Pollution and Sustainable Development

Overview

Pollution and sustainable development is a high-weightage topic in KAR TET Environmental Studies, appearing consistently in both Paper I and Paper II. This topic tests your understanding of how human activities degrade the environment and what measures can restore balance between development and ecological health.

For the exam, you must know the causes, effects and control measures of all four pollution types—air, water, soil and noise. Equally important is understanding sustainable development as a concept that links economic growth with environmental protection. Questions often connect pollution sources to local Karnataka contexts (industrial belts like Bhadravati, mining in Bellary, traffic in Bengaluru) and expect you to suggest practical solutions suitable for primary-level teaching.

Mastering this topic also supports your pedagogy answers—many EVS questions ask how to teach pollution awareness through activities, projects and local environmental observations.

Key Concepts

• **Pollution** is the introduction of harmful substances (pollutants) into the environment that cause adverse changes to air, water, soil or living organisms.

• **Air pollution** results primarily from vehicular emissions, industrial discharge, burning of fossil fuels and agricultural stubble burning; key pollutants include CO, CO₂, SO₂, NO₂, particulate matter (PM2.5, PM10) and lead.
