The Endangered Bee

Listening to a podcast while mowing the lawn, I heard a TED talk given by Marla Spivak on the disappearance of bees. As I was almost mowing over a few thousand clover that had cropped up on our front lawn Marla began saying that due to the clearing of land for monocultures, such as corn and soy, and the pesticides needed to maintain them - the bees are dying. Bees love wild flowers such as clover and alfalfa. As I looked down at my feet I started to see bees, a couple at first, then more: maybe a dozen of them buzzing from clover to clover. 
Marla has allowed her garden to become overgrown with wildflowers. I'm not sure if our neighbours would appreciate it, but it would be nice to have our garden as a haven for the endangered bee.
