Study Notes
Environmental Science
Definition and Importance
- Environmental Science: the study of the natural world and the impact of human activity on the environment
- Importance: understanding the environment and our role in it is crucial for sustainable development and preservation of natural resources
Ecosystems
- Definition: a community of living and non-living things interacting in a specific environment
- Components:
- Biotic factors: living organisms (plants, animals, microorganisms)
- Abiotic factors: non-living components (light, temperature, water, soil)
- Types of Ecosystems:
- Terrestrial (forest, grassland, desert)
- Freshwater (rivers, lakes, wetlands)
- Marine (oceans, coral reefs)
Environmental Issues
- Pollution:
- Air pollution: release of harmful gases and particles into the atmosphere
- Water pollution: contamination of water bodies
- Soil pollution: contamination of soil
- Climate Change:
- Global warming: increase in average global temperature
- Causes: burning of fossil fuels, deforestation
- Conservation:
- Importance of preserving natural resources
- Methods: recycling, reducing waste, sustainable living
Biodiversity
- Definition: variety of different species of plants, animals, and microorganisms
- Importance:
- Maintaining ecosystem balance
- Providing ecosystem services (pollination, decomposition)
- Threats to Biodiversity:
- Habitat destruction
- Overexploitation of resources
- Climate change
Human Impact on the Environment
- Population growth and urbanization
- Resource depletion (water, fossil fuels, forests)
- Waste management and pollution
Sustainable Development
- Definition: meeting the needs of the present without compromising the ability of future generations to meet their own needs
- Strategies:
