Yeah, just because we can reduce our use of pesticides doesn't suddenly make all of the bee colonies we killed with it come back to life. I get that.

But nature is resilient and if we stop dousing everything in nerve toxins then maybe we'll see the ecological web of insect life doing its thing again. That improves the soil and plant life, gives food to small critters, and both of those indirectly helps the bees. So it kind of does undo the damage in a roundabout way.
