1. When Columbus crossed the Atlantic, he didn’t just bring ideas. He also started the exchange of food, animals, insects and disease around the world: "All of the great diseases from smallpox to measles to influenza …  [did not] exist in the Americas because they didn’t have any  domesticated animals. When the Europeans came over, it was  as if all the deaths over the millennium caused by these diseases were  compressed into 150 years in the Americas. The result was to wipe out  between two-thirds and 90 percent of the people in the Americas. It was  the worst demographic disaster in history.”
