The fact that bees pollinate one-third of our crops make them pretty important to our world. The fact that we have bombarded our crops and lands with all kinds of pesticides thanks to DOW and Monsanto doesn't seem to bother our world as scientists are now trying to figure how to build RoboBees. Yes mechanical robots to do the work that bess currently do.
Years ago in the coal mines they used to bring down canaries - when these tiny birds would become sick or die the workers knew the air is bad. They didn't bring down a mechanical bird and pretend all was okay.
GMO foods, pesticides, toxins - we can say all day long they are not the culprit. I remember someone saying the air at ground zero was safe as well.
So go ahead Mr. Scientist, work on your RoboBees and maybe someday we'll have RoboFood, RoboPlants, and RoboChildren too.
