If it's an environment that isn't conducive to honey bees then it's not magically going to become so. I'm not anywhere near farming area or anything other than suburban lawns and a handful of landscaping bushes. The bees have move on.
Me spraying vs not spraying isn't going to change my local ecosystem if it doesn't already exist.
The bee population is very small now, but only because people keep killing them faster than they can grow back in numbers. They didn't "move on" as if they would never return. They do return, spread out and form new colonies as much as they can.
You don't have to have farming area at all, to have bees. I've raised crops in suburban neighborhoods for decades but besides that, there are plenty of neighbors (and myself) with flowers, flowering bushes and tree, etc. and there are even people who have bee hives on their property in many cities trying to help build their numbers back up.
Would you rather it be wasps? Thanks to people killing off the bees, I now have mostly wasps pollinating my larger bloomed things, and I even leave old wood around for them to have to build nests (they chew off the material to take elsewhere, do not build nests IN the old wood), though there are bumblebees around when the hibiscus and okra bloom but they are too large to pollinate a lot of things.
