There is an astonishing degree of complexity, order, and beauty in the natural world. Even so, and especially within the realm of living things, nothing is more complex than it needs to be to sustain its existence. Every aspect of the system serves a purpose. If it does not, the unneeded component eventually ceases to exist in future generations. Even with these constraints of resource and energy efficiency, we find boundless beauty and harmony in the natural world. Contrast nature’s “just the right amount of complexity” to the way many architects design buildings today. While nature is only as complex as it needs to be, architects and designers add excessive and inessential complexity to their buildings and landscapes when none is warranted.
