The Shape of Change
Chapter 3 introduce the first central principle of Environmental Biodynamics—that complex systems cannot interact directly, nor exist in isolation. It also introduces the corollary principle that although the interface is composed of constant change (i.e., processes) it retains a quantifiable topography—the shape of change—driven by stochastic, deterministic, or chaotic processes. The implication of this, from the perspective of environmental medicine, is that the environment and human physiology are integrated via an interface. An interface emerges wherever the measurement of one system’s state intrinsically includes inputs from another system. And thus, to understand how the environment influences us, and vice versa, environmental medicine must adopt a functional perspective that focuses on the organization of system dynamics and complexity. This is achieved by characterizing the deterministic, stochastic, and chaotic processes that shape environmental homeostasis.
