From brown trout becoming “addicted” to methamphetamine to European perch losing their fear of predators due to depression medication, scientists warn that modern pharmaceutical and illegal drug pollution is becoming a growing threat to wildlife.

Drug exposure is causing significant, unexpected changes to some animals’ behaviour and anatomy. Female starlings dosed with antidepressants such as Prozac at concentrations found in sewage waterways become less attractive to potential mates, with male birds behaving more aggressively and singing less to entice them than undosed counterparts.

Fossil fuel firms are biggest beneficiaries of investor-state dispute settlement courts which have awarded $114bn of public money

More than $100bn of public money has been awarded to private investors in investor-state dispute settlement (ISDS) courts, according to the most comprehensive analysis yet.

The controversial arbitration system which allows corporations to sue governments for compensation over decisions they argue affect their profits is largely carried out behind closed doors, with some judgments kept secret. But, according to a global ISDS tracker which launches today, $114bn has so far been paid out of the public purse to investors – about as much as rich nations provided in climate aid in 2022.

A $15bn compensation suit by TC Energy against the US government for cancelling the Keystone XL pipeline which would have carried 830,000 barrels of highly polluting tar sands oil to the US coast every day.
