How Humans Have Affedted the Antartic Food Web

The global mean surface temperature is projected to increase by around 0.3 to 4.8 degrees Celsius above the pre-industrial values by the end of the 21th century. Therefore, if we continue to not check the anthropogenic emissions, the increase may be around 8 to 10 degrees Celsius, which is incredibly damaging to various ecosystems internationally. It is difficult to determine the possible aftereffects of the ice sheets melting because the equilibrium-response timescales of them is longer than both the atmosphere and ocean. The ice-sheet/ice-shelf model shows that if the atmospheric warming increases 1.5 to 2 degrees Celsius above the present temperatures, the Antarctic ice shelves will collapse and trigger a centennial scale response –a never-ending

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

Hundreds of algae species are scattered across the land, as well as around 100 species of linchen, 350 species of moss, and 2 grass species. The subantarctic islands surrounding Antarctica have a wider range of plants. About 45 bird species populate the area south of the Antarctica Convergence, and a few penguins and petrels actually live on the continent. The waters surrounding Antarctica are full of seabirds, fish, seals, and whales.

(c) The past events from Easter Island has help indicate environmental issues on earth today by showing that the environmental scientists believe that there are more limits adding on to resources that are already hard to get today. Resources like clean air and water, nutritious foods and other resources that our environment provides. Also, they believe that the earth will no longer be able to maintain a stable climate.

The author of “The Last Wilderness Preserve” has a stronger, negative opinion about how human behavior affects antarctica's economy using diction and other word choice to display these negative emotions in quotes such as, “scientific explorations can be done more easily in other locations, and those in antarctica threaten the natural state of the land.”and also, “...Humans have still contributed to massive problems there (Antarctica) Global warming, a gradual heating of the planet thought to be caused by pollution, has melted most of Antarctica's ancient ice and may soon lead

The Last Wilderness Preserve and A New Land of Opportunity present different arguments about the impact of human action on Antarctica, and lead to different conclusions about how to treat it. Kendra Washington, author of The Last Wilderness Preserve, believes that human interference in Antarctica can cause and worsen many environmental issues. She claims that the continent was able to maintain its natural state due to the limited amount of human interaction, and should be left alone. On the other hand, Michael Serillo, author of The New Land of Opportunity, believes that human action in Antarctica would bring about many scientific advancements, and can even help protect it. He claims that the beauty and resources that can be found in Antarctica are reason enough to take as much advantage of the land as possible. Kendra Washington’s argument is more effective, as she takes the environmental and social consequences into greater

Kathy Conlan is an expert in understanding the weird and wonderful world of marine creatures that live deep under the Arctic ice. She specializes in marine benthic biology and amphipod systematics. Kathy studies how human and natural changes affect marine life in the Arctic and Antarctic, the effects of pollution on marine life as well as global warming. She is past chief officer for Life Sciences in the Scientific Committee on Antarctic Research (SCAR) and is a judge for SCAR’s Martha T. Muse Prize for Science and policy in Antarctica, represents Canada for the Canadian Committee on Antarctic Research, taught at Huntsman Marine Science Centre and Students On Ice, mentors university students and gives speaches and “Show and tells” at the museum.

Many people have different views about preserving Antarctica. Some people may view Antarctica as a scared environment and that it should not be destroyed by destructive human greed as the author states in “The Last Wilderness Preserve.” Others may view Antarctica as a wonderland that is the key to all the questions many ask about this world. The author’s claim in “A New Land of Opportunity.” However you feel about the topic it is clear that the author in”The Last Wilderness Preserve” supports his argument better and has the stronger argument.

Antarctica is a cold, frozen, and mostly empty land found at the South Pole of the earth. Humans go there mostly for research and occasional tourism, though it's incredibly inhospitable, especially in the colder months. Due to the harsh environment, it remains the last true wilderness on earth and is protected by an international agreement called the Antarctic Treaty of 1961. In this Treaty, world leaders agreed that everywhere south of 60° south latitude would remain unclaimable by any country. The treaty says that it cannot be used in military reasons, or to dispose of radioactive waste - only peaceful

The Great Barrier Reef is slowly dying sometimes because of humans. The species of animals and plants and in danger. Some of the factors that are causing it to die can’t be stopped like natural disasters. But the pollution can be prevented. The Great Barrier Reef is the biggest reef in the world and we need to protect it from dying

In the video Let's Save the Last Pristine Continent, Robert Swan paints a vivid picture of global warming and its affects on Antarctica. One of the major problems he discusses is that due to the fact of the hole in the ozone there is what they call an ice melt. This is where pieces of ice the size of small nations are breaking off and melting. It is believed that this will cause the ocean to rise by 1 meter over the next hundred years. Mr. Swan believes that if we learn to use more renewable energy along with managing our energy we may slow down and even possibly stop the ice melt. This video has shown me the importance of recycling and conserving energy. This is not an issue that can be stopped by one person, it will take all of us to make

There are possible solutions to climate change and its effects on Antarctica but if not taken there will be grave consequences of inaction. A solution to climate change is reducing our greenhouse gas emissions. A solution to climate change is reducing our dependency on fossil fuels. Another possible solution is to start more green initiatives. Corn

Ocean pollution is one of the most urgent issues in our world today. The ocean is crucial to our ecosystem and it is being severely damaged at an alarmingly increasing rate. In this paper I will educate about the role the ocean plays in our beautiful Earth, why it is being so widely ignored and dismissed, the causes of pollution, and its effects on animals and humans alike.

It was Mihaljo Mesarovic, the author of “Mankind at the Turning Point”, who once said “The Earth has cancer and the cancer is man”. He was definitely onto something. In fact, humans have had a major negative impact on the world’s marine environment. Throughout recent human history, it has been obvious that the wellbeing of the marine environment has been in jeopardy. Pollution of the ocean, overfishing and the greenhouse gases these are all the aspects that can cause the destroying of the precious environments, such as reefs, sea-grass and coastal habitats. According to the essay and interview “Seafarming at the End of the World”, written by Peter Meehan, he presents the fact that human impact on the ocean is the main reason that causes the awful situation of marine ecosystem and organisms.
