Not many years ago when global warming issues were in their infancy, it was generally presumed that the environment activists had the responsibility to deal with them. Not anymore! Time has come when each one of us has to become an environmental activist to save and nurture our planet if we want to leave something for our future generations. Ecological imbalance, climate change, global warming and carbon emissions are issues that have set the alarm bells ringing. This is a fact which was acknowledged by the assembly of world leaders in Copenhagen last month to seek lasting solutions. Global warming has become global warning for India.
