Earth Hour  is a worldwide awareness event organized by the World Wide Fund for Nature (WWF) and it is held on the last Saturday of March annually. On this day households and businesses are requested to turn off their non-essential lights for one hour to raise awareness about climate change. More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011 and this year many more cities like Dhaka, Bangladesh , will be joining.
South Asia is a region with many developing countries hungry for power. Millions of people in the Indian sub-continent have no access to electricity, and the power sector is plagued by corruption and inefficiency. The demand is much bigger than supply so many countries use load shedding  (planned rolling blackouts) to manage the electricity distribution.
In countries like Nepal, Pakistan and Bangladesh daily there are 4-12 hours of load shedding varying on the situation everyday. Netizens are vocal on the issue of observing earth hour in the social media. While some are requesting others to observe Earth Hour, some are thinking that this is not more than a joke. The following tweets from the region reflect what they have in mind.
@KaziAhadKader  (Kazi A. Kader): “@dailystarnews Bangladesh for the first time tonight will observe Earth Hour…” We were doing that long before it had such a fancy name.
@shuvo666  (Shuvo Rashid): No wonder #Bangladesh is one of the most environment conscious countries in the world. We celebrate Earth Hour every day, 12 times! #Blackout

@Mahamali05  (Maham Ali) Is Pakistan also supposed to observe Earth Hour? We already observe Earth Hour at least 6-8 hours a day everyday.
Speak For Change  writes in a blog post:
Earth Hour is a serious issue and one must not write against it. Is it a bigger issue than load-shedding that we experience daily in all parts of the country? Is it a bigger problem than the losses in millions we attain due to the absence of electricity to the industries? Is it more serious an issue than the non-availability of electricity in a local hospital where patients are operated upon under standby generators because the electricity doesn’t show up? I don’t think it is more serious than countless scenarios like these, because it is not for us, people living in third world countries.
