Earth Hour will be celebrated around the World on Saturday March 29th, 8.30pm until 9.30pm local time.
Run by WWF the Earth Hour has encouraged many countries, cities and towns to take part and show their support, by fund raising or by awareness activities. Iconic landmarks and businesses on the Earth will be going dark for 60 minutes.
As an individual you can also take part by simply turning off your lights for one hour along with hundreds and thousands of others, making a symbolic gesture of awareness of how we can make a difference to protect our planet.
