🏙️ Immediate to Short-Term (Days to Centuries)

• Hours to weeks: Power grids fail; nuclear reactors melt down without maintenance[11].
• Months to decades: Urban areas flood as drainage systems fail; buildings decay from weather and plant growth[6][11].
• 100–300 years: Steel structures collapse; concrete buildings crumble[5][7]. Most cities become overgrown forests[6].

Medium-Term (Thousands of Years)

• 1,000 years: Visible surface structures (e.g., roads, monuments) are buried or eroded. Plastics fragment but persist chemically[5][7].
• 10,000–250,000 years: Nuclear isotopes (e.g., plutonium-239) remain detectable in sediments and ice cores[7]. Mining tunnels fill with sediment but leave identifiable "industrial fossils"[7].
• 500,000 years: Microplastics and polymer layers in ocean sediments endure[5][10].

Long-Term (Millions of Years)

• 1–7 million years: Fossils of humans and domesticated animals persist. Geological strata show elevated carbon levels and mass extinction markers[4][8]. Deep mines and landfills remain as distinct layers[7][10].
• 50–100 million years: Continental drift subducts surface evidence; satellites decay or drift into space[3][10]. Only deep geological traces (e.g., mine shafts, isotope ratios) might endure[3][10].
• 250 million years: Next predicted mass extinction eradicates all mammals, including any remaining human traces[9].

Near-Permanent Traces

• Space artifacts: Lunar landers, Mars rovers, and Voyager probes persist for billions of years[3][10].
• Radio signals: Human broadcasts travel through space indefinitely at light speed[5].

Key Factors

• Detection likelihood: Aliens or future species could find traces for 100+ million years via deep geological analysis or space exploration[5][10].
• Total erasure: Requires Earth's destruction (e.g., solar expansion in 5 billion years)[10].

We do have an impact but the earth will 100% be ok when we are dead and gone eventually. A million years ain't shit to the earth.

We humans are a virus…a parasite and the earth will be better off once we are extinct.

"let"

The sociopath fascist capitalists won. They have multilayered protection from us from propaganda dividing us and turning us on one another without end to government capture and having the exclusive use of state violence to protect the capital markets and literally having state sanctioned murder for for private profit. This isnt a war, this is a well oiled Orwellian occupation. The people surrendered half a century ago without terms and received the delusion that they'll be the rich ones one day herp derp.

We can't do anything about the misery they spread, and that sucks. We don't have to add to our misery by pretending there's hope and we can turn any of it around. They're going to do what we're going to do and short of being a lone "terrorist" that takes a pot shot at them like Luigi there's nothing to be done, because half of us are too cowardly and social opiate addicted(fast food, social media, literal opiates, etc) or too deluded and actually on the robber baron's side out of pick me mentality to take it as a rallying cry.

Only the planet itself, our shared habitat, can stop them. And it will, regardless of all the studies they kill, ecological treaties they betray, and all the propaganda they spread. The capitalists reign of terror will end when enough of their suckers are starving, not before.
