If I was putting on a Climate Week food event about good farming practices, I personally would opt to not have it cosponsored by a company that was found to raise animals in unspeakably cruel conditions. But maybe that's just me.

New episode! @marisul.bsky.social dismantles the animal industry's favorite defense — that cruelty is fine as long as someone else is crueler. From foie gras to factory farms, it's a frustrating ride. 😤 Listen on your fav podcatcher, watch on our YouTube, or check out ourhenhouse.org/ep983

URGENT: Big Oil is pushing our planet to the limit and needs to be held accountable for the devastation it wreaks for profit. But two new bills could give the industry full legal immunity — and they're being voted on TOMORROW. If passed, they'll then go to the House for consideration.

ICYMI: Wyoming’s wolf hunting season begins tomorrow, putting Mollie’s Pack and other Yellowstone wolves at risk of being killed by trophy hunters the moment they cross the invisible boundary of the park.
A text block centered over a blurred background. The text is a quote from Kristine Akland, our Northern Rockies director. It reads "Yellowstone’s longest continuously existing wolf family could be dead within weeks if Wyoming doesn’t step up to protect them. Mollie’s Pack has been studied by scientists and enjoyed by visitors for decades. It would be a massive loss for Wyoming and the millions of Yellowstone visitors if Wyoming Game and Fish let them be killed this hunting season."

Something strange about humans is that we are more likely to act if we feel we can solve more of the problem. In activism, this sometimes means making a problem FEEL smaller in order to keep larger groups of people working on it.
