NCERT Class 11 Sociology Understanding Society: Chapter 3 — UNDERSTANDING SOCIETY
This chapter, "Environment and Society," from NCERT's Understanding Society for Class 11, explores the intricate relationship between human societies and the environment.

The chapter defines ecology as the web of physical and biological systems, emphasizing that both nature shapes society and society shapes nature. It discusses how human interventions, from deforestation to climate change, modify ecological processes, often blurring the lines between natural and human-induced environmental changes.
