Forget that complex coffee order you’ve been perfecting: in the coming decades, the coffee industry might be going out of business. Starbucks sustainability director Jim Hanna worries about the repercussions of varying rainy seasons, hurricanes, and crop depletion for the drink many people can’t live without. “What we are really seeing as a company as we look 10, 20, 30 years down the road—if conditions continue as they are—is a potentially significant risk to our supply chain, which is the Arabica coffee bean,” he told The Guardian. Hanna is part of a business coalition pushing for reforms to halt climate change, and hopefully, they’ll be heard. A coffee-less world would mean a lot more grumpy people.
