Monocultures in Agribusiness. One 'public secret' many outside of the industry might not be aware of is the prevalence of monocultures in crop farming. Vast expanses of land planted with the exact same genetic line of a crop. While this makes farming operations easier and often more profitable in the short term, it's a ticking time bomb for pests and diseases. One well-adapted pathogen could wipe out an entire crop species in an area (look up citrus greening in Florida), because there's no genetic diversity to halt its spread. But hey, it keeps the costs down...until there's no food to eat.
