Topic in Gardening courses
Bees and our food
Many plants need pollinators for their reproduction and to produce good fruits.
"Bees play an important role in pollinating flowering plants, and are the major type of pollinator in ecosystems that contain flowering plants. Bees either focus on gathering nectar or on gathering pollen depending on demand, especially in social species. Bees gathering nectar may accomplish pollination, but bees that are deliberately gathering pollen are more efficient pollinators. It is estimated that one third of the human food supply depends on insect pollination, most of which is accomplished by bees, especially the domesticated European honey bee."[1]
Worldwide since the end of the 20th century the number of pollinators is decreasing.
