Question:

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?

Solution:

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. Scientises warn that a further depletion in the ozone layer will affect the actvities 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.
