Leopold writes, “Land, therefore is not merely soil, it is a fountain of energy flowing through a circuit of soils, plants, and animals.” Food chains are the living channels that conduct energy upward; death and decay brings it back to the same soil. The circuit is not closed; it is an ongoing process, which must remain open. Some energy is dissipated in decay and some is added by absorption from air. The velocity and character of the upward flow of energy depends on the complex structure of the plants and animals community. This interdependence between the complex structure of the land and its smooth functioning as energy unit is one of its basic attributes. When a change occurs in one part of the circuit, many other parts have to adjust themselves to the new changes. In environment the changes are part of the evolutionary process. Such changes are usually slow and local.

Whereas man made changes are violent and rapid with tools such changes destabilize the natural circuit. Man’s invention of tools has enabled him to make changes of unprecedented violence, rapidity, and scope. Mankind is proud of their achievements and progress through science and technology. Unfortunately, they have forgotten scale of their changes, which might affect the environment much beyond their limit. For example, if the fossil fuel remains expensive we would be forced to limit our vehicular movements. But with the help of new discoveries fuel-efficient engines would certainly attract a larger number of customers to buy motor vehicles. In result, the total use of fossil fuel is surely going to increase in short period of time. The present economic strategy encourages such technique to expand the consumer’s market. Therefore, as member of the biotic society, Industrial Designers have enormous responsibility in pursuing the spirit of ethical responsibility through the design process. Each design solution should have strong ethical considerations that would reflect the true intensions and sincere effort.
