...220 Coral Reefs vs. Climate Change Corals reefs around the world have been fighting climate change for just over two centuries. This problem hasn’t caught much attention to the average human eye, but it’s about time everybody realizes how this is affecting their everyday lives as well. Coral bleaching is one of the main concerns with coral reefs around the world. Coral bleaching can be fatal to coral reefs, which in return could hurt us in the future. Ocean acidification is another problem that coral reefs are facing around the world. Not only is it harmful to the coral reefs but harmful to marine life as well. Although these are all negative actions towards coral reefs there can be a bright...

...Marine conservation From Wikipedia, the free encyclopedia Coral reefs have a great amount of biodiversity. Marine conservation, also known as marine resources conservation, is the protection and preservation of ecosystems in oceans and seas. Marine conservation focuses on limiting human-caused damage to marine ecosystems, and on restoring damaged marine ecosystems. Marine conservation also focuses on preserving vulnerable marine species. Contents 1 Overview 2 Coral reefs 3 Human impact 4 Techniques 5 Technology and halfway technology 6 Laws and treaties 7 Organizations and education 8 References 8.1 Notes 8.2 Bibliography 9 External links Overview Marine conservation is the study of conserving physical and biological marine resources and ecosystem functions. This is a relatively new discipline. Marine conservationists rely on a combination of scientific principles derived from marine biology, oceanography, and fisheries science, as well as on human factors such as demand for marine resources and marine law, economics and policy in order to determine how to best protect and conserve marine species and ecosystems. Marine conservation can be seen as subdiscipline of conservation biology. Coral reefs Coral reefs are the epicenter for immense amounts of biodiversity, and are a key player in the survival of an entire ecosystem. They provide various marine animals with food, protection, and shelter which...

...Water Resources - Overfishing Science 275 3/2/10 Kenneth Whitehall Water Resources - Overfishing In recent decades the method and technologies involved in commercial fishing has advanced tremendously. With a limited time in the fishing seasons, fisheries are forced to catch as many fish as they can as fast as they can. This, along with the growing population of people and their appetites for fish, is causing a major problem with overfishing. Overfishing is the process of catching fish faster then they can reproduce. It is fishing that unsustainably depletes fish stocks or that damages the ocean environment. Overfishing is causing irreversible negative effects within the ocean waters of the earth. Every living thing plays its part in the entire food chain from the smallest of organisms to the largest of animal. From the bottom of the food chain to the top all species are both predator and prey. Every living thing is connected in some fashion and relies on each other to complete the circle of life. When a part of this circle is either in shortage or is missing altogether, there is a break in the chain and everything pays the price in the end. Overfishing has become a major problem in recent decades. The damage that overfishing has already caused in the oceans is still often a surprise to environmental experts. Globally, 90% of large fish are already gone (Festa, Regas, & Boomhower, 2008). As the fishing stocks slowly disappear, commercial fisheries are starting...

...on earth for future generations. Therefore it is important to understand how climate change works, what is causing the climate to change, what effects these changes are having, and how they may continue to affect the global environment. What causes the environments on earth unable to support life? What can be done about these predictions of climates in the future? How will these climate changes affect South-West Western Australia? How does climate change work? Climate change is a natural process that has been functioning on earth for billions of years, it is the regulator of the earth's abililty to support life by the cycles of The Greenhouse Effect. The Greenhouse Effect has made the earth an environment for supporting life through the cycling of energy from the sun via short-wave radiation, which heats the earths surface, then is released into the atmopshere as long-wave radiation. This cycle is made possible by the prescence of Greenhouse gases, which redside in the earths atmopshere, and absorb most of the long-wave radiation given off by the earth, with the remainder being expelled into space. This process cycles the heat from the sun around the earths atmosphere and a climate is the result, without this circulation of energy life cannot exist. Greenhouse gasses absorb long-wave solar radiation, enabling the Greenhouse Effect. The main gasses are Water Vapour H2O (clouds), Carbon Dioxide CO2, Methane CH4 and Nitrous Oxide, with water vapour being the most abundant...

...The Coral Reefs Ecosystem Hidden beneath the ocean water, is the coral reefs team of life. Fish, corals, lobsters, clams, sponges, seahorses, sea turtles are only a few of hundreds of thousands of creatures that rely on reefs for their survival. I think that coral reefs are beautiful and I find that ecosystem of a reef is fascinating. Despite the fact that Corals look like rock or plants they are definitely marine animals. Corals life begins in tropical water as floating larvae. After a short period of time the larvae attaches itself to a hard surface and becomes a polyp. Corals are related to the jellyfish some people say that a coral looks like a jelly fish upside down due to a coral having a lot of tiny polyps. A single coral polyp may be as large as a saucer or small as the top of a pinhead. There are billions of polyps working together in a cooperative colony. Generation after generation creating a limestone skeleton that forms the framework of the beautiful coral reefs. Coral Reefs grow very slowly. It could take up to a hundred years for a reef to grow 3ft. (Best&Bornbusch, 2001) Coral Reefs have been in existence for over 215 million years and located in tropical waters. The earths ocean floors cover more than 70% of our planet's surface and 97% of that water is found in the ocean. As everyone knows ocean water is salty and the reason being is due to the salinity in the water. The two ions found in seawater are chloride and sodium. The salt in the ocean's water has...

