Recently I learned that plants like Bambara Nuts (africa) and Water Lentils (duckweed) have complete amino complexes and b12. They're probably not the only ones either.

There's also many pest/drought resistant perennial crops that are nitrogen/nutrient fixers that eliminate the need for fertilizers and pesticides.

I expect that the impending climate induced supply chain collapse of global agriculture will force people to return to these more ancestral, and arguably superior, food sources.

Huh, isn't duckweed pretty easy to grow?

Just watched a lady "grow" it in buckets of pond/tap water. It doubles in biomass every 48h. Literally just let it sit there.

Most things with weed in the name is going to be easy to grow. A lot of people with aquariums or ponds feel plagued by it. I love it for aquariums it's one of the few things that can out compete algae

Youtube has sent me down the rabbit hole. Almost every common weed that's not native to North America was once a staple food crop in Europe.

But in the mid 20th century big agriculture realized they'd make more money selling annuals, fertilizer, and pesticides... instead of letting people grow perennial plants that solved those problems on their own.

most of them escape in the wild, and established wild population. iceplant is another one, its from south africa, it actually doesnt help with preventing spread of fires,it blankets the coasts of california. relatives of the plants are quite nifty succulents for hobbyist(aizocae, aka stone plants) while the ornamentals are very hard to take care off, the iceplants is very hardy and invasive. blue gum, a type of eucalyptus grows fast, also invasive but the biggest problem is since its a eucalyptus it makes fires more dangerous because of the oils.

yes, but also super invasive. we have them in areas where thier are bonds in norcal they blanket the entire water surface. they spread by vegatative propagation.

Over >50% of the space humans occupy is for agriculture

i think it's more like >90%.

i.e. of the area that is used (Agriculture, Urban and Built-up Land),

urban and built-up land is 1m km²,
agriculture is 48m km²,

so agriculture is 48 of 49 millions km² used, that's 98%. The remaining 2% are for streets and housing.
