Study: World may run out of several potato, coffee, and cacao species by 2055

In Ghana and Ivory Coast, where the raw ingredient for 70 percent of world’s chocolate is grown, cacao trees will not be able to survive as temperatures rise by 2 degrees centigrade over the next 40 years, the study claimed. Bioversity International, a group of expert scientists, has said that the “sixth mass extinction” was already under way and a total of 940 animal and plant species were facing extinction worldwide. 

“Huge proportions of plant and animal species that form the foundation of our food supply are just as endangered [as wildlife] and are getting almost no attention,” Ann Tutwiler, director general of Bioversity International, wrote in an article for the British daily Guardian.

Potatoes and cacao might be the first food crops to be affected by global warming. Meanwhile, about 33 percent of the world’s farmland was estimated to be degraded, lacking the nutrients essential for growing crops. (Source:
