Lsn3 Should Antarctica Be DevelopedPresentation Transcript
Should Antarctica be developed? To understand the arguments for and against developing Antarctica
What does Antarctica offer?
Lots of wildlife, including penguins, seals and whales
Minerals are stored under the ice sheets which are 3 miles thick in places
A unique holiday experience
A supply of Krill and fish
A natural landscape mostly untouched bu humans
Rank these factors in order of importance! 1 being most important
Antarctica has important minerals stored under the ice that we may need to use in future, like oil, gold and coal
It contains 75% of the Earths fresh water
It reflects heat energy from the sun back into space and thus reduces global warming!
Its waters contain massive stocks of Krill which may be the answer to global food shortages
Its ice can be tested to show past levels of global pollution
It is the only natural landscape left in the world
It could be the safest place to dump nuclear waste as it is away from humans
It is the only place where certain penguins, whales and seals can live. Without it these animals would be lost!!!!
Why is Antarctica important?
You can only find scenery like this in Antarctica
Where else can you find a glacier this big?
Where else can you have 24 hours of day light for one month of the year?
We are the most dangerous seals on Earth, we have our home here!
We live on Antarctica- aren’t we cute!
We rely on Antarctica to breed!!
Humans disturb our home, they affect our breeding and they bring strange things and watch us!!!! Humans are taking my fish food from the ocean, what if they take it all?
Krill- food for the animals! Future food for us?
Krill is abundant in Antarctica, but all other animals in the region eat them, as other species die they are getting eaten!
Some people think Krill will soon be the only sea creature left for us to eat- as we are over fishing other fish species like cod!
Antarctica should be left as it is ‘the world’s last wilderness

There may be oil supplies under the Ice, we are short of oil so why not use it? Oil prices are rising, if there is oil there we should use it to lower the price There could be other minerals under the ice that would be useful to us!
This is our planet we have the right to go wherever we want on it Tourism can make money to invest in Earth
Tourist operators are beginning to tap into the huge demand to visit the last great wilderness on Earth. If people visit the Antarctic as tourists they will tell others about its beauty and will urge people to keep it as it is Antarctic is amazing! We need to keep it as it is, there’s nowhere else on Earth like it
People will cause pollution of noise, disrupting wildlife The ice caps will be melted by over use Humans have destroyed everything else on Earth, why should we destroy the one ‘free’ place left? Wildlife is unique- should be kept that waygay Environmental impacts kept to minimum nothing is left their or taken from it Tourists will educate others Only 100 people at one time, so controlled access Negative Positive Leave as it is for everyone The more people visit the more people will go and cause disruption Wildlife is disrupted by people and may be extinct if too many people visit It’s the only place unaffected by humans Only place where you can here NOTHING- SILENCE! Tourism makes money If people visit they will spread the word of how precious it is and they will want to keep it as it is Minerals can be used to make money What is the use of leaving it doing nothing? Against For developing
You have learnt that Antarctica is a wilderness and that there are lots of ways it could be used in the future.
There are lots of groups interested in using Antarctica in different ways in the future
We want things left as nature intended I think we should learn all we can from the Antarctic Ice We need all the fish we can get!!!!!
In your group you have 15 minutes to prepare a speech and poster to put forward your opinion of what should happen to the Antarctic in future.
Your speech should last no longer than 3 minutes and be persuasive
During the presentations you should fill in your table.
Circle whether the group presenting are for or against developing the Antarctic
Fill in 3 arguments highlighted by each group of people
Using the sheet you have been add to your table explaining whether each interest group is for or against developing Antarctica
Fill in the 3 reasons on your table to show whether that group thinks developing Antarctica id s good or bad
Should Antarctica be developed?- the decision
Yes, fully exploited
No, not at all
Which of the above do you agree with?
Write detailed answers
in your book
Write up an A4 sheet of paper in preparation for an assessment next lesson- you will be allowed that paper and no extra resources in the assessment.
Use the help sheet that I have given you and the things written in your book from the last 3 lessons.
Add as much as you can to the paper so that you have it to use in the assessment
