Study Notes
Environmental Science Overview
- Studies interactions between humans and the Earth, addressing environmental issues and sustainability.
- Aims to understand how life has persisted for over 3.5 billion years despite environmental changes.
Principles of Sustainability
- Sustainability Defined: Meeting present needs without jeopardizing future generations.
- Solar Energy: Essential for heating the planet, photosynthesis, and electricity production; foundational for life.
- Biodiversity: Encompasses the variety of organisms and ecosystems; provides essential free services to humanity.
- Chemical Cycling: Involves the transfer of chemicals through the environment; crucial for maintaining air, water, soil, and food supplies.
Key Components of Sustainability
- Natural Capital: Refers to resources and services essential for life.
- Degradation of Natural Capital: Occurs through rapid depletion of non-renewable resources and pollution.
- Solutions: Emphasis on implementing environmental laws to manage pollution and resource use.
Pollution Sources
- Point Sources: Easily identifiable sources of pollution.
- Nonpoint Sources: Diffuse sources that are harder to trace.
Ecological Footprint
- Represents the biologically productive area required to sustain population resource use and waste absorption.
- Discusses the concept of ecological deficit, measuring the sustainability of lifestyles.
Environmental Impact Model (IPAT)
- Impact (I) is determined by the equation: I = P (Population) x A (Affluence) x T (Technology).
Causes of Environmental Problems
- Population Growth: Surging population leads to excessive consumption of resources and increased pollution.
- Unsustainable Resource Use: High levels of affluence lead to overconsumption and wastefulness.
- Poverty: Affects one in five individuals globally; relates to an inability to meet basic needs like food and shelter.
- Excluding Environmental Costs: Companies often ignore environmental expenses in market pricing, focusing primarily on profit maximization.
Environmental Worldviews
- Planetary Management: Advocates for human-centered management of Earth for indefinite benefit.
- Stewardship: Focuses on responsible management of resources with an aim to discourage environmental harm.
- Environmental Wisdom: Emphasizes human dependence on nature and the importance of preserving ecosystems for all species.
Characteristics of an Environmentally Sustainable Society
- Greater reliance on renewable energy sources.
- Protection and preservation of biodiversity.
- Reduction of waste and pollution production.
Conclusion
- The chapter concludes with emphasis on the interconnectedness of the discussed principles, the necessity of sustainable practices, and continued education on environmental impacts.
