The synergistic effect of pesticidesin hives

摘要

How bad things in the environmentgang up and kill bees. In many ways, honeybees are the canaries in the coal mine, the critters that die first when the air gets bad.For the last several years, people have been in a frenzy over the high mortality of honeybee hives. Not only are they concerned about bees, but they're concerned that pollination of food crops will be threatened. But it's not one thing in the environment—like methane in the coal mine—thatthreatens honeybees. It's a combination of things that don't just add together, but multiply. One plus one doesn't always equal two; it may equal 2,000. That's called synergism.
