Changes in perception of environment in different stages of human civilization
Answers
Explanation:
Research on the human dimensions of global change concerns human activities that alter the Earth's environment, the driving forces of those activities, the consequences of environmental change for societies and economies, and human responses to the experience or expectation of global change. Such research is essential both to understand global change and to inform public policy.
Research on the human causes of global change has shown that socioeconomic uncertainties dominate biophysical uncertainties in climate impacts and possibly also in other impacts of global change. It has shown that human activities, such as deforestation and energy consumption, are determined by population growth, economic and technological development, cultural forces, values and beliefs, institutions and policies, and the interactions among all these things. Ongoing research is improving our understanding of the dynamics of several of these driving forces. It has shown, for example, that human interactions with the environment do not necessarily lead to a “tragedy of the commons” and has begun to enumerate the necessary conditions for successful long-term environmental resource management. Research on the human consequences of global change shows that they are due at least as much to the social systems that produce vulnerability as to environmental changes themselves. This work is refining estimates of impacts and identifying major sources of vulnerability. Research on
