- 2. Why is Antarcticaa significant environment? • The Antarctic continent is a land mass covered with ice up to 13,000ft (4km) thick. There is some exposed rock and the only plants are very small mosses and lichens (although it was once heavily vegetated – millions of years ago). Antarctica is the highest, driest, windiest, coldest continent in the world. http://www.adventure-network.com/antarctic-environment Antarctica can be used to study what these conditions do to things like animals and plants. This means that it is very unique.
- 3. Why is Antarcticaa significant environment? Antarctica is used for studying what is happening to the Earth Antarctica is important for science because of its profound effect on the Earth's climate and ocean systems. The Antarctic has a crucial role to play in our understanding of global climate change. http://www.wwf.org.au/our_work/saving_the_natural_world/oceans_and_marine/priority_ocean_places/antarctica_and_southern_ocean/ http://www.skwirk.com/p-c_s-1_u-21_t-188_c-603/significance/nsw/significance/current-issues-antarctica/what-is-antarctica- The environment of Antarctica is significant because it has been changed very little by people. Scientists can study the area to find out how an environment evolves naturally without human interference. Scientists can use Antarctica to to see how the Earth would naturally evolve without human interference.
- 4. Why is Antarcticaa significant environment? This is a image of Antarctica with dots showing where people have interfered the land, this shows that Antarctica has only been interfered with very little and is very natural making it significant.
- 5. What impact dopeople have on this environment? Some Antarctic species have been taken to the verge of extinction for economic benefit. Others have been killed incidentally or disturbed, soils have been contaminated, untreated sewage has been discharged into the sea and rubbish that will not decompose or break down for hundreds of years has been left behind in even the remotest parts. http://www.coolantarctica.com/Antarctica%20fact%20file/science/human_impact_on_antarctica.php Humans have had a great effect on Antarctica because of it being different than the continents that we live on. People have brought their habits to Antarctica and it has disturbed it a lot. http://www.coolantarctica.com/Antarctica%20fact%20file/science/threats_tourism.php Invasive species - accidentally bringing in insects or seeds. Impact on breeding birds - being made anxious by an influx of people that may cause them to abandon their nest. Erosion or disturbance of fragile environments - many feet walking over the same piece of ground and routes will leave paths. Oil spills from ships and boats - there may be a spill due to rupturing a holding tank, or if the vessel sinks, all the polluting fluids will eventually escape. People have effected Antarctica by accident or not knowingly, but it has still had a big impact on the environment and the animals.
- 6. What impact dopeople have on this environment? This cartoon shows that people have altered the lives of the animals and environment in a bad way. It shows that people only get to see the best of Antarctica and it is quite often different to reality. http://www.sarahs-travel-blog.com/antarctica_ss/penguin_cartoon.jpg
- 7. What impact dopeople have on this environment? From 1996 an environmental team whose main goal was the repairing of fuel tanks and buildings, dismantling of old buildings and equipment, removal of dumps and cleaning up of the territory. Within the span of six years the station and territory adjacent were cleaned up and the waste was prepared for the removal. RESULTS OF THE WASTE DISPOSAL PROJECT AT BELLINGSHAUSEN STATION (work book) Although Antarctica has had a bad environment due to rubbish, people are trying to make it better by collecting and removing rubbish from Antarctica. This image shows the amount of rubbish in Antarctica. You can also see that the seal is trapped in the rubbish, this shows that it can effect the animals. http://totaraciaran.weebly.com/uploads/2/5/2/0/25203875/539232996.jpg
- 8. Is the globalcommunity doing enough to make sure that this area is sustainable? Twelve countries were original signatories to the Antarctic Treaty in 1959. Of these, seven claim territory in Antarctica (claimants). The Treaty entered into force on 23 June 1961. Since then, 40 other countries have acceded to the Treaty, for a total of 52 Parties. http://www.antarctica.gov.au/law-and-treaty/treaty-partners This shows that people are becoming more interested in Antarctica. The Parties know that Antarctica is very important and can contribute to science and other learning fields.s People have become more aware of the effects that we have on Antarctica and now we protect Antarctica through the treaty. Over the years since the Antarctic Treaty came into force in 1961, ever greater environmental awareness has led to increasing regulation by the Antarctic Treaty System. All plants and animals in Antarctica are now protected and there are measures in place to prevent pollution of this the worlds most pristine environment. http://www.coolantarctica.com/Antarctica%20fact%20file/science/conservation.php
- 9. Is the globalcommunity doing enough to make sure that this area is sustainable? In 1991 the fear that distemper from dogs could spread to seals led to a new clause in the Antarctic Treaty. "Dogs shall not be introduced onto land or ice shelves and dogs currently in those areas shall be removed by April 1st 1994” - and so they were removed, there are now no dogs or domestic animals of any kind in Antarctica. Dogs are no longer being introduced into Antarctica. This is probably so that they don't hunt endangered animals or spread diseases. This image is of some of the members of the Antarctic Treaty, They have shown up in Antarctica and placed their countries flags to show their interest in Antarctica. http://www.coolantarctica.com/Antarctica%20fact%20file/science/conservation.php http://www.anta.canterbury.ac.nz/resources/images/treatyl.jpg
- 10. Is the globalcommunity doing enough to make sure that the Antarctic env I believe that the global community is doing enough to make sure that Antarctica is a sustainable environment. My evidence for this opinion is that the global community has put in place many clean up projects. Through the Antartic Treaty (1961) there are now restrictions on who can go to Antartica, what can be taken there and how rubbish is disposed of. "Within the span of six years the station and territory adjacent were cleaned up and the waste was prepared for the removal." The Treaty signed by 52 parties is always being updated as we learn more about Antartica and our effects on it. An example of this was the ruling that dogs would not be allowed in Antarctica as they could spread distemper. "Dogs shall not be introduced onto land or ice shelves and dogs currently in those areas shall be removed by April 1st 1994”. I believe we are a generation that is more aware of the damage we are doing to the planet and are aware of how unique Antartica is. It can be used scientifically to study global warming. Because of its remoteness it can remain clean and untouched by rubbish.
- 11. Evaluation of collectingand the annotation information Research aspect: Which two sources of information were the most helpful and give reason why? The two sources that were the most helpful were coolantarctica.com and antarctica.gov.au. The website coolantarctica.com had a lot of information about antarctica, it was easy to access and had a lot of source material. The website antarctica.gov.au had a lot of information about the Antarctic Treaty and what is happening in Antarctica. Which type of sources did you not use – give a clear reason. I tried not to use sources that were not to the point or were hard to understand. I widths so that I could make good annotations that were accurate. Were there some sources which showed bias? ( good or bad viewpoints expressed that are based on the interest group that presents the source material) Most of the information was just facts so they were neutral but some of the websites sounded a bit bias and would only talk about bad facts or good facts.
- 12. Evaluation of collectingand the annotation information Annotating the resources chosen Did you find the process of annotation easy or difficult? Why? I believe that it was quite easy because it was just reading the information and explaining how you read it and what it means to you. Did the example of the annotated work help with the annotation process. No, I already knew how to annotate from history class, but it was good to have an example of the work that we had to do. Improvements: Would you change your approach to researching and collecting info.? How? Maybe, by searching with quotes e.g “Antarctica is significant because”.
