Introduction To Environmental Science

Because it draws from a wide range of disciplines, including chemistry, physics, medicine, life sciences, public health, agriculture, sanitary engineering, etc., the science of environmental studies is a multi-disciplinary field. Physical phenomena in environment are studied by this science. It studies the origins, responses, transportation, effect, and demise of biological species in air, water, and soil, as well as the impact of human activities on these. The only planet in the cosmos known to have such a wide variety of life is Earth. The existence of life on the planet was only made possible by the positive interaction between biotic and abiotic factors in a way that the energy flow and biogeochemical cycle follow a well-defined course. The solid (rock/soil), liquid (water), and gaseous (air) aspects of the planet earth are represented by distinct spheres. The biosphere refers to the region where these three spheres meet and support life.
