“Dependencies are aspects of environmental assets and ecosystem services that a person or an organisation relies on to function. A company’s business model, for example, may be dependent on the ecosystem services of water flow, water quality regulation and the regulation of hazards like fires and floods; provision of suitable habitat for pollinators, who in turn provide a service directly to economies; and carbon sequestration.”
