- Atmosphere: The layer of gases surrounding Earth, essential for climate and weather regulation.
- Hydrosphere: Comprises all water bodies like oceans, rivers, lakes, and groundwater.
- Lithosphere: The Earth's outer crust containing soil and minerals.
- Biosphere: The global sum of all ecosystems, including all living beings and their relationships.

The built environment refers to human-made surroundings that provide the setting for human activity. These include:
- Urban Areas: Cities and towns characterized by dense human populations and vast human-made structures.
- Infrastructure: Roads, bridges, airports, and other essential facilities and systems serving a country or area.
- Buildings: Residential, commercial, and industrial structures where humans live and work.
- Industrial Areas: Zones designated for manufacturing and other heavy industries.

This category examines how humans interact with the natural environment and the built environment. Key areas include:
- Environmental Impact: The effect of human activities on natural ecosystems, including pollution, deforestation, and climate change.
- Sustainable Development: Meeting the needs of the present without compromising the ability of future generations to meet their own needs.
- Resource Management: Efficient and sustainable use of natural resources like water, minerals, and forests.
- Conservation Efforts: Initiatives aimed at protecting and preserving natural environments and wildlife.

Governments and international organizations have established policies and laws to regulate human impact on the environment. Important aspects include:
- Environmental Protection Acts: Legislation aimed at conserving natural resources and reducing pollution.
- International Agreements: Treaties and protocols like the Paris Agreement that address global environmental issues.
- Regulatory Bodies: Organizations responsible for enforcing environmental laws and regulations.
- Sustainability Initiatives: Programs designed to promote eco-friendly practices and renewable energy sources.
