These superheroes will sweep a wave of darkness across the world

On Saturday, March 29th at 8:30pm local time, millions of people are switching off the lights to join Earth Hour. Use your power to go beyond the hour – check out some of the campaign’s inspiring projects here.

During Earth Hour, be sure to tell World Bank president Kim: Don’t just switch off a bulb, switch off TATA Mundra coal plant. Sign here.

See you under the stars!

Thanks to our friends at WWF.
