Pollination is the process of transferring the male part of the plant (pollen) to the female part of the plant (Pistil), which completes fertilization, thus enabling the plant to produce fruit or vegetables.   Up until about one hundred years ago, there were enough wild bees and other insects in the world to pollinate virtually all of the food crops being planted. Today, however, because of  intensive agricultural practices, and a sharp decline in the number of wild bees due to the use of chemicals, pollution, and destruction of insect habitat, there simply are not nearly enough wild insect pollinators to effectively pollinate our crops.
