"Recently, my laboratory at Simon Fraser University conducted a study on farms that produce canola oil that illustrated the profound value of wild bees. We discovered that crop yields, and thus profits, are maximized if considerable acreages of cropland are left uncultivated to support wild pollinators."
I don't buy into this at all. Land is very expensive, to leave some land to grow "wild" to support native pollinators costs money. If this even where the case, that farmer would be buying pollination services from beekeepers to provide that pollination need instead of leaving the land un farmed, many of the crops grown over our vast country side don't require insect pollination. Perhaps he is talking vegetable farmers? in which case they would buy in pollination.
