WWF’s Earth Hour is a global annual event where hundreds of millions of people switch off their lights for one hour to show they care about our planet. It takes place this Saturday, 28th March.
It’s about people from across the globe coming together to create a symbolic and spectacular lights out display and asking for change.
It happens every year between 8.30 and 9.30pm, with switch offs starting in Samoa and finishing in Tahiti.
It’s been growing every year, with more and more countries and people signing up – last year an all-time record with 162 countries took part.
