At one time, people ate only food that was local and in season, but not anymore. Food diversity has declined. Food is now homogenized. Professor Rob Dunn examines how dependence on single species of crops threatens human survival. He writes of the Irish potato famine, “chocolate terrorism,” a desperate race to save seeds for future generations, and more. Scientists have discovered more than 300,000 plant species, but “80% of the calories” people eat come from just a dozen species. Dunn warns that pathogens, pests, wars and famine can obliterate a society’s food supply. He explains that it’s urgent for qualified scientists and farmers to study and breed different varieties of crops. getAbstract recommends his report to consumers, food industry professionals, farmers, scientists and investors.
In this summary, you will learn
- What factors spur declines in food diversity,
- How mono-crops have contributed to local food disasters in the past,
- Why humans must save seed, and
- Which pathogens and pests threaten specific crops.
