When, on this Saturday on 28 March 2009 from 8:30-9:30 pm local time, people around the world switch off the lights, they will be participating in Earth Hour. Created and organized by the World Wildlife Fund, the goal is to raise awareness about the climate crisis and how it's affecting the world we live in. For one hour, with the participation of millions, Earth Hour is an effort to help push critical legislation that pertains to the global climate treaty. This year Human Scale is joining to help the cause as well. Click here for more information about Earth Hour and sign up to be apart of this amazing effort.
