Plants are vital to humans and many living things.
Through pollination and resulting fertilization, plants produce necessities,
such as food for nourishment, cotton for clothing, lumber for shelter, and
seeds for reproduction.
Pollination is the transfer of pollen in a flower
from the anther (male) to the stigma (female). It may be intentional,
incidental, or accidental. Methods of pollination: cross pollination (used by
most plants)—the transfer of pollen from one flower to the stigma of another in
a different plant of the same species by an insect, animal, wind, or water; self
pollination—the transfer of pollen to the stigma within the same flower through
shedding; artificial pollination—hand pollination by a human.

Performance varies in pollinators. Butterflies do
not always efficiently pick up pollen with their bodies, legs, or tongues,
although they are helpful with pollinating certain plants. However,
hummingbirds, with their long tubular bills, skillfully retrieve pollen from
deep-throated flowers. Actually, the exceptional pollinators are bees. They
intentionally collect nectar for energy and pollen for protein, and nature helps
them gather this pollen with fuzzy bodies, special hind legs and abdomens, and
electrostatic charge. Furthermore, some bees, especially bumblebees, buzz
pollinate—move flight muscles rapidly, causing vibration in the anthers to
better release pollen in self-pollinating plants like tomatoes. Because a large
portion of food consumed is dependent on bees, they are worth billions to the
global economy. Supposedly, Albert Einstein estimated that humans would only
exist four years if bees disappeared; therefore, the noticeable population
decrease in these insects is alarming. Habitat loss and degradation threaten
wild species. Consequently, growers rent or purchase bees (commercial crops are
primarily pollinated by honey bees), but managed bees suffer from parasites,
pathogens, and pesticides. In some regions of China, where pesticides have
discouraged bumblebees in apple and pear crops, artificial pollination is
necessary.

Most
essential is the pollination of trees. Besides providing food and shelter,
trees are the lungs of the earth—they release oxygen. They also furnish
fuel—sunken, compressed trees ultimately become coal which fuels electricity.
How about pines (conifers) which produce turpentine through the distillation of
their resin?
Obviously, pollination is crucial. The sudden urge
to swat annoying bees or destroy any pollinators should be repressed—these
beings may determine whether there are delicious apples to savor or colorful
flowers to smell. And these flowers will in turn attract needed
pollinators!
