Honeybees play an interesting and important role in nature.
In addition to making honey, honeybees help many plants reproduce.
They do this by pollinating the plant, which means to transfer pollen.
Pollination occurs when pollen is moved within a plant's flower or carried to another flower.
This is how the plants reproduce.
For reproduction to succeed, the pollen must be transferred from the male part of a flower to the female part.
Many plants depend on pollination for reproduction.
These include many fruits and vegetables.
Besides honeybees, there are many other pollinators, including birds, insects and other kinds of bees.
Without enough pollinators, many of our favorite fruits and vegetables would become more expensive and hard to find.
These include almonds and cherries.
Honeybees are important pollinators and play an important role in agriculture.
Beekeepers are people who keep honeybees.
In addition to collecting honey, some beekeepers provide pollination services to farmers.
They do this by raising and managing colonies of bees.
Farmers need the colonies to pollinate their crops.
Beekeepers can provide and manage bee colonies for farmers.
Honey bees are social insects that live in colonies.
A bee colony consists of a queen bee, male drones and thousands of female worker bees.
Each colony also contains eggs and immature bees in various stages of development.
The number of bees within a colony depends on seasonal changes.
A colony's population increases during the warm seasons and decreases during colder seasons.
In recent years, many bee colonies have collapsed, or disappeared.
A bee colony collapse occurs when a majority of the bees in a colony disappear and leave behind the queen.
Some beekeepers have reported losing 30 to 90 percent of their colonies.
This loss of bee colonies can cause significant problems for farmers who depend on them to pollinate their crops.
In some parts of the world a shortage of bees has increased the cost of renting bees by up to 20%.
There are several possible causes for bee colony collapse.
One possible cause is the use of new pesticides.
Other possible causes include infections from viruses, genetic factors, and malnutrition.
Changing weather patterns may also play a role as summers get hotter and winters get colder.
These changes in weather may weaken the bees, making it more difficult for them to fight infections.
Whatever the cause of colony collapses, it's important to understand that many parts of our world are interdependent.
Changes that affect one species may have serious effects on other species.
A change to our environment can start a chain of events that is difficult to predict.
In any complex system such as the Earth's environment, small changes can have unforeseen consequences.
The danger of unforeseen consequences is something we all need to understand better.
(The Earth's environment is an extremely complex system.)
