Environmental science

Environmental science is the systematic study of the natural environment, its processes, and the impact of human activities on the environment, to preserve and improve the quality of life on Earth.

Environmental science is an interdisciplinary field that studies the interactions between the physical, chemical, and biological components of the environment and how humans affect these systems. It integrates knowledge from biology, chemistry, geology, physics, and social sciences to understand natural phenomena, ecosystem dynamics, and human impacts on the planet.

The environment is composed of biotic (living) and abiotic (non-living) elements. Biotic components include all living organisms like plants, animals, and microorganisms, while abiotic components consist of physical and chemical factors such as air, water, soil, climate, and minerals. The major spheres of the environment are the atmosphere (gases), hydrosphere (water), lithosphere (rocks and soil), and biosphere (life).
