s population, industrialization, pollution, food production and resource depletion continue to remain the same on Earth with the present growth rate reached its limit in the next one hundred years. Simon, Weinrauch and Moore (1994) provides a view on the availability of natural resources contrast. They believe that the measures of resource scarcity prices, the highest price of resources are most scarce. Assessment of price trends on the basis of nonrenewable natural resources, the real key (adjusted for inflation), they concluded that these prices show a downward trend, the people cast doubt on the conclusions reached in The Limits to Growth. Similarly, the Nordhaus (1992), the real resource price data did not show a major turning point of scarcity.Recently, in a broader concept of carrying capacity of the environment has been added to the list of issues of sustainable development. The carrying capacity is the biological limit the ability to support human activities in the environment. For example, the service environment provides many of the renewable or renewable, but if the usage exceeds the rate of natural regeneration may be depleted due to excessive use. In fact, represents the ultimate bearing capacity of the dependence of society caused by the growth (above) to use nonrenewable and renewable resources. Some people believe that the Earth39。s sustainable development objectives, we believe that an economy can be sustained when the economic wellbeing and happiness of future generations to maximize. Such as clothing and food, however, beyond the traditional view of economic wellbeing of the modity economy and services, such as the services provided by the environment on the market, including goods and services often do not have to buy and sell (for example, entertainment, safe drinking water and landscape).In order to reflect the needs of future generations, the sustainability is the generation of economic wellbeing. The wellbeing of present and future generations is linked to the traditional concept of capital (for example, buildings and machinery) to be expanded to include farmlands, forests, lakes, rivers, estuaries, (natural capital) wetlands the Aldy Hrubovcak and Vasavada 1998. From an economic point of view, this definition of sustainability, need a bination of the appropriate number of artificially produced and natural capital for social investment to ensure that the market and nonmarket goods and services. This includes not only the different types of capital, direct investment, and investment in technical research and development (R amp。s needs (World Environment and Development Council, 1987).Since then, the Sustainable Development has called for different, often unrelated interest groups. According to the GrahamTomasi 1991, ... almost everyone in the sustainable development of the trend of sustainable development means that all passengers of all things (). For example, Murcott (1997) have been identified since the definition of 57 in 1979, sustainable development.
