Explanation:

1. Humans, who are known to have existed for a mere 12000 years, have caused tremendous impact and played HAVOC with nature.

Population explosion, PUTTING a strain on available resources, carbon EMISSIONS, fossil fuels and global warming have all resulted in climatic and ecological imbalances that have also affected Antarctica.

2. Antarctica, though unpopulated, has been affected and there are concerns for its half a million year old carbon records trapped under its ice sheets.

3. The ‘Students on Ice’ programme, an initiative of Canadian ADVENTURE educator, Geoff Green takes students on expeditions to Antarctica, to create awareness in them, the future policy makers.

4. The stark proof of global warming and environmental threats helps students attain an understanding of ecosystems and BIODIVERSITY of our planet.

5. An amazing display of the food chain of the Southern Ocean helps in the understanding that further depletion of the ozone layer, will set off a chain reaction that will affect the global carbon cycle.

6. The simple truth is, take care of the small things and the bigger ones will automatically be taken care of.
