GEOGRAPHY STANDARD 15

Essential Element: Environment and Society

How physical systems affect human systems.

The geographically informed person must understand how humans are able to live in various physical settings and the role the physical features of those settings play in shaping human activity. Regardless of spatial scale, Earth’s surface is diverse in terms of climates, vegetation, fauna, soils, underlying geology, and topography. That diversity offers a range of environmental contexts where people can live and work. Physical systems and environmental characteristics do not, by themselves, determine the patterns of human activity; however, they do influence and constrain the choices people make.

Therefore, Standard 15 contains these themes: Environmental Opportunities and Constraints, Environmental Hazards, and Adaptation to the Environment.

To live in any physical environment, no matter how accommodating or how challenging, people must develop ways to take advantage of its opportunities and minimize its risks. If the incentives are great enough, people can adapt to the harshest of environments, often regardless of cost or risk.

A concept central to understanding environments is the idea of carrying capacity: the maximum number of animals and/or people a given area can support at a given time under specified levels of consumption without incurring significant environmental deterioration. Environments vary in their carrying capacities. Failure to recognize that reality can lead to environmental disaster. Increasingly, people are recognizing their responsibility to manage the environment in ways that are sustainable for future generations.

Humans employ evolving technologies when possible to reduce the negative effects of physical systems on human activities. However, there are trade-offs that result in unintended consequences. Dam building to control river flooding is a case in point. In some parts of the world, dams have diminished soil replenishment and increased water salinity and riverbank erosion. Environmental hazards such as hurricanes, tornadoes, earthquakes, wildfires, and flash floods also take their toll despite early warning systems, improved building design, and public education programs.

Students must understand the characteristics of physical environments in relation to human activities. Whether it is an issue of mitigating an environmental hazard or recognizing the carrying capacity of a given area, students must be able to envision the physical processes and patterns of a place as a potential home for people. Understanding these themes enables students to recognize that there are limits to growth and to weigh the challenges of environmental opportunities and constraints when they measure the effects of physical systems on human activities.
