SUPPLY AND BEE-MAND

摘要

EVEN WITH SO many high-tech advances in agriculture, sometimes nature has the best solution. Bees are critical to cross-pollinating many U.S. crops, especially almonds, which cover more than 1 million acres in California alone. Each year these tiny insects help generate billions of dollars for the ag economy.However, the supply of commercial bees is frighteningly unsustainable. As acreages grow, beekeepers can't keep up. Factors such as poor nutrition and mites have caused colonies to die over winter. Beekeepers have been losing more than 30% of overwintered colonies for nearly 15 years.
