Sustainable Development: Tenant Theory
In the past 10,000 years, mankind was primarily engaged in agriculture and animal husbandry. Its economic development did not cause too much destruction of the Earth's environment. But in the recent 300 years, coal mining, oil extraction, land reclamation, mineral exploitation, lumbering, fishing, chemical and nuclear industries, etc., resulted in a variety of ecological disasters. The atmosphere and water resources, soil layers have been seriously polluted. The deteriorating environment reminds mankind that economic development can not sacrifice the environment. For the sake of sustainable development, this paper puts forward a new theory: Tenant Theory. This theory regards mankind as a tenant living in the big house, the biosphere. Its vertical distance is only about 20 kilometers. All the activities of the tenant could not destroy the house. But, this tenant has always been damaging the house unconsciously. In order to obtain an opportunity of sustainable development, mankind must adjust its values and patterns of behavior. This theory is first presented in this paper, it warns that mankind should recognize own place in the great nature, and know how to think and how to behave so as to obtain sustainable development.
