TAKE NOTES—The Powerpoint notes are not comprehensive by themselves. You must write what I say also. If you need a recorder that is fine.
Study,study,study…flash cards, reading your book, write out concepts. Each week and when an exam comes along.
Focus on the Powerpoint notes. You text covers a lot of material this helps you narrow down material.
Sustainability, is the ability of earth’s various systems to survive and adapt to environmental conditions indefinitely.
The steps to sustainability must be supported by sound science.
Natural capital: supported by solar capital Natural resources Natural services
E.g., nutrient cycling
Degradation of natural capital through human activities

Societies can become more environmentally sustainable through economic development dedicated to improving the quality of life for everyone without degrading the earth's life support systems.

Found at high enough levels in the environment to cause harm to organisms. Point source Nonpoint source
Problems with relying on cleanup: Often removes a pollutant from one part of the
environment to cause problems in another. Pollutants at harmful levels can cost too much to
reduce them to acceptable levels.
Pollutants can have three types of unwanted effects: Can disrupt / degrade life-support systems. Can damage health and property. Can create nuisances such as noise and
unpleasant smells, tastes, and sights.
Ecological footprint concept Biological capacity Ecological footprint Average ecological footprint of an individual in
a given country is called per capita ecological footprint.
The WWF estimates human’s global ecological footprint exceeded the earth’s biological capacity by how much? 25%
U.S consumption would only support 1.3 billion people.

Leading consumer of various foods and goods Wheat, rice, and meat Coal, fertilizers, steel, and cement
Second largest consumer of oil
Two-thirds of the most polluted cities are in China
Projections, by 2020 Largest consumer and producer of cars World’s leading economy in terms of GDP PPP
1-12
Companies do not pay the environmental cost of resource use
Goods and services do not include the harmful environmental costs
Companies receive tax breaks and subsidies
Economy may be stimulated but there may be a degradation of natural capital
Scientific research
Identify problem and multiple solutions
Consider human values
5–10% of the population can bring about major social change
Aldo Leopold: environmental ethics A leader of the conservation and
environmental movements of the 20th century Land ethic
Wrote: A Sand County Almanac
Estimate your own ecological footprint by visiting the website www.myfootprint.org/. What are 3 things you could do to reduce your ecological footprint?
(10 points)
Each person will turn in a paper with notes-Worth 15 points.
Be able to discuss your answers with other groups or the class. It is more important that you be able to discuss rather than writing everything out perfectly. If you are not participating I will mark your grade down.
It is important to express your opinion. This does not mean attacking each other. Ask the question am I talking too much or too little.
You of course can disagree with my opinions. Usually everyone has a different view and that is OK.
What’s the use of a house if you don’t have a decent planet to put it on?
