What is the Marine Ecosystem?
Marine ecosystems are among the largest of Earth's aquatic ecosystems. It covers almost 70% of the earth’s surface. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content.

Why is the Marine Ecosystem important?
Marine ecosystems are very important in to the overall health of both marine and terrestrial environments. According to the World Resources Centre, coastal habitats alone account for approximately 1/3 of all marine biological productivity, and estuarine ecosystems (i.e., salt marshes, sea grasses, mangrove forests) are among the most productive regions on the planet. In addition, other marine ecosystems such as coral reefs provide food and shelter to the highest levels of marine diversity in the world.

Causes of degradation of the Marine Ecology
1) Global warming
2) Acidification of water
3) Pollution
4) Oil spills
5) Marine Fisheries
Acidification of water
Ocean acidification is the name given to the ongoing decrease in the pH of the Earth's oceans, caused by their uptake of anthropogenic carbon dioxide from the atmosphere. Dissolving CO2 in seawater increases the hydrogen ion (H+) concentration in the ocean, and thus decreases ocean pH.
Acidification of water will harm calcareous animals and corals it can cause coral bleaching and can affect the propagation of sound shipping and the noise made by the ships will be louder and will more severely damage the hearing of marine animals such as dolphins, seals and whales.

Pollution
Dumping of untreated sewage into the oceans pollutes it suffocates marine life as non biodegradables like plastic and Styrofoam prevent oxygen from getting dissolved in the water. The fertiliser runoffs from nearby farms and factories promote algal growth which absorbs a lot of dissolved oxygen and minerals from the water. It also

    Ecosystems are the dynamic interactions between plants, animals and microorganisms, and their environment working together as a functional unit. The Great Barrier Reef, an ecosystem that is particularly at risk, is a long, narrow system that stretches for 2000km along the northeast Australian coast. The formation of this ecosystem is attributed to the dynamics of weather and climate, and the geomorphic, hydrologic and Biogeographical processes within the region.…

    An ecosystem is a community of living organisms joined with the non-living components of their environment interacting as a system. Mangroves, Rocky Shores and Sand Dunes may be seen as three independent parts of the ecosystem but if one is disturbed then it affects the other parts of the cycle. There are many examples of ecosystems such as a pond, forest, an estuary, grassland and many more. Hastings Point is an estuary that is continuously threatened by development.…

    The acidity of seawater is determined by the amount of hydrogen ions in solution , which is then measured on the pH scale. The higher the concentration of hydrogen ions in a solution, the lower the pH of the solution. As stated in the previous paragraph, carbonic acid ( CO3-2) releases hydrogen ions ( H+) into the solution. If the sea water absorbs more carbon dioxide and then more carbonic acid will be formed as well. Which means the ocean will releases large quantities of hydrogen ions. Thus lowering the pH of the ocean. “ Ocean acidification: A greater threat than climate change or Overfishing,” reports that since the industrial revolution the pH of the ocean has dropped from 8.2 to 8.1. This change in the pH of water over the past 150 years is the greatest seen over the past several million years. ( Burner W. 2008…

    Ocean acidification is caused by CO2 in the atmosphere when it reacts with water it creates carbonic acid. It's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater. When carbon dioxide is absorbed by seawater a chemical reaction occurs that reduces the seawaters pH, carbonate ion concentration, and saturation states of biologically significant calcium carbonate minerals. It decreases the pH of seawater, meaning it increases the seawater’s acidity. Over the past 250 years, ocean acidity has increased by 30 percent. At least one-quarter of the carbon dioxide CO2 released by burning coal, oil and gas doesn't stay in the air, but instead dissolves…

    An ecosystem is composed of the producers, consumers, decomposers and the living organism that interact and reside in this habitat. They are part of the food web and their roles are important in maintaining the environment. Producers make food, the consumers feed on it but at the same time the decomposers also break down the food to go back to the food web. Mother Nature has assigned different roles (plants and animals) that will sustain our environment and as caretakers we must preserve the ecosystem (no land clearing) so that it will continue to thrive and…

