The theme for this year’s celebration of World Environment Day is ‘Only One Earth.’ This was also the slogan for the 1972 conference in Stockholm which led to the birth of the annual global event on June 5. The theme underscores the fact that out of all the galaxies, star systems, and planets are known, only Earth sustains life. Since human actions are causing irreversible damage to our environment, there is an urgent need to minimize or prevent further damage to our biosphere.
