Our human health and wellness rely upon the quality, availability and distribution of key substances, such as air and water. These substances are generated through the continued vitality and service of cycles and processes of earth’s systems, in this case, the atmosphere and hydrosphere. How and where we live affects these systems, cycles and processes, and in turn, the substances which sustain us. Our choices and decisions such as: how often, when and where we drive versus walk to a destination; whether to reside within the city or suburbs; or where to shop – all have an evidenced and vast cumulative effect on natural systems.
