Since the 1970s, the concept of environmental protection has been popular. It argues that the ability of individual habitats to sustain human existence without severe environmental destruction is constrained by necessity. Because of its extravagant room use, prime agriculture property, water availability, water contamination and other consequences the suburban sprawl is known to be unsustainable. Decline in metropolitan areas is seen as a product of suburbanization and growth. Revitalization of core towns was encouraged as a way to divert expansion from suburbs to central towns. Environmentalists and some community designers proposed that older city centres can be revitalised and used to address ongoing urban demands, rather than under-used, deteriorating slums. This paper discusses several tools for calculating environmental protection. Multiple regression analysis, panel data analysis and delphi approaches are among them.
