This past January, at the St. Innocent Russian Orthodox Cathedral in Anchorage, Alaska, friends and relatives gathered to bid their last farewell to Marie Smith Jones, a beloved matriarch of her community. At 89 years old, she was the last fluent speaker of the Eyak language. In May 2007 a cavalry of the Janjaweed — the notorious Sudanese militia responsible for the ongoing genocide of the indigenous people of Darfur — made its way across the border into neighboring Chad. They were hunting for 1.5 tons of confiscated ivory, worth nearly $1.5 million, locked in a storeroom in Zakouma National Park. Around the same time, a wave of mysterious frog disappearances that had been confounding herpetologists worldwide spread to the US Pacific Northwest. It was soon discovered that Batrachochytrium dendrobatidis, a deadly fungus native to southern Africa, had found its way via such routes as the overseas trade in frog’s legs to Central America, South America, Australia, and now the United States. One year later, food riots broke out across the island nation of Haiti, leaving at least five people dead; as food prices soared, similar violence erupted in Mexico, Bangladesh, Egypt, Cameroon, Ivory Coast, Senegal and Ethiopia.
