From a broad perspective, everything in nature is perfectly efficient according to its own laws and systems, even if things seem inefficient from a human perspective. When humans apply intention, understanding, and judgment, things appear out of balance. However, systems like riding a bike or driving a car follow the laws of physics perfectly, even if there is wasted energy from a human perspective. Ultimately, nature and its systems are perfectly aligned, though humans may perceive imperfections when wants or understanding are limited.
