When spring comes, the bees move active. Bees pollinate flowers which makes
flowes to grow in wide field. Therefore, the season "spring" is related to bees a lot.
However, these important bees are being sick because of sac brood that occurred
in 2010. In this period, 90% of bees died. Moreover, when winter came and weather
became colder, bees died once again after the sac brood. If bees keep dying
like today, then what problem will occur?

Anytime bees disappear, fruit orchard harm damaged. As mentioned, bees are
important pollinators not only to flowers but also to farmers. If bees don't pollinate
because of several reasons, then in the year, fruit can't grow. Bees can't fertilize
flowers so we can't eat fruit too. This problem makes people concerned.

People have to make practical way to resolve the proplem. Such as making
artificial bees that have antibody in body, or using DNA to make baby bees, etc.
