The world's geological history is trapped in Antarctica. How is the study of this region useful to us?


Antarctic is totally a mysterious place which can revel past, present and future of our planet. As it was the part of southern supercontinent, Gondawana. Breaking of this mass land gave shape to the earth, it have today. Antarctica act as a mirror to our activities, due to increase in global warming the Glaciers in Antarctica starts melting, due to pollution ozone layer starts. The thick Layers of ice have half a million years old carbon records trapped in it, study of these will revel the past and possible future of the planet.


What are Geoff Green's reasons for including high school students in the Students on ice expedition?


It give them an opportunity to understand the importance of nature for survival of our planet. Also because he wants to offers the future generation of policy-makers a life-changing experience at an age when they’re ready to absorb, learn, and most importantly, take required action.


Take care of small things and the big things will take care of themselves. What is the relevance of this statement in the context of the Antarctic environment?


Antarctica is the best place to understand how taking care of small things will automatically take care of big things. Take the microscopic phytoplankton as example, these grasses of the sea that nourish and sustain the entire Southern Ocean's food chain These single-celled plants use the sun's energy to assimilate carbon and synthesize organic compounds with the help of photosynthesis. Scientists warn that a further depletion in the ozone layer will affect the activities of phytoplankton, as UV rays might destroy them, which in turn will affect the lives of all the marine animals and birds of the region and the global carbon cycle.


Why is Antarctica the place to go, to understand the earth's present, past and the future?
