Environmental science involves a scientific study where interactions and relations of biological, physical, and chemical components of the environment happen. It is therefore, multidisciplinary in nature that provides a broad area of environmental study. Interactions happen between the living things and non-living constituents of the environment as well as with the environment itself. Currently it has emerged to be an interdisciplinary subject comprising of life science, earth science, and social science. Environmental science has also provided an integrated, interdisciplinary, and quantitative measure to the study of environmental systems. Environmental science is classified in to three parts that are the physical environment, biological environment and cultural environment.
There are various component of environmental science. One of the components is Atmospheric Sciences, which examines the phenomenology of the Earth's gaseous outer layer. It is made up of meteorological studies, atmospheric dispersion modeling and greenhouse gas phenomena. For a long time, environmental science has been on stage to look at the impact of human beings on the environment which has been important for economic growth, as well as socio-political ramifications. Many environmental scientists have given out various importance of environmental science which is mainly for the economy welfare of human society.
Geoscience is another component of environmental science that examines on geology of our surrounding such as environmental soil science, volcanic phenomena and the earth crust evolution. To some extend geosciences encompass the oceanography and hydrology of our environment.
Ecological component analyzes the dynamics of biological population and some aspects of the environment to a deeper extend. It is this component of environmental science that conducts environmental impact assessments (IA) our immediate surrounding hence involved in issues such as water quality, conservation, climate change and the use of natural resources such as waste management, sustainable development, disaster reduction and pollution of our environment at large.
