The Environment: A Balanced System
The environment consists of both biotic (living) and abiotic (non-living) components. Human activities have disrupted the natural balance of these components, leading to several critical environmental problems.
Major Environmental Issues
- Pollution: Contamination of air, water, and soil by harmful substances.
- Global Warming: The gradual increase in the Earth's average temperature due to greenhouse gases.
- Desertification: The process by which fertile land becomes desert, often due to deforestation and poor agricultural practices.
- Loss of Biodiversity: The extinction of various plant and animal species due to habitat destruction.
