Bumble Bee buzzing among flowers looking for nectar

I chased a huge bumble bee buzzing around the flowers in my garden as it gathered nectar, trying not to get stung. There was one scary moment. Bumblebees flying around in your garden pollinate flowers as they gather nectar and pollen. Humanity needs bumble bees for so many reasons. Many people see bumble bees in their gardens sipping on the flower's sweet nectar for energy and collecting the pollen full of protein to take back to their nest. Without bumblebees pollination would not happen to many plants and this would affect the food cycle.
