Field of knowledge that studies of how humans and other species interact with one another and with the nonliving environment. It is both a physical and social science that integrates knowledge from a wide range of disciplines, including physics, chemistry, biology, geology, geography, economics, political science, sociology, psychology, and philosophy.

The branch of science concerned with environmental issues.

Study of how we and other species interact with one another and with the nonliving environment (matter and energy). It is a physical and social science that integrates knowledge from a wide range of disciplines, including physics, chemistry, biology (especially ecology), geology, geography, resource technology and engineering, resource conservation and management, demography (the study of population dynamics), economics, politics, sociology, psychology, and ethics.

the branch of biology concerned with the relations between organisms and their environment

The systematic, scientific study of our environment as well as our role in it.

The scientific study that uses biological principles to look at the relationships between humans and their environment.

Scientific study of environmental issues. It is important to achieve objectivity and the best possible solution to environmental science is a developing branch of science, which studies the environmental impacts of products, processes and their alternatives. It includes life cycle analysis, which examines the environmental impact of products from their cradle to the grave.

Environmental science is the study of the interactions among the physical, chemical and biological components of the environment; with a focus on pollution and degradation of the environment related to human activities; and the impact on biodiversity and sustainability from local and global development. It is inherently an interdisciplinary field that draws upon not only its core scientific areas, but also applies knowledge from other non-scientific studies such as economics, law and social sciences. Physics is used to understand the flux of material and energy interaction and construct mathematical models of environmental phenomena.
