Development and Environment
The Millennium Development Goals (MDGs, 2000–2015), an eight-goal UN framework targeting poverty, education, and health, were succeeded by the Sustainable Development Goals (SDGs, 2015–2030) — 17 goals balancing economic growth, social inclusion, and environmental protection, adopted by all UN member states.
Human and Environment Interaction
Anthropogenic activities — those caused by human action, such as industrialisation, deforestation, urbanisation, and intensive agriculture — alter natural ecosystems, deplete resources, and are the primary drivers of contemporary environmental change, including climate change.
Environmental Issues: Local, Regional and Global
| Type of pollution | Key sources |
|---|---|
| Air | Vehicular emissions, industrial exhaust, biomass burning |
| Water | Industrial effluents, sewage, agricultural runoff |
| Soil | Pesticides, chemical fertilisers, improper waste disposal |
| Noise | Traffic, industry, construction, loudspeakers |
Categories of waste
Solid, liquid, biomedical, hazardous, and electronic (e-waste) — each requiring a different, regulated method of collection, treatment, and disposal.
Climate change
The long-term shift in global temperature and weather patterns, driven largely by greenhouse gas emissions, carries socio-economic dimensions (food and water security, migration, livelihoods) and political dimensions (international negotiation over responsibility and mitigation targets).
Impacts of Pollutants on Human Health
Air pollution is linked to respiratory and cardiovascular disease; contaminated water to gastrointestinal and vector-borne diseases; soil contamination to bioaccumulation of toxins in the food chain; and noise pollution to hearing loss and stress-related disorders.
Natural and Energy Resources
Renewable: Solar, Wind, Hydro, Geothermal, Biomass. Non-renewable: Nuclear (technically low-carbon but fuel-limited) and fossil-fuel-based sources. Forests function as a resource base and as a carbon sink, making conservation doubly important.
Natural Hazards and Disasters: Mitigation Strategies
Mitigation combines structural measures (early-warning systems, resilient infrastructure) with non-structural measures (land-use planning, community preparedness, insurance), guided in India by the National Disaster Management Authority framework.
