A recent study led by the University of Oxford suggests rising temperatures and a lack of insects to pollinate cocoa flowers could threaten chocolate supply. The research took place in Brazil, Ghana, and Indonesia — countries that together account for a significant share of cocoa production worldwide.  In each location, the team set up study plots and applied six different pollination treatments: 0%, 20%, 40%, 60%, 80%, and 100% hand-pollination…
