I think being skeptical about this kind of event is a very negative attitude. The organization (WWF) is certainly aware of the fact that 1 hour can’t save the planet. It is a purely symbolic event, to make the world aware of this big problem that concerns all of us. We should all continue try to stop or control all kinds of waste and pollution (energy, material, forests, sea, air). This event is a good way to try to reach other people. But above all, I think it is a good way to unite all citizens from the world to act together and show the politicians that we want a change for the climate and for the planet. They can create the needed legislation for all kinds of industry.

It won't do much in saving electricity or reducing carbon emission but it's a great way to send the message to all the people and hopefully have them make their first step.

I think it's a good means to create awareness, but then who isn't aware of global environmental issues by now? There needs to be more initiatives to get people to constantly protect the environment rather than for 1 hour on 1 night of the year.

It is up to individuals and businesses to participate. If Shanghai can turn its lights out in the CBD at 7pm daily, a lot of other cities in the world could too.

I dont think Earth Hour really works, it only reachs the people who are already aware of these issues and besides that this one hour wont change anything by itself. I wont participate because I wouldnt know what to do from 8-9pm in the evening without light / TV / computer etc.
