As it happens, people worldwide mostly drink Arabica coffee, a coffee variety which originates in the Ethiopian highlands. The cultivated Arabica depends on its wild relative for the production of new and stronger varieties.
British researchers now say that extreme weather changes might pose a great threat to the survival of wild Arabica plants. If global warming continues, there will only be a small area left where wild Arabica can survive at the end of this century.
And though there are a number of other external factors that influence the survival of wild Arabica, this just might be another good reason to take care of the planet we live on.
