Bee off

摘要

Honeybees are sensitive creatures. From time to time a hive simply gives up the ghost and vanishes. Colony collapse disorder, as this phenomenon is known, has been getting worse since 2006. Some beekeepers worry that it may make their trade impossible, and could even have an effect on agriculture-since many crops rely on bees to pollinate them. Climate change, habitat destruction, pesticides and disease have all been suggested as possible causes.
