If you've ever been stung by a bee, you may think that bees are nothing more than a nuisance. But the world's population of bees is dwindling, and no one knows exactly why. This population decrease will have an impact on food production around the globe. The winter of 2013 saw a loss of more than 30% of managed honeybee colonies. In the 1940s there were some 5 million managed beehives. Today, there is half that number.

While science hasn't confirmed the reason for the bee decline, otherwise known as colony collapse disorder, one theory is that bees are ingesting pesticides and fungicides while performing their very natural, and necessary, task of pollinating plants like blueberries, cranberries, cucumbers, pumpkins and watermelons. Bees collect pollen from these plants, or surrounding flowers, that have been contaminated with the chemicals. Some believe that the result is that entire hives are being wiped out.

Generally, science has thought that fungicides were not harmful to bees but some studies have shown otherwise. But it's not only fungicides. Bees locate their favorite plants by smell. Other pollutants, such as diesel fuel, are masking the smell of the flowers so that bees no longer recognize them.

There needs to be consideration of a large scale ban on pesticides and other chemicals that are killing off the bee population, or at least a serious look at the harmful effects. But, those concerned about the bees shouldn't rely just on government regulators. Homeowners can participate in providing safe, healthy environments for bees.

Still don't think you can or should try to make a difference? Consider a trip to the grocery store. Look around and remember that, of the food humans consume, one out of every three bites of food comes from plants that have been pollinated by bees, as well as other pollinators. More than 85 percent of plant species require pollinators to exist and grow.

If you want to help the bees, here are some things you can do:

• Purchase organic produce. That supports those who are helping the bees
• Use pest control measures that aren't toxic and avoid persistent pesticides
• Support your local beekeepers by purchasing the honey and other products they're likely to have for sale at your local farmer's market.
• Plant bee-friendly plants which are easy to grow. And it just takes a few scattered throughout your yard to create a good supply of pollen during the warmer months

When you are planting your summer garden it is simple to consider plants that are inviting and helpful to bees. Herbs and flowers attract bees to your yard and encourage them to pollinate. You don't have to have a large yard to do this. If you don't own a house or have a yard, a balcony or patio will work for a container garden or hanging plants.
