Maryland beekeepers have lost an average of 60% of their honeybees in the past year, according to a survey from the US Department of Agriculture. That’s one of the highest death rates in the country. Honeybees have been mysteriously dying in large numbers for years now and scientists still don’t understand exactly what’s causing the problem. One of the people trying to understand what’s going on is Wayne Esaias, former president of the Maryland State Beekeeper’s Association and a Master Beekeeper. He joins Nathan Sterner by phone to talk about it.
