Bees, as you may have heard, are in trouble. Many hypotheses have been forwarded as to why honeybees populations have been dropping, including pesticide use (the most obvious), bee mites, lack of forage, and even cell phones. All these hypotheses have some evidence to back them up, and the problem may be a combination of them all.
Some people plant bee gardens, just as one might plant flowers for hummingbirds or butterflies. This helps by providing nectar and pollen for foraging bees, and can support all kinds of good worker bees besides honeybees.
If you're wondering, "Is there one more thing I can do for bees? Just one small thing?" Hagen-Daas has an answer for you. Check out their Help the Honeybees website, an interactive site done in Flash. They have more information on bees, tips for helping bees, info on what the company is doing for bees, and a cute little bee-maker so you can email animated bees to your friends.
