The birds and the bees pollinate about a third of our food, and without them we can say goodbye to nectarines, blueberries, and watermelons. Preliminary results from the Bee Informed Partnership survey of 6,128 beekeepers in the United States show that in the last year, respondents reported losing 42.1 percent of their total colonies. "We wouldn't necessarily starve if we were to lose bees but our nutrition would be greatly reduced in quality and variety," says Elina L. Niño, at the Department of Entomology and Nematology at UC Davis. Fortunately, there's something all of us who have a little land can do — start a beehive. Here's how.
