Dr. Aaron Davis, has one of the greatest titles of anyone I have ever interviewed in the last four years of doing this podcast. He is head of coffee research at the Royal Botanic Gardens, Kew. And in that role, he co-authored of two new scientific papers which demonstrate that many species of what is known as "wild coffee" are threatened with extinction, and that is in large part due to climate change. As Dr. Davis explains, we coffee drinkers do not generally consume wild coffee. Rather, there are two species of coffee that are not "wild" that most of us drink, called Arabica and Robusta. But you will learn, the fate of the two species of coffee we drink and that of the 124 species of wild coffee are closely linked. Aaron Davis also holds the title of Senior Research Leader at the Royal Botanic Gardens, Kew. And we kick off talking more generally about the science of coffee before having a longer conversation about the broader broader social and economic implications of his research into climate change and coffee excitation.
