The bee plays a critical role in our ecosystem, however, for the last decade or so, bee populations have been declining at an alarming rate. This is due to a number of reasons, such as pesticide use, climate change, pollution and more. Without bees, not only will we not have access to honey, a natural sweetener and antibiotic, but plants won't be pollinated, resulting in fewer flowers and possible food shortages. There are a number of small lifestyle changes that you can make to help support our ecosystem and its bee populations.
Bees are one of nature's good guys. They may possess a nasty sting they're willing to administer when agitated, but the good they do far outweighs the small chance of getting stung. Without bees, life on earth would be very different and a lot more difficult.
