Composting leftover coffee grounds, eggshells and carrot tops is a way to reduce the amount of food waste that goes into landfills, where it produces the potent greenhouse gas methane.

DoorDash has ripped off more than 260,000 NYC delivery workers. We’re making them pay $131.5 million — the largest worker settlement in City history. This is New York, where hard work pays and greed will cost you.

DoorDash messed up.
They repeatedly left more than 260,000 NYC delivery workers underpaid or paid late, causing them immense stress and financial difficulty.
That's unacceptable.
We've secured a $131.5M settlement from
DoorDash - the largest worker settlement in NYC history and largest delivery worker settlement in
American municipal history.
Every worker will be paid what they are owed, and every company will be forced to abide by the laws of this city.

Beef may be going the way of the internal-combustion engine. Drought, high fuel and feed prices are threatening U.S. beef--an industry that is vulnerable to climate change and a major emitter. Insightful article by @billmckibben.bsky.social @newyorker.com www.newyorker.com/news/the-led...

The True Cost of Beef

Robert F. Kennedy, Jr., eats beef every day, but more Americans, faced with rising prices and another climate warning, might want something else for dinner.

In America, we have no kings, no dictators, no despots, no nobles, no slaves, no serfs, no subjects. Just "We the People." We are not one race, one ethnicity, one religion or one party. But we have one Constitution and one Bill of Rights. Happy Constitution Day, everybody!

The idea that "regenerative" grazing is a climate solution has really taken hold in some quarters. But the science is clear: It doesn't work. Methane and land-use emissions just overwhelm any soil carbon benefits. Here's a great piece by @nicholasdcarter.bsky.social drawdown.org/insights/eig...

Eight reasons regenerative grazing can’t make beef climate-friendly

An influential regenerative grazing movement continues to grow. But here's why the science doesn't back up the purported climate benefits.

Global protein consumption has increased by 1/3 since 1960 More than half of this new growth has come from animal sources, despite plant protein still making up 62% of all protein supply Reversing this trend & being clear on plant protein wins (fibre, planetary health, equal muscle gain) is key

Wow 🤔 Sequestering 1 Gt CO2/yr geologically "would require drilling thousands of wells each year until 2050. For comparison, the total number of active drilling rigs [..] in the US at the end of June 2026 was 581." @arvindpawan1.bsky.social + @hdaigle.bsky.social iopscience.iop.org/article/10.1...
