Landing in North Dakota and most of these points of light out the window are not a house or a building but an open flame, burning 24/7. We’ve set the land on fire.

I wrote this nearly 11,000 word deeply researched essay about the history of natural heritage in Indiana, the mind-boggling scale of vibrant biodiversity we've lost, and the lies we've told and continue to tell ourselves to cover it up. zacharyammerman.substack.com/p/once-and-f...

Thundering herds, skies gone dark, an inland sea of wetlands, and forests unfathomable to the modern imagination

Indiana’s Grand Kankakee Marsh — once one of the largest wetlands on the continent, rivalling the Everglades. It was drained starting in the 1850s and was basically entirely lost to agriculture by 1920.

Indiana was once more than 80% covered by woods, with its 20 million acres of primeval forest nearly long enough to encircle the globe one and a quarter times in a mile-wide band; early Europeans arriving in the region that would later become our state described a realm of forests without end,

ndiana's Buffalo Trace! An ancient buffalo highway that cut a deep path into the land from the prairies of Illinois to the grasslands of Kentucky, cutting across the thick forests of Indiana, and making several detours to salt licks.

I've talked to people on the ground about the strike here tomorrow, and the single thing everyone brings up is just how shockingly wide the support for the strike is. Businesses that no one would have expected to support it are doing so.

Again, we don't have an Opposition Party, not even close; these people are a dangerous fucking joke, the lowest bar possible. We have a room full of people who are "colleagues" with fascists, who protect their capital at all cost & do the bare minimum to gaslight enough people to get reelected.

Universities keep thinking "If we just give Trump what he wants, he won't attack us" despite the entire 20th century (and most of human history) proving otherwise. Do none of these institutions have history departments?

it's always tickled me that Montréal orients everything in the city by the St.-Lawrence river, using their own compass based on the flow of the river for naming things, which leads to situations where one of the most southeastern boroughs is named southwest...
