Why we must invest in a future free from forever chemicals.
We strongly hope the EU will adopt a comprehensive group-wide restriction on all PFAS, and that the UK will follow suit.

February might feel quiet but for birds, it’s full of action. 🐦✨

Keep a look out for dancing grebes on the water, and your ears open for the drumming of woodpeckers in the woods. 👀🎶

Swipe for what to spot (and where) - then drop a comment and tell us what you’ve seen this month 👇

It’s #WorldWetlandsDay, and we asked what wetlands mean to you.

Your replies were clear and consistent: escape, peace, and room to breathe💚

Unfortunately, people still don’t realise what #HeathrowExpansion actually means. FIVE rivers will be diverted, which is unprecedented. Here’s one of them – the Colne Brook. The M25 and local roads would also be diverted.

Since completing the Gadebridge Park restoration project a fish survey has shown positive improvements in the fish population and the results of a macrophyte survey were equally promising

Immense cost, road chaos thanks to diverting the M25, obliteration of whole villages, irreversible environmental impact. By any measure #Heathrow expansion is a price not worth paying.
