Came across this refreshing piece of news that the city of Sidney in a symbolic gesture had switched off its lights for an hour to raise awareness about global warming. Although an hour of switched lights will in no way save the environment it will go a long way to trigger a thousand ideas on how to conserve energy. After banning incandescent light bulbs this is the second big step Australia has taken. Living in India teaches one a very important lesson that resources are always limited and should be utilized carefully without wastage. Just doing small things like switching off your lights before going out, using fluorescent lights instead of incandescent, putting your laptop to sleep when not in use are just small steps which when added together might go on to make a huge difference. We all need to care a little bit and make a big difference.
