It was uncomfortably warm yesterday, maybe a small unconscious reminder of the effects and impact of global warming as a result of all the development that has been going on ever since the industrial revolution. According to the radio show I was listening to in the morning, the usage of power (in the form of electricity) seems to be one of the highest contributors to global warming.
So, it was only fair that yesterday people all over the world were urged to turn off the lights (and air-conditioning, or any other electrical appliance) for one hour at 8:00 pm (local time). Some countries which were actively participating even had plans on turning off decorative lights along the streets and buildings, with the hope that at least 1 hour of conserved energy would help make the world a better place.
I was out at 8:00 pm yesterday, but where I was, lights were still brightly lit, and no signs of the air conditioning unit being turned off. Oh well!
