Welcome to the Earth Hour global community!

To celebrate Earth Hour, Dr. Seuss’ legendary character The Lorax has promised to turn his moustache green for a whole day on 31 March.

According to The Lorax, “Unless someone like you cares a whole awful lot, nothing is going to get better. It's not,” so now is your chance to do something. If 500 children promise to switch their lights off for Earth Hour, The Lorax will turn his moustache green for a whole day on 31 March.

To take part in The Lorax’s challenge for Earth Hour visit www.youtube.com/earthhour (with Mum or Dad’s permission) and click on the link to “Accept” the challenge. Then make sure you turn out your lights at 8:30pm on Saturday 31 March. Don’t forget to buy a few candles or have a torch handy… or you may find yourself in the dark!
