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.

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.

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.

Microplastics Could be Fueling Heart Disease?

New study out of @UCRiverside

#Microplastics #health

Everyday microplastics could be fueling heart disease

Microplastics—tiny particles now found in food, water, air, and even human tissues—may directly accelerate artery-clogging disease, and new research shows the danger may be far greater for males. In mice, environmentally realistic doses of microplastics dramatically worsened plaque buildup, altered key vascular cells, and activated harmful genes linked to inflammation and atherosclerosis, all without changes to weight or cholesterol.

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."

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.

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/...
