How environmental pollution can influence social welfareEnvironmental quality has an undefined impact on quality of life and various indicators are used to show regional variations in aspects, such as water quality . There are many measures of environmental quality, but is only for quality of life. Moreover, the measurement of societal welfare is important. Societal welfare is not simply, the sum of the parts, but varies depending on the individual in which people find themselves at any time in their life. In principle, it should be possible to apply weights to each element of societal welfare, but as preferences for each of these vary within the population. In the absence of a method with which everybody is satisfied, GNP and GDP are typically the most popular used measures for quality of life or standard of life. But, these are problems with the data itself to measure quality of life because quality of life is feeling or satisfaction of level to the country's citizen and it can not be seen by numbers or statistic method. For example, GDP ignores household production, such as the effort that goes into the rearing of children, the benefits that this provides for society and the public expenditure that is avoided. Neither are costs treated equally with the benefits. GDP counts all economical activities irrespective on pollution appears to increase. GDP even through it is a degree of double counting. Otherwise, environmental products are good to be measured to quality of life. For example, many environmental products are unpriced. Consequently, environmental products that people value, or which are critical to the sustainability of development, are abused or depleted because of their public products have good characteristics and the absence of a market price signal.Environmental economists try to work within the economic model to measure quality of life. Rather than questioning the link between utility and consumption or choice, the preferred approach is to add an element into the utility function that represents the value of environmental products or the stock of natural capital. By one means or another, the preservation value of these environmental products is estimated in terms of willingness to pay to protect the environment or as willingness to forego other products in return. It seems the quality of people's environment can be represented by objective indicators. At another, their interpretation will vary and can be represented by subjective indicators. Objective indicators come in two forms: (i) economic indicators and (ii) social indicators. The former depends on an ability to select the products and services that are desires, in other words, the satisfaction of preferences . The economic argument is that people select the best quality of life, who can obtain commensurate with their resources and personal desires. By comparison, social indicators are based on normative ideals on what could be considered the food life. For example, would be infant morality, literacy, crime rates and social indicators are objective measures. Both have guided, much of the research on quality of life, particularly concerning with the urban environment. Quality of life can include natural a significant influence on local quality of life, for instance, natural beauty spots used for recreation.
