Study Notes
Chapter 1: Environmental Science and Sustainability
- Environmental Science and Sustainability: This chapter introduces the field of environmental science, focusing on the concept of sustainability.
- Chapter 1 Outline: The chapter is structured around key topics, including the definition of environment and ecosystems, sustainability, environmental justice, science, challenges to good science, and factors influencing environmental decisions.
- Chapter Objectives: To understand and describe how humans impact the environment; summarize the scientific method; explain various methods of observation and testing; and recognize the role of values in responding to environmental problems.
1.1 What is the Environment, and What is an Ecosystem?
- Environment: A collection of systems encompassing all living and nonliving things on Earth essential for sustaining life.
- System: A set of interacting components that generate predictable patterns over time, like a household. This principle of emergent properties highlights the combined effect being greater than simply summing the parts.
- Ecosystem: A natural system comprised of interacting living and nonliving elements, such as plants, animals, soil, water, and minerals. Coral reefs are examples of ecosystems. The prefix "eco" derives from the Greek word "oikos" meaning household.
- Ecosystem Services: The myriad of benefits humans receive from natural ecosystems, such as clean air and water, and food. Forests provide ecosystem services, including providing oxygen, water, and energy (and breaking down waste).
1.2 What is Sustainability?
- Sustainability: Managing natural resources without diminishing Earth's capacity to provide them in the future. This approach seeks to meet the needs of the present without compromising the future.
- Managing Natural Resources: Using resources, like fish populations, responsibly in a manner that supports future generations.
- Indigenous Knowledge: Acknowledging traditional knowledge systems and their understanding of sustainability for guidance about protecting ecosystems, such as the native people's protection of Pacific salmon.
- Sustainable Practices: Examples include less-polluting energy sources (e.g., solar power) and managed harvesting of natural resources, such as fish.
1.3 What is Environmental Justice?
- Environmental Justice: A key part of sustainability, this examines the disproportionate negative impacts of environmental problems on marginalized communities.
- Goal: This approach seeks fairer distribution of environmental burdens and benefits for all populations.
1.4 What is Science?
- Science as Inquiry: A process of asking and answering questions about the natural world using evidence-based methods.
- Scientific Method: A systematic process involving observation, hypothesis formation, experimental testing, data evaluation, and potential revision of hypotheses.
- Controlled Experiments: Experiments comparing two situations. In manipulating one situation, you can observe how the specific change (manipulated variable) affects the result. A key aspect is the control, a situation that is not manipulated to serve as a benchmark for comparison.
1.5 What Are Challenges to Good Science?
- Evaluating Sources: Assessing the integrity of information sources is crucial.
- Fraud: Deceptively presenting inaccurate findings.
- Pseudoscience: Claims that lack scientific rigor. This differs from fraud, as it may not be intentionally deceitful but neglects the proper scientific method.
1.6 What Shapes Our Decisions on the Environment?
- Sustainability Considerations: Decisions extend beyond scientific understanding to include personal and societal values.
- Values in Decision-Making: Personal values guide our choices and preferences regarding the environment.
- Examples: Personal choices affecting environmental impact, for example, choosing if you will bike to school or ride in a car.
Trade-offs and Incentives
- Trade-offs: Weighing the pros and cons or benefits and costs of different behaviors or decisions.
- Cost-Benefit Analyses: Public agencies and businesses may use communication strategies and economic analysis to alter decisions based on cost and benefit considerations.
- Incentives: Positive and negative motivations that encourage or discourage certain behaviors. For example: free bus rides encourage campus transportation; expensive parking discourages car use.
Making Sense of Our Environmental Effects
- Ecological Footprints: Analyzing personal and national-level impact on the environment, estimating the resources consumed.
- Carbon Footprints: Measuring greenhouse gas emissions related to lifestyles. Analyzing and understanding individual, local, and global environmental impacts can help you understand your place within these larger systems.
- Units of Measurement: Global hectares (gha) provides a standard way to measure land use in support of individual or national lifestyles.
Ecological Resilience
- Ecosystem Recovery: Understanding how well systems recover from disturbances and maintain overall health is essential for sustainable ecosystems.
- Resistance and Recovery: Recognizing that resistance to change and swift recovery processes help ecosystems maintain overall health and functionality. Coastal cities are examples of ecosystems that show resilience after being subjected to disturbances.
Sustainable Development Goals
- UN Goals: The UN created 17 global sustainable development goals addressing environmental, economic, and social aspects of human impact. Specific indicators are used to measure progress over time. Example: Marine pollution levels can assess sustainability efforts.
Additional Points (from specific questions)
- Ecosystem Services Example: Wetlands naturally purify water (Question 1)
- Anthropocene Epoch: Marked by significant human impacts on Earth (Question 2).
- 3Es of Sustainable Development: Environment, economy, and equity (Question 3).
- Scientific Method: A formal process of inquiry (Question 5).
