Identify two ways in which environmental psychologists work to improve the physical environment,and describe how they are helpful.

Two ways in which environmental psychologists work to improve the physical environment are through social design and defensible space.
Social design is a process by which any building (e.g.,office,school,residence,factory,retail store,or prison)may be designed in collaboration with those who will actually use that building so that it is more user-friendly,as opposed to being designed solely by an architect who will never use the building.Outdoor spaces,such as streets and plazas,can also be designed either to support human interaction or to ignore it.
Defensible space represents a way of fighting crime through careful arrangement of the physical aspects of communities,retail buildings,and residences.The way in which a building or community is designed can encourage or discourage burglars,robbers,and vandals.
