The many components of natural capital can be viewed as providing essential goods and ecosystem services which underpin some of our key global issues, such as food and water supply, minimising climate change and meeting energy needs. Natural capital is the world’s stock of natural resources, which includes geology, soils, air, water and all living organisms.
Some natural capital assets provide people with free goods and services, often called ecosystem services. For example, a well-maintained forest or river may provide an indefinitely sustainable flow of new trees or fish, whereas over-use of those resources may lead to a permanent decline in timber availability or fish stocks. Natural capital also provides people with essential services, like water catchment, erosion control and crop pollination by insects, which in turn ensure the long-term viability of other natural resources. Since the continuous supply of services from the available natural capital assets is dependent upon a healthy, functioning environment, the structure and diversity of habitats and ecosystems are important components of natural capital.
