You’ll join millions of others across the world, all taking part in a historic moment. It's your chance to give nature a voice in the nature and climate emergency. You can be part of this, and you can make change happen.
You can take part in the way that most suits you: you can take to the streets and march at an event near you (they're happening all over the UK), or join the digital World Climate March.
If you need a bit more inspiration, watch our video featuring RSPB supporters and staff from across the UK and our CEO Beccy Speight, talking about why they're marching to revive our world.
