Study Notes
Introduction to Environmental Science
- Environment: Derived from the French word environner, meaning to surround; refers to the physical, living, and non-living surroundings of a society with reciprocal relationships.
- Importance of the environment includes providing resources, amenity services, life support, and waste receptacles.
Functions of the Environment
- Source of resource inputs essential for human survival and development.
- Ecosystem services contribute directly and indirectly to human well-being.
Ecosystem Services
- Provisioning Services: Goods harvested from nature, e.g., food, water, wood, fuel.
- Regulating Services: Climate regulation, flood management, water filtration.
- Cultural Services: Health and well-being benefits through recreation, education, and spiritual connections.
- Supporting Services: Indirect benefits necessary for producing other ecosystem services, e.g., nutrient cycling, soil formation.
Resources from the Environment
- Renewable Resources: Can regenerate quickly, e.g., solar energy, wind, water.
- Nonrenewable Resources: Limited and cannot replenish at consumption rates, e.g., coal, petroleum.
Seven Environmental Principles
- Nature knows best; all forms of life are important.
- Everything is interconnected; environmental change is inevitable.
- All matter must go somewhere; Earth has finite resources.
- Nature's beauty highlights humans' responsibility as stewards of creation.
Environmental Science Overview
- Integrative field combining multiple scientific disciplines to understand complex environmental systems.
- Global in scope, emphasizing resource interdependence and shared environmental challenges.
- Aims to learn how the natural world functions, human interactions with the environment, and methods to mitigate human impact.
Global Environmentalism
- Social movement focused on environmental welfare, emphasizing resource conservation and address major environmental challenges.
Historical Roots and Reasons for Global Environmentalism
- Prominent figures like Gifford Pinchot and Theodore Roosevelt promoted sustainable resource management and established national parks to protect natural resources.
- Ethical concerns about aesthetic values of nature led to the preservation movement, championed by John Muir and Aldo Leopold.
- Social progress linked to environmental quality, highlighted by Barry Commoner's interconnected ecological laws.
Persistent Environmental Challenges
- Clean Water: 1.1 billion people lack access to safe drinking water.
- Air Quality: Over 2 billion metric tons of pollutants released annually.
- Human Population Challenges: 850 million undernourished people face food shortages.
- Biodiversity Loss: 800 species extinct, with 10,000 threatened and significant forest depletion.
- Marine Resources: Over 75% of monitored fish stocks severely depleted.
The Tragedy of the Commons
- A concept introduced by Garrett Hardin in 1968 illustrating the conflict between individual interests and the common good in resource usage.
Overcoming Environmental Challenges
- The three pillars of sustainability: Environmental, Economic, and Social Sustainability ensure balanced development for future generations.
Environmental Sustainability
- Focuses on conservation, pollution reduction, and climate change mitigation to ensure natural resource preservation.
Economic Sustainability
- Emphasizes environmentally-friendly growth, job creation, fair trade, and innovative solutions for sustainable practices.
Social Sustainability
- Aims to enhance social equity, inclusion, health, and educational opportunities to support overall community well-being.