    Oceans, lakes and rivers absorb 30 to 40% of the carbon dioxide produced by the human population. Ocean acidification has been a rising issue for the last three decades, and oceanographers have been studying the carbon dioxide effects on the ocean throughout that time. It is becoming increasingly problematic because the levels of carbon dioxide being emitted into the environment are greater. In the last 200 years, the ocean has become 30% more acidic because as more carbon dioxide is dissolved into the water, the more acidic the water gets. This is destroying the marine life that has had a stable pH level of ocean water for thousands of years. The oysters have been highly affected by the ocean acidification.…

    Ocean acidification is hurting many sea creatures in the ocean. It is also hurting the world food chain. Ocean acidification is when carbon dioxide (Co2) is released into the ocean and the saltwater consumes the Co2. Many creatures have trouble living and reproducing when the ph level is low. It is hurting the world food chain because many people rely on sea creatures for food and if they are slowly dying, there won't be enough food in the world to hold all these people.…

    The ocean is home to many of the most prominent, yet commonly looked over, indicators of anthropogenic climate change present in society today. Often these indicators are in connection with many other obvious, more recognized factors such as the emission of greenhouse gases or the drastic change in global temperatures. More specifically, ocean acidity can be looked at very closely to determine the severity of the situation of climate change, and how it is consistently affecting our planet’s marine ecosystems in a negative manner. Many studies have been conducted throughout the years in order to bring awareness and alert to this situation through the use of facts regarding carefully collected and analyzed data. Ocean acidity may be one of…

    What we could do to prevent ocean acidification from continuing and harming the ecosystems even more is to reduce the world's carbon footprint. Some ideas of helping the reduce the carbon footprint is to use less energy at home; using natural gas and electric heating will reduce your home's carbon footprint, conserving water, reduce using plastic consumption, by less consumable thing’s; the manufacturing of the products create more carbon for making them. The blanket of carbon dioxide we've been building for over a hundred years acts like a greenhouse, trapping more of the sun's heat (Karl, 2009). More heat means a warmer ocean, which is taking a toll on the marine life. This also causes the ocean to become more and more acidic which makes it hard for organisms like corals and clams to build their skeletons and shells. Humans are deeply involved with using energy from fossil fuels. Transport, industry and homes all use fossil fuels. It is hard to get the world to undo what it has became, our imprint on the world will; never go away but we can make changes to prevent it from getting any worse, it is a huge job but working together it can be done (Bijma,…

    Coral reefs are a highly complex and diverse habitat, supporting a wide array of marine species. These particular structures also play an important role in the global economy through their involvement in different industries, especially fishing and tourism. However, over the past several decades, the influx of anthropogenic carbon dioxide (CO₂) as a result of mass fossil fuel combustion has resulted in the global degradation of these economically and ecologically crucial habitats. The key process that has resulted in this extensive damage to coral reefs is termed ocean acidification, which is defined as the increase in oceanic acidity as a result of the uptake of atmospheric CO₂. Over the past 200 years, more than 30% of all CO₂ that has been emitted to the atmosphere as a result of anthropogenic activity has been absorbed by the oceans (Anthony et al. 2008). Such drastic changes in oceanic pH are having multiple adverse impacts upon coral reefs, with many of these effects expected to propagate throughout a multitude of marine taxa.…

    The oceans are one of the most sacred places on this earth, the last mysterious frontier left. They hold millions of different marine animals, and many more that are waiting to be discovered. However, the wide blue waters are beginning to fade fast. Recently, a new pollutant has been exposed, carbon dioxide, is causing this acidification. Ocean acidification is when the saltwater absorbs enough carbon dioxide from the atmosphere that it changes the pH of the water. This is what is happening to the oceans now, and it has monstrous impacts on ocean composition. Ocean acidification has been one of the largest negative impacts on the quality of the ocean, impacting the mortality of marine life, decreasing the economy of commercial fisheries,…
