Environmental science is an interdisciplinary science that studies the interactions between the physical, chemical, and biological components of ecosystems. Environmental science aims to understand three things: natural phenomena, how humans interact with the environment, and how humans impact their environment. Environmental science is concerned with determining the best ways for humans to interact with their environment, which has resulted in ecosystem services such as water purification, air purification, and waste product recycling. Environmental science research topics include physical, chemical, and biological aspects of the environment. The research is primarily concerned with environmental conservation and prevention.
