The significance of environmental sustainability in the UPSC syllabus is paramount, as it reflects a global concern over ecological balance and climate change. Candidates must delve into topics like biodiversity conservation, sustainable development goals (SDGs), and India’s environmental policies. Understanding the impact of environmental degradation on socio-economic development and health enables candidates to address current challenges effectively. This knowledge not only aids in preparing for general studies papers but is also crucial for the essay paper and interview topics focusing on sustainability issues.
