Honeybees specifically pollinate roughly 90% of all food we eat. That is about one in every three teaspoons of food we put into our mouth. Whether you are a vegan, vegetarian, or meat eater - everyone is affected by the work of a honeybee.
Bees pollinate the flowers of fruits, vegetables, nut trees, and regular flower bushes. They collect the pollen by rubbing themselves around inside a flower - then they leave said flower and rub around in the next. This method picks pollen up from one flower and transfers is to another. To collect large amounts of pollen they put it into the sacks that they have on each back leg (we call them pollen sacks)
Not only do they have large pollen sacks - they also have stiff hairs on their back legs that allow them to collect and spread pollen. When pollinating honeybees only travel to flowers within the same family - meaning that the pollen is not mixed among different types of plants.
Some of the fruits, vegetables, and other food products that honeybees pollinate include blueberries, broccoli, strawberries, pumpkins, tomatoes, peanuts, almonds, apples etc.
Without honey-bees, there will not be sustainable food.
