Habitat selection, a basic principle of organic evolution, states that species prefer and gravitate to the environment in which their genes were assembled. Thus, we are completely dependent on our environment, including other species, and we must take steps to preserve the ecosystems that support us xi. Exemptionalists argue that technology can provide a substitute for nature. However, scientists and engineers have tried to build a closed, self-supporting system and failed miserably.
