Saturday night, March 28, you can turn off your lights from 8:30 to 9:30 PM and join the thousands of cities, tens of thousands of businesses and millions of people in 84 countries who are “voting” to show their concern about climate change.

Earth Hour a simple but dramatic way in which you can participate. Help mobilize governments around the globe (including your own) to get to work on solving this impending disaster.

Or you can go ahead and buy a rowboat to leave in your front yard. Just in case.
