Nicotine, THC, and cocaine are also insecticides. And psilocybin might be an insect repellent.
Thanks poison!
Basically humans will have sex with you, eat you, or make you a pet.
Sometimes more than one.
Tbf, this has proven to be extremely effective: Just think of how many tobacco or chili plants are grown today! Domestication really is a two-way-street
Funnily enough we try to cultivate everything we like, so in a roundabout way they were successful.
I think the book Sapiens makes the point that wheat has trained us into cultivating it for selfish needs.
(Except that it’s wheat, and that we annihilated 99% of its brethren to pick out the one that we liked so we could effectively clone it. But yes, we are the slaves…)
Caffeine is poisonous to us too, so I think it’s more accurate to say that humans enjoy the side effects of that particular neurotoxin. It’s generally not possible for someone healthy to drink enough coffee to die, but they sell pure caffeine (for research) and even seemingly small amounts of that will kill a person.
You can buy 200mg pure anhydrous caffeine pills at Walmart for like $5. It’s abundant and as safe as coffee if you don’t go nuts. The max daily recommended dose is 400mg, anything past that could cause harm
What I had in mind is more like this 25kg bucket. That’s enough to kill about 2,000 people, which is actually a lot fewer people than I would have guessed before I looked up the LD50.
I’ve never actually seen caffeine in a bucket myself, but I worked in a lab once that had a big plastic jar of it.
