Every year hundreds of millions of people around the world in more than 7000 cities in over 180 countries take part in this amazing global conservation movement. People do a wide range of things around the hour to show they care about our planet’s future. Millions choose to mark Earth Hour by going ‘lights out’ for 60 minutes at 8.30pm – a symbolic show of solidarity. To find out how you can take part in Earth Hour, whether you’re an individual, school or business go to the Earth Hour website.
