Soon, you might have to shell out more dough for your cuppa joe. Professor John Vandermeer was interviewed by CNBC and Southern California Public Radio about a coffee rust fungus that’s severely affecting coffee crops.

“The fungus is devastating crops in Central America, which has become one of the most important growing regions in the world,” according to Southern California Public Radio. “It's the worst outbreak in more than 40 years and it's estimated that this year's crop could be cut by a third or more.”

"The real question in my mind is whether this disease is going to be a continual problem like this not just this year, but in the foreseeable future," said Vandermeer. If it becomes a longer term problem, coffee lovers can expect to pay higher prices.
