Nature is one of our strongest allies against climate change. But we’re losing nature at an unprecedented rate. And we are already seeing how climate change is causing more extreme weather events, such as severe droughts, wildfires and flash floods, which put us all at risk, especially the most vulnerable in our society.

It’s clear: What we do to our planet, we do to ourselves.

But we’re not just living through history right now, we can shape it with every action we take. To stop runaway climate change and shape our future, we must act now.

By signing up today, you’re supporting the move towards a cleaner and brighter future for people and nature and joining millions around the world calling on leaders to secure an ambitious global commitment to reverse nature loss at the Convention on Biological Diversity later this year.

Once you’ve signed up, look out for an email from us. It will contain free goodies such as an Earth Hour-themed Facebook profile pics, stickers for your Instagram stories, plus beautiful nature-inspired wallpaper for your devices so you can inspire others to join the movement. Five lucky Earth Hour supporters will each win WWF Panda Gear to the value of R1000 (T's & C's apply). We hope it’s you!

Closer to Saturday, 26 March, we will send hints and tips on how to use your social influence to amplify Earth Hour on the night. We're not asking for switch-offs, instead we're creating an Earth Hour video for social media, and we want YOU to be in it and help us to share it as we join supporters around the world to create an unmissable Earth Hour experience online.
