ANDHow on earth did wild bees manage to survive millions of years without that witches brew?
The words 'stewardship of the land' seem to pop into my mind.They chose to colonise areas of natural forage. If forage became unavailable, e.g due to climatic conditions, the bees didn't survive in that particular environment.
Today's managed colonies have no choice where the beekeeper puts them. If they are put in a nutritional desert, they are either artificially fed or they die out.
