Fining big polluters can reduce environmental damage, but only if the fines match the crimes

Fining big polluters can reduce environmental damage, but only if the fines match the crimes
Fining companies that flout environmental regulations is an effective strategy, if the penalties are severe enough.

Enten: "This is probably the worst 10 day period for the president in the polls his entire second term. The numbers are just atrocious ... when your best poll has you 14 points underwater, you know it's truly bad and it's as bad as 26 points underwater ... -43 with independents! They despise him."

📌 I was in Rome last week to participate in an invited FAO workshop on “Plastics and One Health in Agrifood Systems: Understanding and Managing Risks” followed by my presentation at the PhD Winter School "Sustainable Agrifood Systems and Plastic Pollution: A One Health Vision"

This morning I've already received 3 prospective PhD student requests. I typically receive several per day.

Many applicants are great, but I simply cannot accept them all as I have limited funding and nobody can supervise 500 PhD students, no matter how great they are!!!!

To many marine animals, plastic pollution resembles food. A new study finds seabirds, sea turtles and marine mammals like porpoises, seals and whales don't have to eat much of it for it to be deadly.

Eating just a handful of plastic can be fatal for marine animals, a study finds
Scientists have long known that plastic waste is bad for marine animals. A new study quantifies how little ingested plastic it takes to be a lethal dose.
