&quot;The causes of the pressure on these creatures intertwine: aggressive agricultural practices that grow crops on every available acre eliminate patches of wildflowers and cover crops that provide food for pollinators. Farming also exposes the creatures to pesticides, and bees are under attack from parasites and pathogens, as well.&quot;<p>Seems like this should self-regulate quite well. If there are no bees to pollinate the crop that needs pollination,  the &quot;aggressive agricultural practices&quot; would no longer be economical and the land would be naturally reclaimed.
