Study Notes
Environment
Definition The environment refers to the natural world and all living things, including ecosystems, air, water, land, and living organisms.
Components The environment consists of:
- Abiotic factors: Non-living components, such as:
- Light
- Temperature
- Water
- Soil
- Air
- Biotic factors: Living components, such as:
- Plants
- Animals
- Microorganisms
Importance The environment provides various essential services, including:
- Supporting life: Providing air, water, food, and shelter for all living organisms
- Regulating climate: Influencing weather patterns, temperature, and precipitation
- Purifying air and water: Filtering out pollutants and toxins
- Providing resources: Offering natural resources, such as minerals, fossil fuels, and timber
Environmental Issues Major environmental concerns include:
- Climate change: Rising global temperatures and associated impacts
- Pollution: Contamination of air, water, and land
- Deforestation: Clearance of forests, resulting in loss of biodiversity and ecosystem disruption
- Conservation: Preservation and protection of natural resources and ecosystems
Human Impact Human activities significantly affect the environment, leading to:
- Habitat destruction: Human-induced changes to natural habitats, causing loss of biodiversity
- Resource depletion: Overexploitation of natural resources, leading to scarcity
- Environmental degradation: Pollution, climate change, and other negative environmental impacts
