Join people and businesses around the world who are turning out their lights for one hour at 8:30 pm on March 28 and taking action against climate change.

Earth Hour not only turns global attention to the need to find solutions to climate change, it also demonstrates the power that each of us has to make a difference in the future of the planet.

Go dark and show your concern for our living planet while sending a strong message to our leaders that we must act now to slow climate change.
