This is glorious. The billionaires thought their power was so limitless they could just bulldoze the will of the people, and they didn't even bother trying to buy off politicians. Just asserted that they were going to do a thing and then the county and the people said fuck all the way off.

Too much of a good thing is usually bad. Put too much phosphorus in the water, you'd get eutrophication, and anoxia, and if you push that to the extremes, it might be part of a mass extinction event. 🧪⚒️ Link: www.nature.com/articles/s41467-026-…
a Before LOME, weathering drew down atmospheric CO2 levels and cooled the climate prior to the Hirnantian. b A change in ocean anoxia and/or cooling triggered the initial extinction pulse LOME 1. c An increase in continental P delivery to the oceans increased primary productivity, increasing dissolved oxygen demand and drawing down atmospheric CO2 levels. Cooling and ocean anoxia resulted in widespread extinction. d Declining marine P levels reduced dissolved oxygen water column demand from decomposing primary productivity, and post-glacial warming allowed ecosystem recovery. e Before the LDME, the water column was mostly oxygenated under a greenhouse climate. f An increase in continental P delivery to the oceans increased primary productivity, increasing dissolved oxygen demand and drawing down atmospheric CO2 levels. Cooling and ocean anoxia resulted in widespread extinction. g A reduction in marine P supply decreased P-driven productivity and reduced the extent of marine anoxia. h A second surge of P to marine environments increases the extent of marine anoxia and draws down atmospheric CO2, culminating in global cooling, which together delayed ecosystem recovery.

Things you learn in an elevator: In Switzerland, it is illegal to own a single guinea pig because these animals need social interaction.
An elevator screen with a black frame displays trivia in French about guinea pig ownership. The blue screen shows a clock in the top-left corner set to 13:52 and a date of 03/10/2026. Next to this is French text that reads "En Suisse, il est illégal de posséder un seul cochon d'Inde car ces animaux ont besoin d'interaction sociale." (which translates to: "In Switzerland, it is illegal to own a single guinea pig because these animals need social interaction."). Below the time is a large blue panel with white text, "RC," which means "Rez-de-Chaussée" or ground floor, with a downward-pointing arrow and a small circle with a line through it. An illustration below the French text depicts three reddish-brown, white, and black guinea pigs grouped together over a bowl against an orange background, with a dark branch with leaves on the right.
