Seaweed is mucking up beaches. This robot could stop it — and fight climate change – NPR

In shallow waters, sargassum can smother coral reefs and alter the water’s pH balance, killing off local seagrasses and mangroves. It can choke boat motors, constricting local fishing yields if not cutting off whole marinas. Sargassum once clogged a desalination plant so badly that residents of the U.S. Virgin Islands were told the drinking water may not be safe…
Road Hazard: Evidence Mounts on Toxic Pollution from Tires – Yale Environment 360

Researchers are only beginning to uncover the toxic cocktail of chemicals, microplastics, and heavy metals hidden in car and truck tires. But experts say these tire emissions are a significant source of air and water pollution and may be affecting humans as well as wildlife…
Don’t look away: This book is a wake-up call to our ‘monstrous’ waste crisis and how to solve it – EuroNews

I’m only three pages into Wasteland when a stat first unnerves me: “It is forecast that by 2050 we will be producing a further 1.3 billion tonnes [of waste] a year.”
It already feels like the world is weighed down with waste. And I’d (somewhat naively) hoped that, given today’s talk of sustainability, recyclable materials and circular economies, we’d be headed the other way by 2050 – towards a less wasteful world…
‘Plastic air pollution’: Microplastics in clouds could be exacerbating climate change – EuroNews

Researchers found several types of polymers and rubber in the water in cloud water surrounding Mount Fuji, Japan’s biggest mountain, and Mount Ōyama.
Their study, published in the journal Environmental Chemical Letters, joins a growing body of evidence showing that plastic pollution has infiltrated most ecosystems on Earth…
It’s Not Just Coral. Extreme Heat is Weakening Entire Marine Ecosystems in Florida – Grist Magazine

Anemones, sponges, and jellyfish are bleaching throughout the Everglades amid record temperatures. It’s a troubling sign for Florida Bay and beyond.
We studied more than 1,500 coastal ecosystems – they will drown if we let the world warm above 2℃ – the Conversation

Much of the world’s natural coastline is protected by living habitats, most notably mangroves in warmer waters and tidal marshes closer to the poles. These ecosystems support fisheries and wildlife, absorb the impact of crashing waves and clean up pollutants. But these vital services are threatened by global warming and rising sea levels…
The Straw That Hijacked the Plastic Pollution Movement – Hakai Magazine

Plastic straws used to be “environmental enemy number one.” Was the fight against them in vain?
One way to save coral reefs? Deep freeze them for the future – NPR

Ocean temperatures have been extremely hot this summer, wreaking havoc on some of the world’s highly vulnerable coral reefs. With marine heat waves only expected to get worse as the climate changes, scientists are increasingly focusing on an emergency plan: collecting coral specimens and safeguarding them onshore….
Alarming’ scale of marine sand dredging laid bare by new data platform – the Guardian

One million lorries of sand a day are being extracted from the world’s oceans, posing a “significant” threat to marine life and coastal communities facing rising sea levels and storms, according to the first-ever global data platform to monitor the industry….
