In recent years, there has been an increase of bee colonies that have suddenly and mysteriously died. This is called bee colony collapse. The worker bees leave the hive and the queen, babies, and food remain. Without the worker bees, the hive cannot survive. Bee colony collapse negatively impacts the environment around the hives. The bees pollinate the plants and crops that surround the hive. Without bees, the plants and crops would not bloom or produce fruits and vegetables. Scientists think there are a few reasons why the bee colonies are collapsing. The first is the increased invasion of a mite in a hive. The use of pesticides by farmers and gardeners may also be killing the bees. The pesticides are used to keep bugs that destroy plants and crops under control, but they are unintentionally killing bees as well.  How does the author support the idea that bee colony collapse negatively impacts the environment?*The author explains that pesticides help to control harmful bug populations on plants and crops.The author explains that without bees, crops and plants won't be pollinated.The author explains that without worker bees, a hive can not survive with just a queen and babies.The author explains that the invasion of mites may be one reason that bee colonies are collapsing.
