The deep sea is so wild. If you told me this was a recreation of the Burgess Shale fauna I would believe it
This is what 9300m looks like in the deep sea. Small, free-moving bristle worms swim through dense fields of slender tube worms. The bristle worms are only a few centimeters long, while the tube worms grow tubes up to 30cm, creating a crowded, living landscape on the deep seafloor.

“The sun’s energy is a gift we have not earned, and yet it comes. That gift of photosynthesis is then shared with others. It’s shared with the larvae of those caterpillars that are eating the leaves…in the abundance of fruits that the [birds] are all coming to feast on.”
Lessons on Scaling Gift Economies—and How It Can Help the Planet - Inside Climate News
Robin Wall Kimmerer, author of “The Serviceberry,” offers ideas rooted in nature for creating sharing economies as a way to bind communities, offer purpose and reduce strain on the Earth.

It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.

There's a trial (of sorts) at 10a ET in Boston today for arguments that NIH unlawfully terminated 100s of grants.
It's a 3 hour hearing and I'll post periodic updates.
Of note: this is the 1st lawsuit filed against the Trump Admin to go to trial.
