China will become the biggest producer of milk in the world, and much of this will be produced by yeast. The American dairy industry will ban this technology, and vat-grown milk from China. China will retaliate by blocking American milk exports. This will spiral into a trade war. However, despite grumbles from European fromagiers, the EU will ultimately allow the technology and imports from China cause they don’t have any fertilizer for their own cow feed or electricity for their bioreactors. Thus begins the EU’s too-late drift from American hegemony.
