The only thing that may save some bees is the general laziness and apathy that most people have about the outdoors now. It won't happen in the vast, vast stretches of HOA monitored hell that has sprawled across most of the USA, but at least in other neighborhoods I expect the people letting their yards overgrow will help a bit.

Still, everything gets washed in pesticides all the time. I don't have high hopes for our ecosystem anymore.
