Why are honeybees disappearing?
Bees are disappearing. They face many threats, from habitat loss to the use of toxic pesticides. An increase in urban developments means that many of the areas bees once called home no longer exist. Wildflower meadows and other areas with abundant plants are in decline, meaning bees are losing an important food source.

Are honey bees really dying out?
For years, honeybees were dying, and no one knew why. There have been some glimmers of hope recently. The number of bee deaths wasn’t as dramatic last winter. Studies began pointing the finger at pesticides. But a simple fact remains: Bees still are on the decline, and no one’s sure why.
To be frank, bees are disappearing because of humans. According to Woodland Trust, the biggest causes of bee population decline include everything from habitat loss to climate change. We destroy natural habitats, forests, wildflower meadows, and many other areas that once held flower species necessary for bee survival.
