An often heard or read phrase related to agricultural production goes as follows: You can thank pollinators for one out of three bites of food you eat. Of course, that assumes you have a nutritionally balanced diet. But the point is clear. One third of crops used to produce food for human consumption come from plants that depend upon pollination to reproduce. In the United States it is estimated that the value annually of crops that are pollinated by insects is $40 billion and this figure does not include the value of non-food crops that also depend upon pollinators, like cotton, for example. The market size figure presented below is an estimated value to the world every year of pollination done by insects and animals.
For anyone not familiar with pollination, it is the process by which pollen is moved from one place on a flowering plant to another. Pollen grains contain the male contribution to the fertilization process and are moved through pollination to the female parts of the plant so that offspring may be produced. Without pollination, a flowering plant will not bear fruit or seeds. Insects and some animals serve as transporters in this process, as does the wind for some plants.
