It was the first bee-decline study to be conducted in a natural environment. "People had found pretty trivial effects in lab and greenhouse experiments, but we have shown they can translate into really big effects in the field," said Professor David Goulson, one of the lead researchers. Bee pollination is worth as much as $15 billion to the agricultural industry. The number of bees in the U.S. has dropped by around 50 percent in the past 25 years.
