Wing B · the bad
The same qualities that made the potato indispensable — cheap, clonal, uniform — made whole societies fragile. This wing does not soften that.
Chuño provisioned the forced-labour draft that fed Potosí's silver mines, where hundreds of thousands of Andean workers died. The potato's portability served conquest as readily as it served the Inca.

Europe built its dependence on a handful of clones descended from a few shiploads of tubers. Clonal propagation means no genetic reshuffling — every plant in a field can be killed by the same pathogen.

Ireland's poor lived on the Lumper potato. When blight struck, about one million died of starvation and disease and a million emigrated, while grain, cattle and butter continued to be exported under British land policy. Ireland's population is still below its 1841 level.

Blight in Scotland compounded the Highland Clearances: destitute crofters were shipped to Canada and Australia under assisted-emigration schemes that were often coercive in practice.

With supply lines cut, the western Netherlands survived on rationed potatoes, sugar beet and tulip bulbs. Around 20,000 died; children born to starved mothers show measurable health effects decades later.

Late blight and the Colorado potato beetle keep evolving resistance; potato crops are among the most heavily sprayed in the world, with new aggressive blight lineages such as EU_13_A2 forcing more frequent fungicide use.

Andean communities have fought to keep control of the landraces their ancestors bred, while commercial processing concentrates global production into a few uniform, fry-friendly cultivars.

Potatoes exposed to light produce solanine, a toxic glycoalkaloid. Poisonings still occur — most notoriously a 1979 outbreak that hospitalised 78 London schoolboys.
