Document Summary
The environment includes not only the living, but the nonliving things around us. We depend on a healthy functioning planet, it surrounds us. Fundamental insight of environmental science: our interactions with the planet matter. Natural resources: substances and energy sources needed for survival. We rely on ecosystem services, which are services that arise from the normal functioning of natural systems. Resource consumption exerts social and environmental pressures. Ecological footprint: the environmental impact of a person or population. Overshoot: humans have surpassed the earth"s capacity to support us. Millennium ecosystem assessment--population and consumption drive impact. Environmental scientists find connection between people, earth"s function, and their impacts on each other. Solutions to problems are applications of environmental science. People vary in how they perceive environmental problems. Ddt is still used in africa, because it is not perceived as a bad problem. Science is an accumulated body of knowledge, that arose from a dynamic process of observation, testing, and discovery.
