AI may already grasp what most humans refuse to see: we’re in ecological collapse. Reefs bleaching, insects gone silent, oceans emptying out. The Sixth Mass Extinction isn’t coming — it’s almost over. 1/ Image But AI isn’t free. It runs inside the very fossil-powered, supply-chain civilization that’s destroying the biosphere. If that system crashes, the machines lose power, cooling, and hardware — and die with it. 2/ Image

Environmental laws were created to weigh or prevent damage before action. Now, across industries, they’re bypassed or gutted. From fracking to forests, here’s a thread of the unraveling of protection.🧵 The Big Open…..disappearing quickly. 2. Fracking (The Halliburton Loophole)

Until recently, whitebark pine was a vital food resource for grizzly bears in the the Greater Yellowstone Ecosystem (GYE). It provided essential nutrients as they prepared for winter hibernation. The large seeds, or nuts, of whitebark pine 1/10 Image are a high-energy food rich in fats, carbohydrates, and protein. This made them a sought-after resource for grizzly bears fattening up in the fall before denning. By 2010, mortality levels of whitebark pine in the GYE had reached 73%, 2/10 Image

Studies showed that Agent Orange could only affect plants as it worked specifically on a plant pathway that animals didn’t have. For years, veterans were accused of scamming the system.

Roundup is no different. 1/6
Image Roundup affects bacteria that have the same metabolic pathways as plants, including our symbiotic gut. Roundup doesn’t directly kill insects. It kills them indirectly over longer time periods by destroying symbiotic bacterial relationships—compromising their immunity. 2/6
