Environmental Pollution & Economy

Introduction

In India, groundwater and air pollution are increasing.
According to the Parliamentary Committee Report (2026–27):
Groundwater pollution in 8 states
Toxic metals such as Mercury, Uranium, and Cadmium have been detected.

1. Environmental Economics

Human activities → Environmental impact is the core idea of environmental economics.
This is covered in the 12th standard syllabus.

Here:
Industrial waste + chemicals → Water pollution
Vehicle emissions → Air pollution

2. Externalities

Definition: An activity of a person or firm that imposes a cost on others.

Here:
Industrial discharge of waste water → Affects rural people

This is called a Negative Externality.

3. Public Goods / Common Resources

Definition: Resources used by everyone.

Air
Water

11th standard concept:
Scarcity and misuse of resources → Problems

4. Cause → Effect

Causes:
Excess groundwater extraction → Drying of water sources
Industrial waste → Heavy metal contamination
Chemicals (Fertilizer, Nitrate, Fluoride) → Toxic drinking water
Vehicles and industries → Air pollution

Effects:
Health issues (diseases, respiratory problems)
Impact on human capital
Economic impact
Agricultural impact

5. Health and Human Capital Impact

Toxic drinking water → Diseases
Air pollution → Respiratory diseases

12th standard concept:
Healthy population → Higher productivity
Diseases → Lower productivity

6. Economic Impact

Reduction in work efficiency
Increase in healthcare expenditure
Impact on GDP growth

7. Agricultural Impact

Polluted water → Decline in soil quality
Reduction in crop yield

8. International Dimension

According to the IQAir report:
India, Pakistan, and Bangladesh are among the countries with high air pollution.

This is a Global Environmental Issue.

9. Solutions

Government measures:
Water purification schemes
Pollution control laws

Economic tools:
Pollution Tax
Subsidy for clean technology

Sustainable Development:
Meeting present needs while protecting future generations

10. Exam Points

Externality – Negative
Public Goods – Air, Water
Sustainable Development
Human Capital Impact
Pollution → Economic Loss

Summary

Water and air pollution
affect human health
economic growth
and the environment

Therefore,
Environmental protection = Economic development is an important concept.
