Environmental science encompasses various specialized fields, each focusing on different aspects of the environment. Here are some key types of environmental science:

1. **Ecology:**
 - Studies the interactions between organisms and their environment.
   - Explores ecosystems, populations, and the distribution of species.

2. **Environmental Chemistry:**
   - Examines the chemical processes in the environment.
   - Investigates the presence and effects of pollutants in air, water, and soil.

3. **Atmospheric Science:**
   - Focuses on the Earth's atmosphere and climate.
   - Studies weather patterns, atmospheric composition, and climate change.

4. **Geosciences:**
   - Includes disciplines like geology, meteorology, and oceanography.
   - Explores the Earth's physical structure, processes, and natural resources.

5. **Environmental Biology:**
   - Examines the impact of environmental factors on living organisms.
   - Studies biodiversity, conservation, and adaptation to changing environments.

6. **Environmental Engineering:**
   - Applies engineering principles to address environmental issues.
   - Designs solutions for waste management, pollution control, and sustainable resource use.

7. **Environmental Policy and Management:**
   - Focuses on developing and implementing policies to address environmental challenges.
   - Examines the social and political aspects of environmental issues.

8. **Environmental Health:**
   - Investigates the impact of environmental factors on human health.
   - Studies air and water quality, toxicology, and disease prevention.

9. **Conservation Biology:**
   - Aims to preserve and protect biodiversity.
   - Focuses on strategies for wildlife conservation and habitat restoration.

10. **Environmental Economics:**
    - Examines the economic aspects of environmental issues.
    - Analyzes the costs and benefits of environmental policies and sustainable practices.

11. **Hydrology:**
    - Studies the distribution, movement, and properties of water.
    - Examines water resources, including rivers, lakes, and groundwater.

12. **Environmental Sociology:**
    - Investigates the social aspects of environmental issues.
    - Explores how human societies perceive and respond to environmental challenges.

These interdisciplinary branches collectively contribute to our understanding of the environment and play a vital role in addressing the complex environmental issues facing our planet.
