bloom which is primarily found in the Gulf of Mexico. It occurs when colonies of algae (simple ocean plants that live in the sea) grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals and birds.
This report will contain global issues, including the worryingly named “Great Pacific Garbage Patch”, oil spills and local problems, such as the previous near destruction of the Port Noarlunga reef, which, prior to the establishment of the South Australia’s first aquatic reserve, had been overfished and polluted. Although the ocean covers approximately two thirds of the Earth’s surface, it is surprisingly susceptible to human influences. The effects of rubbish dumping and chemical run-off have tainted our oceans and they have taken their toll on the vast marine environments and the populations in which they contain. Circulating the Pacific Ocean is a gyre of marine debris (Non-biodegradable human waste that has collected in marine environments), worryingly named “The Great Pacific Garbage Patch”. Such an entity had been theorised and predicted by oceanographers and climatologists, however, it was discovered by yacht captain, Charles Moore.
He is a consultant for Shark Defense. Shark Defense is a research company developing semiochemical, magnetic, and electrochemical repellents to reduce shark interactions.1 He says that you are more likely to be hit by lightning than to be attacked by a shark.2 Research says that you are more likely to drown in the ocean than to be eaten or killed by a shark. The sea itself is more dangerous that the sharks living in it. So why are people so afraid? Sharks often create images of strong teeth and huge long bodies swimming through the ocean looking for prey.
While bringing it up, it may crush going through all the water pressure levels of the sea.The water pressure is very strong at the bottom of the ocean where ti Titan is placed. If this were to happen what would have been the point of bringing it up? To officially destruct and ruin the past of the Titanic. Not to mention other than destruction and disregard the Titanic its also like stealing from the many people who died there that night. That is now a sacred sea and as we all know, stealing is disrespectful.
In today’s society, the environmental issues that appear on television the most include overpopulation, air pollution, climate change, and water pollution. In this essay, I would like to focus on an aspect of water pollution that has been overlooked by the general public. This lurking environmental danger in the ocean is called a Dead Zone. In Tom Levitt’s article for CNN, Levitt writes: “Aquatic "dead zones" are a tragic illustration of human beings' negative impact on the world's oceans. They are areas so overloaded with pollutants that they have difficulty sustaining any life.” Dead Zones are created by fertilizer and pollution run off from our very own backyards.
Clown fish are so heavily dependent on the reefs due to the fact that the anemone live only in these areas. Increases in the acidity level are another detrimental factor coming from the global climate change. This inhibits the clown fish's ability to detect chemical signals that
Dead fishes could be seen floating on water. Millions of fishes were killed while many varieties such as eels, salmons were even wiped out. This polluted water soon reached the North Sea showing its effect there. The Dutch were mainly worried due to the mercury present in water mixed with other chemicals. A similar incident took place in Japan.
Immature fish in a fish hatchery were reported to have developed respiratory problems and eventually leading them to death. In this experiment we will determine the causes of the fish kill by sampling the water in the lake. The samples will be analyzed for metals, pesticides, and dissolved oxygen. My hypothesis is the fish are dying from a lack of oxygen due to pollution in the water. To get the best results possible, the procedure will be analyzed with three samples.
Toxic waste, poisonous materials such as mercury, dioxin, PCBs, PAHs, and radioactive materials are being released onto our ocean floors causing contamination amongst the plants and animals whom live there. (“Marine Pollution causes and consequences,” 2003) The contamination of these plants and animals steer to health concerns such as lesions on marine life and other major health issues even death. (“Marine Pollution causes and consequences,” 2003) Fujita (2003, p. 4) The contamination of marine life has becoming a major concern for the safety of humans who consume seafood. Toxic waste dissolves into organisms, which are harmful and are passed along the food chain and eventually ending up in our seafood. (“Ocean Pollution,” 2002) This process is called Biomagnification, each time the animals are eaten by another animal the toxins intensify and the levels of toxins increase becoming more and more harmful even deadly for humans.
Oceanic Dead Zones Oceanic dead zones are a serious threat to the Earth and its environment. On shores of every continent and in smaller bodies of water everywhere in the globe they are responsible for the deaths of countless different species of sea life, even though the blame lies with the creators of these dead zones. Places like the Gulf of Mexico, the Black Sea and in most estuaries depositing the wastes of humankind, the lives of aquatic organisms are being put to risk. Pollution and other ways of contamination have turned areas of the Earth’s once beautiful oceans into uninhabitable wastelands. Scientists agreed that these areas are experiencing changes that are absolutely not good for the environments and the creatures living in them.
