WATER

NONFISHERIES PRODUCTS:
• Salts (table salt)- is an ionic compound composed of one atom of sodium (Naˉ) and one atom of chlorine (Cl+) which is responsible in the salinity of seawater.

• (Naˉ) + (Cl+) = NaCl (table salt)
• Water- is composed of two atoms of hydrogen (Hˉ) and one atoms of oxygen (O+) bind together by hydrogen bond. • 2(Hˉ) + 1(O+) = H2O

SALT





30% of the world’s supply sea salt is extracted and refined to produce table salt. processed commercially
Provides flavor to our daily meal.

WATER
• Sea provide vast reservoir of water when salt is removed.
• It can be used in irrigations
• Provide us a potable water
DESALINATION- process of removing salt from the sea water to produced water.

MINERAL
RESOURCES

    It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas. This can take up to thousands of years to form and if humans use too much oil we will have to wait another thousand years to use the oil the ocean provides us with.…

    Many people think that fisherman is one of the most male dominated, most dangerous professions and not suite for woman. However, Linda Greenlaw, the captain of the Hannah Boden, has proved herself that female can be a fisherman. She breaks the beliefs and superstitious that women are “Jonahs” (bad luck aboard boats) and also make the world realized that gender discrimination does not play a part on her career. As for being female, she says, "it hasn't been a big deal. I never anticipated problems stemming from being female…I have been surprised…by the number of people who are genuinely amazed that a woman might be capable of running a fishing boat. Frankly, I'm amazed that they're amazed" (58). As being a captain and had been fishing professionally for 15 years, Linda faced many obstacles and problems which forcing her to make good decisions in order to ensure the survival of the boat and reach her ultimate goal, which is to catch as many fish as possible, since the more fish she catches the more money she make. Sword fishing is not easy and very challenge for her. She has to use many supervision and leadership skills to manage the boat, crews and fishing during the month of the trip. Especially dealing with crew problems, she has to solve them as soon as possible in order to maintain her rule and teamwork, which is very important to make her trip run smoothly and reach her ultimate goal. However, even though Greenlaw did not expect of what will happen with her crew during offshore but she has proved herself that she has an ability to cope with them in the effective and efficiency way. Therefore, showing she has capability to cope with crew problems and maintain teamwork among of crews, there are some significant troubles that challenge Greenlaw, which are a striking her irresponsible crew, racial problem between her crewmember and the health problem of her 40-year-old crew.…

    Plastic is one of the resources that is polluting our environment. Some scientist believe that the more plastic added to the ocean the more harmful it is for the organism in the ocean. According to Tobias Kukulka, a physical oceanographer by University of Delaware stated in, Plastic below the Ocean Surface, "You have stuff that's potentially poisonous in the ocean and there is some indication that it's harmful to the environment, but scientists don't really understand the scope of this problem yet." Meaning that the more plastic put into the ocean it becomes more fragile it get and drift to the surface the birds, fish, or even other wildlife animals mistaken these plastic as food.…

    Plastic in the Ocean

    Pacific Ocean Plastic Waste Dump that I found most interesting was that “This mass of plastic is slowly being broken down into a plastic dust that marine wildlife mistake for food. Small fish consume tiny bits of plastic as if they were normal plankton. Those fish are then consumed by larger species and the plastic contamination moves up the food chain” [ (Fitzgerald) ]. I will admit that I have been to the ocean on numerous times and I have watched waves carry out plastic bottles, sandwich bags and other plastic based items. Some of the items that have washed away have been my own. I never really thought much of until today. While on vacation, I also enjoy dining out on seafood. The thought that I could potentially be feeding my daughter and my family potentially harmful food due to plastic contamination from my lack of knowledge and understanding is very disturbing to me. As Kristen E. Silven states in her article Plastic Contamination in the Atlantic Ocean, plastics contain chemicals that are slowly released in to the waters and atmospheres, which the fish will end up breathing in and contaminating themselves, fishermen then catch these fish and the contamination ends up back in the human food chain. I have been told throughout my life to limit my intake of tuna due to the high levels of mercury that are found in tuna. In a study conducted by Marcus Eriksen and Anna Cummins during the Algalita Marine Research Foundation’s 2008 voyage across the North Pacific, they found that 35% of the 671 lantern fish had plastic particles in their stomachs. Lantern fish are the primary food source for Salmon, Tuna, Mahi Mahi and other fish commonly eaten by humans [ (Boyle) ]. This will increase the possibility of ingesting toxic chemicals such as BPA, Phthalates and the oily toxins that the plastic is able to absorb (such as partially burned carbons) due to plastic being oliophillic. I know that after reading and researching this topic, this year on vacation, I will make…

    It is true, it is merciless, literally; it’s not conscious, so it has no feelings, no remorse, no pity, no awareness. It would be wrong to say it is inanimate, because it is certainly animate. And not alive, yet contains so much life within it might as well be. Like a Frankenstein body filled with cells and bacteria and nerve impulses yet no consciousness.…

    Oceans cover two thirds of our planet thus they can be regarded as one of the major factors in shaping this blue marble in space. But oceans just don’t result in varying gradient of humidity that gives rise to different vegetations and ultimately widely different biomes when coupled with other factors such as differential exposure to solar radiation, and inherent soil type. Oceans are living systems that themselves support numerous life forms whether plant or animal; whether microscopic phytoplankton or the gigantic mammals like whales. There are gradients in oceans too whether it is in terms of productivity, density, salinity or in terms of nutrient composition. While coral reefs have one of the highest productivity open oceans have one of the lowest of all biomes. Now since nutrient composition and productivity varies there must be mechanisms similar to nutrient recycling on land that enables continued growth and productivity.…

    The mass killings of elephants for their ivory, the widespread pollution across the ocean, and the careless behavior towards nature are all things that people are contributing to. Mary Kate Frank, the author of both “Saving the World’s Ocean” and “The Race to Save the Elephants” believes that people’s lack of respect towards the elephants and the ocean is resulting in negative effects to the U.S and other diverse nations, such as a dramatic drop in trade and transportation, and an economic breakdown. Although some people are trying to overcome this hindrance such as the U.S and China, there are other obstacles blocking the way. The aftermath of all of this is the ocean life and wildlife dying because of the copious amounts of greed filling…

    Marine Ecosystem

    • 1619 Words
    • 5 Pages

    The earth's oceans provide an enormous range of resources and affect the quality of life as we know it. The oceans cover approximately 70 percent of the surface of the earth and have a cyclical effect on weather, e.g. temperature, precipitation and air quality. Regardless of your views on global warming, the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence, emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create novel challenges for coastal and marine ecosystems that are already stressed from human development, land-use change, environmental pollution, and over-fishing. (Eileen Claussen, 2002)Ocean and coastal marine systems are also affected by changes in climate, through increases or decreases in water levels. When water levels are altered naturally or unnaturally, nutrients and oxygen levels vital to the maintenance of marine organisms, are changed. A myriad of marine species including some birds, are impacted by the availability of marine food sources and will have long term implications regarding freshwater and seafood supply for humans as well as animals.…

    b) Fog harvesting may be considered to be an appropriate technology for a poor rural community because it is cheap to install and maintain. Also, repairs can be fixed easily by little experienced people. The main advantage of the project is that the technology does not require any electrical energy which means it is environmentally healthy and the people or the government do not have to pay any money to run the technology. The technology can be created with little money as well which means the LEDC government do not have to spend lots of money to create the fog harvesting.…
