5. Highlights of Chapter 1 & 2
“Environmental Science and Sustainability”
-Concept of sustainability is central to the study of ES
-Population increase and natural resources
-Carrying Capacity
-Ecological Foot Print & IPAT
7. Ecological Foot Print
• The Ecological Footprint is a
resource accounting tool that
measures how much biologically
productive land and sea is used
by a given population or activity,
and compares this to how much
land and sea is available.
• The Ecological Footprint
measures the sum of these
areas, wherever they physically
occur on the planet.
8. What Would You Do?
Largest harmful effects:
- Food production and consumption
- Transportation
- Home energy use
- Overall resource use
Ideas for reduction in impact
- Food Production and Consumption
- Reducing meat consumption
- Buying or growing organic food
- Buying locally grown food
- Transportation - Driving energy-efficient vehicles
- Reducing car use
9. The IPAT Model
Impacts of different countries on environment
Three major factors considered:
- Population size (P),
- Affluence (A) or resource consumption per person
- Effects of technologies (T) (destructive or beneficial)
Impact (I) = Population (P) x Affluence (A) x Technology (T)
10. Presentation 1-2
• Overview: Choose two categories of natural resources (i.e., plants, animals, soil, minerals,
air, water, or energy sources).
• Then conduct your own research of primary literature (peer-reviewed work from
sources, especially discipline-specific journals) and, in a short overview presentation:
• 1. Define the two categories of natural resources
• 2. Compare and contrast their use (historical, present, and future potential)
• 3. Discuss how the two categories are interrelated
• 4. List your resources, with a minimum of two sources within your work, using APA in-
text format as well an APA-formatted reference slide at the end of the presentation
•
