EEES Unit 5
Social Issues and the Environment

1. Sustainable Development

Sustainable development means development that fulfills present needs without affecting the ability of future generations to fulfill their needs.

Features:

• Conservation of resources
• Environmental protection
• Economic growth
• Social welfare

Importance:

• Reduces pollution
• Conserves biodiversity
• Maintains ecological balance
• Supports long-term development

2. Urban Problems Related to Energy

Urban areas face many energy-related problems due to population growth, industrialization and increased use of vehicles.

• Increasing energy demand
• Air pollution
• Traffic congestion
• Waste generation

Solutions:

• Use renewable energy
• Promote public transport
• Use energy-efficient buildings
• Practice energy conservation

3. Water Conservation

Water conservation means efficient use, protection and management of water resources.

• Reduce wastage of water
• Reuse wastewater
• Use efficient irrigation methods
• Protect water bodies

4. Rainwater Harvesting

Rainwater harvesting is the collection and storage of rainwater for future use.

Methods:

• Rooftop rainwater harvesting
• Surface runoff harvesting

Advantages:

• Recharges groundwater
• Reduces flooding
• Provides water during drought
• Reduces pressure on municipal water supply

5. Watershed Management

Watershed management means conservation and management of water and land resources in a watershed area.

Objectives:

• Soil conservation
• Water conservation
• Flood control
• Groundwater recharge

Methods:

• Afforestation
• Check dams
• Contour farming
• Proper drainage management

6. Climate Change

Climate change refers to long-term changes in temperature, rainfall, wind patterns and other climate conditions.

• It affects agriculture.
• It causes extreme weather events.
• It affects biodiversity.
• It can increase sea levels.

7. Global Warming

Global warming is the increase in Earth’s average temperature due to greenhouse gases.

Causes:

• Burning of fossil fuels
• Deforestation
• Industrial emissions
• Increase in greenhouse gases

Effects:

• Rising sea levels
• Extreme weather conditions
• Loss of biodiversity
• Melting of glaciers

Control Measures:

• Use renewable energy
• Afforestation
• Energy conservation
• Reduce fossil fuel use

8. Acid Rain

Acid rain occurs when sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere and form acids.

Effects:

• Damage to crops
• Soil degradation
• Corrosion of buildings
• Harm to aquatic life

Control Measures:

• Reduce industrial emissions
• Use clean fuels
• Install pollution control devices
• Control vehicle emissions

9. Environmental Protection Act, 1986

The Environment Protection Act, 1986 provides a framework for environmental protection and pollution control.

• Prevents environmental pollution
• Controls hazardous substances
• Gives power to authorities for environmental protection
• Supports sustainable development

10. Other Environmental Legislations

• Air Prevention and Control of Pollution Act: Controls air pollution and emissions.
• Water Prevention and Control of Pollution Act: Prevents water pollution and controls industrial discharge.
• Wildlife Protection Act: Protects wild animals and plants.
• Forest Conservation Act: Prevents deforestation and protects forests.

11. Environmental Ethics

Environmental ethics deals with the moral relationship between humans and environment.

Principles:

• Respect nature
• Conserve resources
• Prevent pollution
• Protect biodiversity

12. Consumerism and Waste Products

Consumerism increases demand for products, which leads to resource depletion and waste generation.

Problems:

• Plastic waste
• Resource depletion
• Environmental pollution
• Increase in solid waste

Solutions:

• Recycling
• Sustainable consumption
• Reuse products
• Follow Reduce, Reuse and Recycle principle

13. Public Awareness

Public awareness helps people understand environmental issues and encourages them to protect the environment.

Methods:

• Education
• Media campaigns
• Environmental programs
• Community participation

Importance:

• Encourages conservation
• Reduces pollution
• Protects natural resources
• Promotes sustainable lifestyle
