Cross-pollination from birds, bees and other insects is of value to more than just coffee. The United Nations Food and Agriculture Organization says two-thirds of the world's crops require it. But Mr. Ricketts and his colleagues point out that recent declines in wild and managed bee populations throughout the world have aroused concern, prompting the United Nations to create the International Pollinators Initiative. This is a program to coordinate scientific investigation on ways to conserve animal pollinators.
