"Earth Hour is more than just switching off the lights." Too true, as this video shows. A lot has happened in the past year to put our planet's health at the forefront of many people's minds, from crazy weather to the wild success of Blue Planet II.
The WWF's annual event will take place from 8.30pm to 9.30pm local time on Saturday March 24th, with #Connect2Earth this year's theme. Simply turn off your lights and devices for an hour and reflect, or go out there and celebrate. Music, stargazing, parties – they're all happening.
