Nature can be seen as beautiful and harmonious but it also inspires fear in man who has had to fight it in order to survive. Nowadays, nature is threatened by man who has become detached from it. Technology has endowed humans with the power of a major geological agency, which may act on a continental or even planetary scale (e.g. acid rain, photochemical smog, radioactive contamination, stratospheric ozone depletion, climate change). These man-made environmental problems cannot all be solved by technology alone.As human population growth, technology, pollution and demands on finite resources begin to tax the earth’s capacity. A fundamental change in man’s attitude toward the environment and most important of all, an ethical basis for the necessary legal and incentives is required for the man to avoid self-destruction in the environment. According to Blackstone (1974), the main cause of environmental crisis is mistaken values and attitudes, which are “the attitudes that we can exploit the environment without restrictions, that the production of goods is more important than the people who use them, that nature will provide unlimited resources, that we have no obligation to future generations to conserve resources, that continued increases in human population is desirable and that the right to have as many children as one wants is an inviolate right, that the answer to the problems of technology is more technology, and that gross differences and inequities in the distribution of goods and services are quite acceptable”.
