Timeline for 1493
200,000,000 B.C.: Geological forces begin to break up the world’s single giant continent, Pangaea, forever separating the hemispheres. After this, Eurasia and the Americas develop completely different suites of plants and animals.
1493 A.D.: Columbus sails on second voyage, establishing the first consequential European settlement in the Americas. Without intending to, he ends the long separation of the hemispheres—and sets off the ecological convulsion known as the Columbian Exchange.
1518: In the first environmental calamity of the modern era, accidentally imported African scale insects in Hispaniola lead to an explosion of fire ants. Spaniards flee the ant-infested island in droves; colonists in Santo Domingo hold procession in honor of St. Saturninus, praying for his aid against the insect plague.
1545: Spaniards discover the world’s biggest silver strike in Bolivia. In the next century, the world’s supply of this precious metal will more than double, giving Europe an economic edge that will help it colonize Africa, Asia and the Americas.
1549: Initial appearance of tobacco—the addictive American drug that becomes the first global commodity craze—in China. That same year, Hernán Cortés inaugurates the human part of the Columbian Exchange by signing the first contract to import large numbers of Africans to the American mainland.
1571: Miguel López de Legazpi colonizes Manila and establishes continual trade with China—Columbus’s life-long, never-fulfilled dream. Knitting the entire inhabited planet into a single web of trade, Legazpi’s actions are the beginning of today’s economic globalization.
~1615: Earthworms come to northern North America in English ship ballast. During the next three centuries, they will re-engineer forests from Ohio Valley to Hudson Bay.
1630-60: The gush of American silver finally causes its price to collapse, setting off a the world’s first global economic calamity.
1644: Collapse of Ming dynasty. Long struggle between remaining Ming in south and incoming Qing dynasty in north leads the latter to forcibly evacuate most of the southern coast; millions of dispossessed people pour into the mountains, where they grow maize and sweet potatoes, American crops first smuggled into China from Manila and other European bases.
1775: France’s Flour War, set off by high bread prices, persuades King Louis XVI to allow the pioneering nutritional chemist Antoine-Augustin Parmentier to stage a series of publicity stunts to persuade farmers to grow potatoes, a distrusted foreign species from Peru. Parmentier’s PR is so successful that broad swathes of northern Europe are soon covered with a monoculture of potatoes.
1781: Britain’s “southern strategy” pushes Gen. Cornwallis’s army into North America’s malaria zone, an area dominated by malaria parasites introduced from Europe and Africa. Defeated by malaria, the British army surrenders to a general it never fought: George Washington. This ends the Revolutionary War.
1845: Europe’s potato monoculture, which is unlike anything ever seen in Peru, turns out to be especially vulnerable to another Peruvian import, the potato blight. Ravaging the continent from Russia to Ireland, the blight causes a famine that kills an estimated two million people, half of them in Ireland.
~1867: Léopold Trouvelot, French amateur entomologist, smuggles gypsy moths to Medford, Mass., hoping to breed them with native silk-producing moths to produce a more robust silk-producer. Their almost immediate escape sets off an invasion that continues today. Trouvelot hurriedly returns to France before the dimensions of the problem can be known.
1880-1912: Industrializing nations, desperate for the elastic belts, pliable gaskets and the aborbent tires needed by steam engines and vehicles, buy every scrap of rubber they can get from the Amazon’s rubber trees, the sole source of high-quality latex. The ensuing rubber boom collapses after an Englishman smuggles rubber trees out of Brazil. Soon much of southeast Asia is covered with this foreign tree.
1979: The golden apple snail is sent from Brazil to Taiwan to launch an escargot industry there. It escapes, proliferates, and becomes a major menace to the island’s rice crop.
