If one characteristic defines natural systems as opposed to industrial systems, it would be cycles. Factories epitomize Western thought as a linear platform where everything flows one direction, but biological systems flow in circles. Living systems don’t have landfills. As environmentalist Bill McKibben famously said, “In nature, there is no away.” God’s design doesn’t include waste or forever chemicals. Instead, living things eat, die, provide food for something else, and the material simply moves through loops.
