"When you realize the value of all life, you dwell less on what is past and concentrate more on the preservation of the future." ~Dian Fossey
These little guys play a critical part in our entire ecosystems to function. Bees allow plants to reproduce through pollination. These plants contribute to the food system by feeding animals, aside from humans, such as birds and insects.
As you can see, this guy is carrying pollen from plant to plant and flower to flower in a process called pollination. 85% of our food crops and cattle is from the bees who pollinate. Without these bees, humans and animals could not survive, this is how important of a role they play in the food chain they we tend to overlook.
