Study Notes
Learning Objectives
- Describe the environment
- Differentiate the components and types of environment
- Describe the basic concepts of how human actions affect the environment
- Explain the importance of understanding the interactions between human activities and the environment
- List and briefly explain common positive and negative effects of human activities on the environment
- Appreciate the importance of the environment by citing at least two ways to save the environment
Overview
- Human impact on the environment has been a long-discussed topic
- Technological advancements have positively affected standards of living and life expectancy
- Pollution (industrial activity, transportation, agriculture) is the most significant negative impact
- Leading to environmental problems (climate change, acid rain, and habitat destruction)
- Environment provides essential resources (clean air, water, fertile land)
- Source of inspiration in art, philosophy, and science
- Faced unprecedented challenges in recent decades due to human activities
- Population growth and technological advancements have increased interactions with the environment
- Shared responsibility to protect, preserve, and nurture the environment
Physical Components
- Atmosphere: The gaseous envelope surrounding Earth, primarily nitrogen and oxygen. Includes weather patterns, climate, and air quality. Influences temperature, wind patterns, and atmospheric conditions
- Hydrosphere: All the water on Earth (oceans, seas, rivers, lakes, and groundwater). Crucial for supporting life, regulating climate, and shaping Earth's surface through erosion and sedimentation
- Lithosphere: The solid Earth consisting of the Earth's crust, mantle, and core. Forms the foundation for landforms, geological features, and Earth's physical structure
- Cryosphere: The frozen component of Earth's surface including polar ice caps, glaciers, and permafrost. Influences climate and sea levels
Biological Components
- Biota: Collective term for all living organisms within the biosphere (plants, animals, microorganisms, fungi, and bacteria). Interact with each other and physical surroundings, shaping ecosystems and overall environmental health
- Ecosystems: Dynamic communities of living organisms and their physical environment; vary from deserts to rainforests, influenced by biota and physical factors of the region
- Biodiversity: Variety of life on Earth, including the number of species, their genetic diversity, and the variety of ecosystems they form. Crucial for ecosystem resilience and stability
Types of Environment
- Geographical (natural): Earth's surface, rivers, mountains, deserts, land, water, oceans, and volcanoes
- Man-made (built): Buildings, roads, bridges, infrastructure, and other human-made structures. Designed and constructed for various purposes
Functions of the Environment
- Supplies resources: for production (renewable and non-renewable)
- Sustains life: necessary resources (sun, soil, water, air) and biodiversity
- Assimilates waste: processes waste generation and disposal (garbage).
- Enhances quality of life: beauty of nature
Human Impact on the Environment
- Negative impacts: Climate change, deforestation, air pollution, water pollution, loss of biodiversity, ocean pollution, and soil degradation.
- Positive impacts (to reduce, reuse, recycle, renewable energy, etc): Renewable energy, reforestation and afforestation, reduce plastic use, environmental regulations, community initiatives, clean technologies
Protecting Biodiversity
- Overpopulation and waste management
- Ways to help save the environment: reduce, reuse, recycle; conserve energy, use renewable energy; sustainable transportation; water conservation; green practices; plant trees; reduce meat consumption; education and advocacy
Climate Change: Mitigation and Adaptation
- Global warming and CO2 emissions
- Impacts on health, infrastructure, food, and water security
- Require measures to mitigate effects and adapt to consequences (e.g., transitioning to cleaner energy sources)
Additional Notes
- Various other negative effects of technology on the environment (emissions, resource depletion, hazardous waste)
- Technologies that also help the environment (smart appliances, electric vehicles, renewable energy)
- Conservation devices to reduce environmental impact
- What biodiversity is
- Causes of biodiversity loss (habitat loss, fragmentation, overhunting, overfishing, invasive species and pollution)
- Effects of biodiversity loss
- Why biodiversity is important
