Topic:  Geographical features and their location-changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes.

2. What are the environmental issues in Antarctica? Discuss and present the global importance of it.(250 words)

Reference: Physical Geography by Savindra Singh

Why this question:

The question is about the global importance that Antarctica holds for us and the environmental issues concerning it.

Key demand of the question:

Explain the global importance that Antarctica holds for us and the environmental issues concerning it.

Directive:

DiscussThis is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.

Structure of the answer:

Introduction:

Briefly state key facts of Antarctica show the location using a diagram.

Body:

To start with, first quote the environmental concerns in detail –

Antarctica and its surrounding waters are under pressure from a variety of forces that are already transforming the area, scientists warn. The most immediate threats are regional warming, ocean acidification and loss of sea ice, all linked to global levels of carbon dioxide. Although isolated from other continents, Antarctica is connected to the rest of the world through oceanic and atmospheric circulations. Antarctica and the surrounding Southern Ocean are key drivers of Earth’s oceanic and atmospheric systems. The formation and circulation of Southern Ocean water masses provide a key link in the global ‘conveyor belt’ of ocean currents that controls climate by transporting heat and other properties.

For our entire planet, atmospheric pressure, humidity, air temperatures and wind patterns are interconnected and greatly influenced by processes in the Southern Ocean.

Explain the human impact too.

Discuss the importance of it in detail.

Conclusion:

Conclude with the need to save Antarctica with sense of urgency.
