Wait until you hear about deadly toxin producing bacteria.

You only need about 6 kg of Clostridium botulinum to produce enough toxins to kill all mammals on earth.

Assumptions:

  • weight of a single bacterium is 1 picogram
  • a single bacterium produces 0.5 picograms of toxin
  • All mammals on earth are 1.4 gigatons of mass
  • a lethal dose is 150 nanograms per kg

You can make it at home!

Yes but the delivery is a problem. How do we package, ship and then get each mammal on earth to ingest 150 ng of the toxin?

Well, if all it takes is 6 kg, I don't think it would be that hard to make like a few tons and fly around the world throwing a kg at a time into any body of water you find.

Sure, you wouldn't kill everyone, but probably most 🤷‍♂️

I think about 96% of mammal biomass is either humans or domestic animals so if we ignore the 4% wild animals it suddenly because a much easier task.

Like, throwing enough botulinum toxin into the ocean to kill all the whales would be annoying.

Are you a Batman villain, threatening to poison Gotham's water supply.

It would a lot less interesting.

Literally everyone dies except a few that drink only bottled water. Society is now 90% people who believe that alkaline water is magic

More likely 10-15% of people die then everyone figures out it's the water, identified the cause of death, develops filters to remove the toxin, and then the filter becomes commercialized.

Like the first half of the movie is just what you would expect from a batman movie, but then after thousands die and batman catches the villan it just conintues into a documentary about how this event eventully led to the "2026 Water protection law" and the political fights around it.

Genocide is evolutionary beneficial for the toxin producer, maybe there's a ring of truth to it. Poison everything around you, free up resources for yourself.

I always wondered if the toxin didn't kill the bacteria.

Bacteria doesn't have nerve cells.
