Study Notes
Environmental Problems
- Environmental problems are difficult to solve due to multiple causes and consequences, differing stakeholder preferences, and potential solutions with trade-offs.
Environmental Literacy
- Environmental literacy is crucial for solving or preventing environmental problems by understanding how ecosystems function and the impact of human choices on the environment.
Wicked Problems: Climate Change
- Causes of climate change: burning fossil fuels, deforestation, methane from agriculture, and overconsumption by modern society.
- Consequences of climate change: sea level rise, habitat loss and species endangerment, and spread of tropical diseases.
Stakeholder Differences
- Different stakeholders have varying priorities: island dwellers, farmers, fossil fuel industry, and wildlife conservation groups.
Solutions with Trade-Offs
- Alternative energy sources: less pollution but costly.
- Irrigation: increases crop yields but can cause water shortages and soil problems.
- Reforestation projects: lessen CO2 in the atmosphere and increase habitats but may take land away from agriculture.
Environmental Science
- Draws on science and non-science disciplines to understand the natural world and our relationship to it.
- Includes the study of the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere.
Components of the Environment
- Atmospheric layer of gases, hydrosphere (water), cryosphere (ice and snow), lithosphere (upper mantle), and biosphere (region where life exists).
- Non-animate phenomena: weather patterns, pH of the soil.
Resources
- Components of the environment that we need or want, obtained from the environment.
- Anthropocentric view: values resources based on human interests, wants, and needs.
- Ecocentric/Biocentric view: values aspects of the environment simply because they exist.
Environmentalism and Stewardship
- Environmentalism: a social movement aiming to protect the natural world from human-caused changes.
- Environmental stewardship: protection of the natural environment through conservation and sustainable practices.
- Education is a crucial factor in promoting environmental stewardship.
