The stunning underwater world that’s at risk as the Iran war drags on | CNN Not far from the vessels stuck in the Persian Gulf is a one-of-a-kind marine ecosystem that’s home to dolphins, sea turtles and coral. How do oil slicks affect them?

A wildlife disaster unfolds alongside the human tragedy in the Strait of Hormuz

@greenpeace.org reports Iranian vessel Shahid Bagheri, stuck by a US warplane in early March, is still leaking oil near the Strait, with nearby wetlands at risk:

there's a quote in this piece where the headmaster argues that the kitchen *has* to make money and rails against the 'nanny state'

not necessarily blaming individual institutions or people, but this doesn't seem a great situation

‘No cheeseburgers … they would go bankrupt’: pupils reject plan to cut fatty foods from lunch menus Though welcomed by chefs and campaigners, many schools say the government’s plan to remove ‘grab and go’ options from the menu is a step too far

the issue seems to be that contracting private companies creates a profit motive, and profits are highest for (ultra)processed and unhealthy foods

I get that schools face financial pressure, but they also have a responsibility to create an enabling and healthy environment for children

back on the plastics archive research and the first hit is a 1977 Washington Post article on Coca-Cola funding a shrimp farm that claimed to have bypassed the need for fresh water

both really weird and an example of how alert corporations were to environmental concerns like water stewardship

niche complaint, but it's incredibly irritating that some video editor has put a wilhelm scream in the UEFA 'football for all' campaign, and also that nobody has bothered to fix it

an interesting example of what Adam Hanieh argues (contra much of the financialisation literature) is the inextricable relationship between oil futures markets and the physical production and delivery of oil

Iran war puts focus on petrochemicals used in numerous products and a driver of climate change The Iran war is highlighting global dependence on petrochemicals. The oil- and gas-based chemicals are used in products from plastics to fertilizers.

as @dlevialvares.bsky.social and @tris-sia.bsky.social point out in this report, plastics continue to a blindspot in coverage of the current conflict

a plausible scenario is that demand destruction for oil + gas in energy systems leads to even more aggressive expansion into petrochemicals

we argue that plastics are integral to ultra-processed foods as a globalized product - while this might seem obvious, it is one that is rarely made in either the environmental politics or food systems literature

Ultra-processed foods are a key driver of the global plastics pollution crisis - Nature Food The plastic waste generated by ultra-processed foods (UPFs) is a key driver of the global plastics crisis. Recognizing the integral role of plastics in UPF production is essential to developing a more socio-ecological perspective on these food products. This Comment identifies the linkages between the rise of UPFs and the rise of plastic packaging, calling for a renewed research agenda.

Braskem have already increased plastic resin prices, so I reckon a matter of time before others manufacturers do so.

this has gone under the radar, but this crisis has also caused a global spike in the cost of plastic, which seems almost certain to increase the cost of food

similar to energy we need to defossilize food systems, reducing dependence on single-use plastics, shifting to more sustainable reuse models

The war in Iran could trigger a global food shock
• More than 1.1mn tonnes of fertiliser and fertiliser inputs is currently stuck in the Gulf
• Shortages are starting during northern hemisphere’s planting season, raising the risk of lower harvests for staples like rice
