Seriously speaking,I didn't give a damn to that kind of stupidly useless campaign.since I don't know how to convey my ideas to others who have done the lights-off , to grumble here is all that i can do .The lights-off campaign was more a show than a collective activity.because as a common sense,we all know that it would be more significant to do what little we can to save energy in our daily life .

Sure,I turned off lights to support Earth Hour, I think it will have great influence to fight the climate change by this activity every year, even though you cann't feel much by turning lights for one hour, but if it can become a global action, it will save a lot of energy and decelerate the speed of global warming, I will continue support this movement and call for more people to take part in it.

Yes,I think it just can make a good example for anybody,but cant make effects actually.

I think it's a stunt. One hour is not sufficient to improve the deteriorated climate.

Yes, i am supporting of earth hour and my opinon is turning off the lights for one hour every day. not every year, because nothing if only one hour every year, just a show.
