Previous studies have shown that insects are dwindling for several reasons, including climate change and habitat loss, and other studies have shown shrinking number of pollinators, and yet more have shown coffee and cocoa plants themselves are hurt by the interaction. But the sum of all that is even worse than just the parts, study authors said.
"There will be this double hit of climate change impacting coffee itself, the coffee plants, but also impacting the pollinators on which it depends so that's quite worrying for those of us who like coffee," Newbold said.
That doesn't mean no coffee or chocolate, just more expensive indulgences, said study lead author Joe Millard, a computational ecologist at the Natural History Museum in London.
