Bees are Master Pollinators and Cannot be Mimicked Cost Effectively
The study of biomimicry and sustainable design promises great benefits in design application. It affords means by which to promote cost-effective, resourceful, non-polluting avenues for new enterprise. These “blueprints” have existed previously as underappreciated strategies by relatively unfamiliar organisms. An important final caveat, however, must still be addressed. One cannot leave the student with the misunderstanding that once copied, species are expendable. Biomimicry is intended to
