I’m working on my next essay pulling together the horrendous polices you don’t know about. Stay tuned for “Agshittification Watch.” Until then, here’s the word you need to capture just how shitty things are, fuel for the food revolution we need. foodtruth.substack.com/p/agshittifi...?
The word agshittification appears on a dictionary card coining the new word by P.K. Newby.

My contribution to this year’s Climate Week is highlighting Big Ag and Big Meat, the foundation of so much that is wrong with today’s agrifood system. Read more on “agshittification,” because we need new language to create a healthy, sustainable food future. foodtruth.substack.com/p/agshittifi...

When the enshittification of the agrifood system is so epic it needs its own word to reflect its vile practices and true costs to public health, the planet, and society. Thanks to @hope.net for the stage to debut this phrase live after 2 years in the making, and to @pluralistic.net.web.brid.gy!
