Read this excerpt from a passage.
Biomimicry is not cosmetic imitation. Buildings that simply look like a fish, a shell—or some other object in nature—are not using the principles of biomimicry. If a structure truly employs the principles of biomimicry, the natural features are incorporated because their designs work with the natural environment and are efficient. If one looks around to see what solutions nature has to offer, one may just be inspired to design a new, eco-friendly structure.
