Six hundred and fifty million years ago, our globe existed as a giant amalgamated southern supercontinent called, Gondwana, centered roughly around the present-day Antarctica. Things were quite different then: humans hadn’t arrived on the global scene, and the climate was much warmer, hosting a huge variety of flora and fauna. For 500 million years Gondwana thrived, but around the time when the dinosaurs were wiped out and the age of the mammals got under way, the landmass was forced to separate into countries, shaping the globe much as we know it today. Buried underneath layers of ice at Antarctica exist the half-million-year-old carbon records.
If we want to study and examine the Earth’s past, present and future, Antarctica is the place to go. Antarctica is the best place to study the present effects of climatic changes in the world. Similarly, studying the effects of climatic changes at Antarctica, future prognosis about the condition of our environment can easily be made. The prognosis does not augur well. Scientists warn that a further depletion in the ozone layer will affect the activities of phytoplankton, which in turn will affect the lives of all the marine animals and birds of the region, and the global carbon cycle.
