Bizarre.
Actually, there would just be no pollenating plants. Still, I can’t imagine life without bees. Except for all the ones that stung me. Killer bees I can do without, and of course Murder Hornets. And all hornets in general. Honey bees I don’t really see as a problem, though. Except for the rare times when even they will sting you. But the good part about it is that they die as a result.
Bees are not native to north or south America. They were brought here by the Europeans. There are plenty of insects that pollinate plants such as wasps, moths, butterflies, flies, beetles...... Wasps pollinate and destroy aphids.
I’m sure that the bees brought to the protest were really happy to have been uprooted from their familiar homesites to go on a big city adventure.
I was talking to a bee keeper in southern Ohio who told me that the bee kill off was over several years ago. It isn’t a problem here anymore. That was in a county that was more hay field than crops that used round up.
