Environmental issues in the UPSC syllabus require careful consideration since they encompass critical topics like sustainable development, biodiversity, and climate change. Candidates need to understand both the policies associated with environmental governance and their impact on human welfare. This understanding is essential for both preliminary and mains examinations, as environmental topics have significant implications for public administration. Moreover, integration with subjects like geography and agriculture allows for a comprehensive approach, highlighting the interconnectedness of these issues within national and global contexts.
