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.

The Forum will examine how scientific innovation, traditional knowledge, emerging regulatory and policy measures, corporate accountability and multi-actor engagement can deliver practical and lasting solutions.

Looking forward to participating as an invited panelist next week in Montreal in this Public Forum: Regenerating North America’s Future ⬇️

📌 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.

Ciao, ciao Rome!
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."

Finally arrived at the UN 🇺🇳 FAO.

Roaming around #Rome (Cont’d).

Visited the Vatican, Pantheon, Colosseum, Castel Sant’ Angelo, Fort Ramano and the UNFAO HQ.

Hi Paul, I always have aspirations to do a part run on these international trips. But then I realise my flights arrive on Saturday afternoon and leave Saturday morning. Damn! The good news is I got plenty of steps in today.

Having lunch outside the United Nations 🇺🇳 Food and Agriculture Organization.

Seems appropriate.

When in #Rome!

I was astonished to learn that primary microplastics -- themselves a pollutant -- are used to treat wastewater. And of course, once in the water, some of them are released into the environment. www.theguardian.com/environment/...

“This is the worst microplastic spill we’ve seen this year,” says environmentalist Joshua Beech. Worse even than the spill of nurdles (pre-production plastic pellets) in March, when two ships collided in the North Sea.
