During Napoleon's time, much of the coffee-producing area was lost by the Dutch to the English. In 1825, the British began development of their property in Ceylon (now Sri Lanka), and every suitable piece of land was planted to coffee plantations. By 1870, Ceylon was the world's greatest producer of coffee. Java remains a slang term for coffee, reflecting the time when coffee production centered in that part of the world. Today, however, 90% of the world's coffee comes from the tropical Western Hemisphere. Sri Lanka is now known best for its tea production, and the cup of tea, rather than coffee, has become a familiar part of England's culture. As with the Irish potato famine, a fungus was responsible for these changes, but only because of the agricultural practices of human beings.
