Here's Why All the Bees Are Dying

Bees are essential for life as we know it, but we're wiping them out.

Bees are having a really hard time right now. For about a decade, they've been dying off at an unprecedented rate—up to 30 percent per year, with a total loss of domesticated honeybee hives in the United States worth an estimated $2 billion.

At first, no one knew why. But as my colleague Tom Philpott has reported extensively, in the last few years scientists have accumulated a compelling pile of evidence pointing to a class of insecticides called neonicotinoids. These chemicals are widely used in commercial agriculture but can have lethal effects on bees. Other pesticides are also adding to the toll. So are invasive parasites and a general decline in the quality of bees' diets. br />
