While all of us cannot be as enterprising as Felix Finkbeiner, the 13-year-old German school boy that has spearheaded a global eco campaign, we can still help reverse global warming trends with small things - Like switching off all lights and electronic devices for an hour, which is what hundreds of millions of people all over the world are planning to do from 8.30-9.30 on Saturday, March 23rd, in celebration of Earth Hour. Believe it or not, this minor action will go a long way in helping global warming.
