Perceptions matter. Despite an understanding that chemical pollution can affect wildlife behaviour, respondents from industry were more likely to be negative or neutral in their responses to the application of behavioural toxicology to risk assessment compared to those from academia and government.

‘Biodiversity is not declining’ is a claim you may have heard. But science says otherwise. 📉 The @ipbes.net #GlobalAssessment reveals 1 million plant & animal species are at risk of extinction. Misinformation clouds the crisis. Rely on trusted research to understand our shared challenges. 🌍🧪

"Biodiversity is in crisis" followed by:
"1 million plant and animal species risk extinction
Ecosystems are collapsing
Misinformation slows progress." 
"Trust the science.

To recap: There are 10,000+ PFAS. Some are toxic. They're here forever. They pollute water, air, soils, animals and you. Some linked to diseases inc cancers. So when scientists warn against moves to redefine them, we'd better hope people are listening: www.theguardian.com/environment/...
