i just hope people continue to remember the environment after the world env. day, it often happens that we raise a hue and cry about it on one day, then go about our own business unmindful of the issue the next.
simple things that all of us can do are to take public transport, dont waste paper, water or actually anything that we have cause every commodity is linked with our environment....
Its called a 'carbon footprint' that we need to minimize.
