Our environment is facing hugely complex challenges, including declining biodiversity, air pollution and climate change. But we can’t find effective solutions until we understand those complexities.

That’s why Earthwatch is aiming to recruit up to 100,000 volunteers – or ‘Earthwatchers’ – from across the UK and Europe, who will collect scientific data about what’s happening to our natural resources. 

The data our Earthwatchers collect will fill several scientific knowledge gaps, to:

- Help identify which environmental solutions will have the biggest impact

- Help identify how changes at a local level can be scaled up to inform global change

- Indicate where action is most urgently needed.

Anyone can take part, and we offer plenty of guidance on what you’ll need to do when you register.
