“Horses come with speed, social status, and occasionally courage. Still, their strides are too long and inconsistent to carry strenuous weight in extreme conditions. For that, empires needed mules.”

I had no clue Darwin wrote a whole book on earthworms. Rachel Carson with them gems.

Women farmers in Xochimilco and San Gregorio are restoring chinampas (high-yield island farms) using canal-mud fertiliser, biofilters and invasive-fish barriers. The program has certified 16 producers and buffers floods, cools the city and shelters the axolotl. buff.ly/0gIJjxl

Women in Mexico step up to protect ancient Aztec farms and save a vanishing ecosystem
In Mexico, traditionally women did not inherit chinampas, island farms first built by the Aztecs thousands of years ago.

“People of African descent played critical roles in Guerrero and the rest of New Spain as plantation laborers, mine workers, coastal militiamen, and arrieros. As a common pathway for formerly enslaved afrodescendientes, arrieros were also connected to emancipation and social mobility.”
“Globally and historically, most mules respond to calls from arrieros. As of 2021, over half of the world’s mules lived in Spanish America, with a third calling Mexico home. How this happened has everything to do with the Spanish empire, slavery, and racial capitalism.”
“…whereas sheep proved accidental weapons of conquest, mules were calculated tools. Unlike most livestock, mules cannot reproduce. Instead, mule breeding increased alongside Iberian expansion of colonial mines & plantations & the racialized laborers who drove mules for empire.”

'Another unoccupied house collapsed into the ocean along North Carolina's Outer Banks on Saturday night. It's the 11th house to collapse since mid-September.

In total, 22 homes have collapsed into the ocean in the area since 2020.'

I want more people to care that SNAP benefits are being cut off on November 1. 40% of SNAP beneficiaries are children. This is callous and vile.

It's finally here! 100+ scholars, global scope, practical insights. “Climate Obstruction: A Global Assessment” shows how organized interests stall policy—and how governance can respond.

“what happens if we also reconnect with the mule? What can mules teach us about the black history of land and violence in the United States?”

A terrific piece of #envhist on mules, labor, and how “empire doesn’t always win” from @roguechieftan.bsky.social

"[they] live in this plumbous atmosphere, breathe it, swallow it...without danger, if one believes American documents."
From French scientist Armand Gautier on US farmworkers using lead arsenate in the 1910s. France banned agricultural arsenic in 1916. We still use it today.
