👉 How? It's simple. On the night of Earth Hour, we'll be posting a must-watch video on all our social media pages - and all you have to do is share it. 

Share it to your Stories or to your wall, re-Tweet it, send it via DM, tag friends in the comments - the choice is yours!

Whether you share it with one person or one hundred, you'll be helping us place the spotlight on our planet, the issues we face, and our place within it all.