...The causes and consequences of the enhanced greenhouse effect and global climate change Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg Figure [ 1 ] - The greenhouse effect diagram, http://www.ozcoasts.gov.au/indicators/images/oze_fs_009_02.jpg “The unprecedented increases in greenhouse gas concentrations, together with other human influences on climate over the past century and those anticipated for the future, constitute a real basis for concern” (American Geophysical Union, 2014). The Earth's surface temperature has to be just right for humans, not too cold and not too hot. Thanks to the natural greenhouse effect, which has kept the Earth warm. It’s a phenomenon where the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface. As there are naturally occurring greenhouse gases in the atmosphere that help keep the Earth warm, added amounts of these gases leads to extra heat being trapped in the Earth’s atmosphere. These gases (carbon dioxide, methane etc.) are being added by human activities and are enhancing the greenhouse effect as shown in figure 1. The global climate change is causing many environmental consequences and will cause more. There are five gases that contribute to the enhanced greenhouse effect. These five...

...of carbon in the upper photic zone followed by the downward flux, through the water column, of dissolved material. The oceans absorb carbon dioxide (CO2) from the atmosphere by photosynthetic assimilation. Ultimately this assimilated carbon is transported to depth, down through the aphotic zone, as particulate matter sinks to the depths. Although a considerable amount of organic matter, which is produced is respired though metabolic activity. Biology, physics and gravity interact to pump organic carbon into the deep sea. The processes of fixation of inorganic carbon in organic matter during photosynthesis,...

...(Kolieb, Huelsenbeck, & Selz, 2010). It does not matter how big or small the organism is, ocean acidification is a threat on all marine life. Direct effects include the inability to strengthen the shells of animals such as crabs, shellfish, clams and many more. The increase in acidity is also leading to the reduction of certain fish being able to breathe. (Kolieb, Huelsenbeck, & Selz, 2010). "These direct and indirect impacts could all result in animals becoming less fit to survive which could lead to population level consequences and ripple effects throughout marine ecosystems." (Kolieb, Huelsenbeck, & Selz, 2010). At one point it was considered that fish were not affected by ocean acidification. They thought that fish were resistant to acidification effects. Research later showed that these fish are actually becoming more overwhelmed by these rising acidic levels. (Kolieb, Huelsenbeck, & Selz, 2010). Our human population is also suffering the effects of ocean acidification. Ocean acidification is affecting not only our production and intake of these goods but also the decline in revenue for fish farmers. "Some 500 million people worldwide depend on reefs for coastal protection, food and income; economists value reefs at between 30 to 172 billion dollars per year. "(Kolieb, Huelsenbeck, & Selz,...

The chemical is linked to disorders such as migraine headaches, Alzheimer's disease, loss of appetite control, obesity and many other serious health conditions. Describe the impact on earths systems. It does not necessarily have an impact on the systems as much as it has an impact on our whole population. If we don't try to take a stand on the issue they will continue to poison our meat.

...where the majority of the energy finally escapes moves higher, these higher levels are much colder and so they do not radiate heat very well. The rate that radiation escapes to space is lower, and the planet will take in more than it radiates. As the higher levels emit some of the excess radiation downwards, the lower levels will warm all the way down to the surface. The imbalance will remain until the higher levels get hot enough to radiate as much energy back out as the planet is receiving. Though all natural processes, they are not always helpful. On the other side of the spectrum, we as humans are not always helpful to the processes. Because of this, we find ourselves at a time of question. What are we doing to our planet and how will it affect us? Many are attempting to take action now, others try to not believe. Eventually, however, we are all going to see what we have truly been doing. Global warming is possibly the most debated topic today, but it is also the biggest problem our world faces today. Our ignorant way of living has now become harmful to the only earth we have to live on. Although some may not see the effects now, to many this problem is surreal. Multiple species of animals have been endangered by the effects of global warming. This problem not only limits the life of...

...the largest active carbon sinks, absorbing up to 30% of anthropogenic carbon dioxide (CO2) produced (Sabine et al., 2004). Anthropogenic CO2 absorbed by oceans form carbonic acid, which dissociates to produce hydrogen ions. This has alleviated the impacts of global warming to an extent. However, human activities such as burning fossil fuels and urbanisation have caused ocean acidity to increase by 26 % from preindustrial levels till today. (IPCC, 2014). Being terrestrial creatures, our focuses are on environmental impacts occurring on land, and less so in oceans. Yet, oceans are so fundamentally important that ignoring...

...2014 Tami McConnell Ocean Resources Paper (Option 2) Our oceans are at a greater risk than ever for acidification, dying coral reefs, over fishing, mercury pollution, litter, and trash you can actual see floating from space, and so much more. The oceans are our biggest resource for living, for life on Earth… they supply us with our air in every breath we take. Oceans gives us 50% to 70% of our air!! They need our help if we want to continue the joys of salt life and watching our fellow salt-water friends swim about happily. * Describe the problem and how it came about I would like to discuss acidification and the harms of it. I didn’t know that much about this problem before going into all the research, I knew our oceans we in dire need of help, but I had no idea how bad the acidification has gotten. Ocean acidification is when carbon dioxide (CO2) is absorbed by seawater and those chemical reactions that occur reduce the seawater pH, carbonate ion concentration, and saturation states of biologically important calcium carbonate minerals (NOAA, 2014). Our carbon footprint is killing not only the oceans animals, but we are killing ourselves here. Acidification is especially harmful to the little plankton, oysters, and shellfish. It’s harmful to the coral and the star fish that attach themselves to the coral, the fish that swim in the reefs, sea otters, and even the whales until eventually it finds its way right back to us on our dinner tables. Oceans supply a lot of...
