Quality of Neighborhood Development . . . Areas surrounding a location are investigated to determine whether incompatible racial and social groups are present, for the purpose of making a prediction regarding the probability of the location being invaded by such groups. If a neighborhood is to retain stability, it is necessary that properties shall continue to be occupied by the same racial classes. A change in social or racial occupancy generally contributes to instability and a decline in values.

We conclude that every [developing] municipality must, by its land use regulations, presumptively make realistically possible an appropriate variety and choice of housing. More specifically, presumptively it cannot foreclose the opportunity . . . for low- and moderate-income housing and in its regulations must affirmatively afford that opportunity, at least to the extent of the municipalitys fair share of the present and prospective regional need therefor.

By environment, I mean not just land or housing, but air and water, flowers and green trees. There is a real sense in which clean air belongs to everyone, a sense in which green trees and flowers are everyones right to see and smell. The right to enjoy these is connected to a citizens right to life, to pursue his own happiness as he sees fit provided his pursuit does not infringe anothers rights.
