I have just read 'Empty Harvest: Understanding the Link Between Our Food, Our Immunity and Our Planet' by Bernard Jensen and Mark Anderson and there was one fragment about coffee that simply terrified me. The authors say that the progenitor of all coffee bean trees is from Ethiopia and if the last of these trees died from neglect, the hybrid species would become the ultimate source of coffee beans. But if the coffee bean trees around the world were then killed by a species-specific disease, there would be no original seed to fall back upon. Then, coffee bean trees - not to mention coffee breaks - would become extinct. Finally, the authors say that "coffee is not a matter of life and death" though I don't agree.
What do you think of this scenario?
