The New York Times: A Battle to Save the World’s Favorite Treat: Chocolate— "Like many other crops, cacao is under constant threat from diseases and environmental challenges exacerbated by our tendency to grow only a few varieties with similar or identical genetic traits and defects."
The Guardian: Chips, Chocolate And Coffee – Our Food Crops Face Mass Extinction Too — "Take some consumer favourites: chips, chocolate and coffee.

Coffee yields in Tanzania have dropped 50% since 1960."
