Environmental Science is an interdisciplinary field that studies the interactions between the physical, chemical, and biological components of the environment. It integrates knowledge from various scientific disciplines, including biology, ecology, geology, atmospheric science, chemistry, and social sciences, to understand how natural systems function and how human activities impact the environment. The goal of environmental science is to address environmental challenges such as climate change, pollution, biodiversity loss, and resource depletion, and to develop sustainable solutions that promote the health of ecosystems and human livelihoods. This field involves research, data analysis, and the application of scientific principles to inform policy and management decisions aimed at protecting the environment and promoting sustainability.
