Coral reefs are also very important to people. The value of coral reefs has been estimated at 30 billion U.S. dollars and perhaps as much as 172 billion U.S. dollars each year, providing food, protection of shorelines, jobs based on tourism, and even medicines.
Bumblebee is one of the smallest and physically weakest Autobots. While his stature allows him to do his job better than most Autobots could manage, he is self-conscious about his size. Maybe this is why he makes fast friends among the humans.
While most bumblebees are wild, some species are increasingly used commercially to buzz pollinate. Research shows that under the same conditions, bumbles can actually pollinate more flowers per bee than honeybees, though a honeybee colony (50,000 bees in the summer) is much larger than a colony of bumblebees (only 250).
