History
Environmental science emerged in the 20th century as a distinct academic discipline. It was developed in response to the growing public concern about the impact of human activities on the environment. The roots of environmental science can be traced back to the works of early naturalists and philosophers who observed and studied the natural world.

Scope and Importance
Environmental science covers a wide range of topics, from the study of various earth systems and their complex interactions to the impact of human activities on these systems. It also involves the study of the biological, chemical, and physical processes that take place in the environment and their effects on biodiversity and sustainability.
