I wrote and posted this to Instagram a couple of days ago and it became my most-read poem ever. I’m honored I get to feel big feelings alongside you all. I’m posting it here too and want to use this space more consistently. Hello friends ❤️

I'm not convinced Canada learned anything from Canada, actually...

Consumers urged to ‘completely avoid’ UK-caught cod as population plunges Marine Conservation Society warns that fish numbers have reached dangerous point of decline

Obviously did not learn anything from Canada: complete collapse of northern cod in 1992, billions in compensation, major job losses, cod stock still have not recovered. Weirdly, it is never presented as a cost of not using ecology to drive policy. www.theguardian.com/environment/...

An absolutely *adorable* little bee 😍 for your morning

Today, the emperor penguin has moved from Near Threatened to Endangered on the @sscmarine.bsky.social IUCN Red List of Threatened Species.

From the makers of Drakkar Noir comes their new scent, Dunning-Kruger.

An unwitting blend of malevolence and insecurity, Dunning-Kruger intoxicates with shades of bluster and boondoggle; while offering up hints of flop sweat and vulgarity.

Existential, civilization-level threats this morning. And if that's not enough for you, here's an extra reminder that we need to continue to wean ourselves off of fossil fuels. The sooner, the better. 🌍

My favorite from "No Kings" in Denver.

Massive budget cuts for US science proposed again by Trump administration Budget proposal would also curb federal payments for scientific publishing.

The administration's budget request would cut research funding for the National Science Foundation and the Environmental Protection Agency by more than 50%.

It's hard to imagine an external enemy causing more long-term damage to this country.
