People and Environment Interaction

  • Human Environmental Interactions can be defined as interactions between the human social system and (the “rest” of) the ecosystem.

  • Human social systems and ecosystems are complex adaptive systems (Marten, 2001). Complex because ecosystems and human social systems have many parts and many connections between these parts. Adaptive because they have feedback structures that promote survival in a constantly changing environment.

  • Human social system in order to analyses Human Environmental Interactions it is important to be aware of specific characteristics of the human social system. The type of society strongly influences people’s attitude towards nature, their behavior and therefore their impact on ecosystems.

  • Important characteristics of human social systems are population size, social organization, values, technology, wealth, education, knowledge and many more. Especially values and knowledge strongly influence peoples “view of life” and consequently define the way people act. The choice of possible actions is then limited by the available technology.

  • People modify the environment for their purposes and obtain benefits (Ecosystem Services) from it. These Ecosystem Services are essential for human well-being and include.

  • For example the provision of resources like water, timber, food, energy, information, and land for farming and many more. Obviously by using these resources people affect the environment in a lot of ways. Furthermore people often reorganize existing ecosystems to achieve new ones that seem to be more effective in serving their needs.

  • The Drivers-Pressures-State-Impact-Response (DPSIR) model was originally developed by the European Environmental Agency (EEA) and is used to assess and manage environmental problems. Many national and European institutions adopted this conceptual framework.

  • It identifies the various causal chains of links between human activities and environmental degradation. The model distinguishes several categories of indicators in order to explain how the state of the environment is changed due to human activities.

  • Human activities increase or mitigate pressure on the environment. The driving forces which initiate human activities are mainly socio-economic and socio-cultural forces.

  • Students will demonstrate the following enduring understanding.

  • People rely on the environment to fulfill a variety of needs, including food, shelter, and energy.

  • Environment and economic needs both determine how people choose to use lands.

  • Recognize the difference between renewable and nonrenewable resources.

  • Water is just one example of a natural resource, or a useful material found in the environment. People depend on many kinds of natural resources.

  • Renewable resources are resources that Earthy or people can replace.

  • Nonrenewable resources are a resource that cannot be replaced in a relatively short period of time if at all.

  • Fossil fuels are nonrenewable resources formed over millions of years from the remains of plants and animals.

  • Coal natural gas, and petroleum are important fossil fuels. When nonrenewable resources are used up, they are gone.

  • People try to increase the positive and decrease the negative effects of using resources.

  • For example, using a resource might lead to economic growth but also create pollution that needs to be reduced.

  • Working together, people, governments, and businesses these wind turbines in Canada can try to use resources wisely. Convert wind energy into electricity.

  • Sources of energy are important for human activity. Some resources, such as wind and sunlight are renewable.

  • Today, we mostly rely on nonrenewable energy resources such as coal and petroleum. Because these resources are nonrenewable, Earth will eventually run out of them.
