Around 150 years ago, humans started releasing fossil fuels into the atmosphere during the industrial revolution. The ocean takes up a quarter of the gas that surrounds earth by absorbing the CO2 we put in our atmosphere. Scientist thought the ocean was a great resource for getting rid of these CO2 gases in the atmosphere; however, they didn’t know how much these gases where destroying our great ocean. NOVA’s documentary presents, Lethal Seas, a documentary of the destruction of our vast ocean, concentrating on the American northwest coast, Papua New Guinea among the volcanic islands of Milne Bay, and Aurora Australis. The documentary dresses the issue of rising acidity levels in the ocean and its effects.
Background: In Ischia Island the water around the island has been acidified for millions of years because of Mt. Vesuvius. This dormant volcano is melting chalk in the sea floor, which releases carbon dioxide into the water acidifying it. This acidification is devastating the life around the island and is still being acidified by the continuous release of CO2. We can use this as an example of what our world might look like if we continue to release carbon dioxide emissions through things such as burning fossil fuels and reducing the carbon banks such by things like deforestation.
Steven Seidman’s Contested Knowledge (fifth edition) is a concise 365-page sociological theory textbook encompassing classical and contemporary sociology. It begins on a personal and autobiographical note in the preface with Seidman describing his emergence from the late sixties as an optimistic and bright-eyed undergraduate. He then expresses concern over witnessing sociological theory being isolated from its public purpose, as he himself felt when struck by the disillusionment of his “sterile and pointless” theoretical work, removed from his “original moral and political motives for becoming a sociologist”. The AIDS crisis in the 1980s shifted Seidman’s focus away from sociology and onto a myriad of other areas: feminism, post-structuralism, race theory and so on. Returning to sociology in later years, Seidman appears to have come to terms with the discipline of sociology, adopting a relativist stance.
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
Several things are at stake from ocean pollution, and there should be a solution. The ocean gets polluted in different types of ways. It can be as innocent as a little kid throwing a water bottle into the sea, all the way to a multi-million dollar company dropping tons of waste into the
Novelist, Eric Schlosser, in his novel, “Fast Food Nation”, expresses how fast food has spread. Schlosser’s purpose is to make us see how addicted we are to fast food. He adopts a shocking tone through the use of diction, Logos, and diction in order to get people to make better choices. For starters, one of the strategies that Schlosser used in this text is diction. Diction can be defined as style of speaking or writing determined by the choice of words by a speaker /writer.
Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life.
About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
One of the biggest cause has been the exhaust gasses. The climate change has some effects on the ocean. One of the most well-known affects would be the melting of ice. Due to the climate change the temperature rises, because of this, masses of glaciers and ice sheets are melting. The melting of the glaciers and the ice sheets brings several affects.
A. There are other ways also that affects the ocean through global warming. Plenty of things that are happening to the ocean are associated to global warming. One important thing is warm water which is caused from global warming and it is harming and killing algae in the
Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity. “ Plastic litter does not degrade, can be expected to last in the oceans for hundreds of years “ ( source 6 ).
Water pollution is a serious issue as not only is water the most precious natural resource, but all sources of water support life that is very necessary for the survival of the planet. Water pollution destroys life and ecology and such damage is irreparable. Those who are still not serious about water pollution must also remember that the pollutants present in water not only destroy the life in the rivers and oceans, but also affect our food chain. Many people have the wrong notion that since they are not disposing the pollutants in the water they are not to blame. These people forget that 70% of the earth is covered by water, and any activity on the land can wash to the seas and oceans.
Now another natural cause of global warming is the rising of the seas. The biggest reason for sea level rising is that global warming is causing the air to be warmer and that 's causing glaciers and ice-caps to melt. Sea level rise would affect about 11 out of the 15 biggest cities in the world. The reason this is happening because gases are being released into the atmosphere which is causing the temperatures to rise, which causes the seas to rise. Sea level rising means more money that we have to spend for people living on the coastlines because coastal populations are growing and people are crowding into coastal areas and that area could be underwater in a few years if sea levels keep rising how they have been.
Causes and consequences The principal reason the ocean is contaminating is because of humankind, such as factories, trash, petroleum, deforestation, and other reasons. Most of our trash is made of plastic, it takes 1000 years to degrade, this material has killed thousands of animals per year, because they get intoxicated or affixed. The glass is another material that can kill animals of the ocean, some fish may get stuck inside the bottle and die because of hunger, others may eat broken glass and bleed out because in damaged its organs.
