  1. 9/4 Do Now! • Fill out the Vocabulary Term Sheet on Your Desk with the word of the day- Environment • Environment: All external conditions and factors, living and non-living, that affect any living organism

  2. Environmental Science is… • Interdisciplinary study that uses information from the physical and social sciences to learn how the earth works, how we interact with the earth, and how to deal with environmental problems.

  3. Do Now 9/8 Write the definition of Resources in your notes. (if you would like a blank vocab sheet you can find one in extra copies) Resources: Anything obtained from the environment to meet human needs and wants. It can also be applied to other species

  4. Exponential Growth: • Definition: A quantity that increases at a fixed percentage per unit of time • Human population increases at approximately 2% per year

  5. Worldometer • http://Current Human Population/ • 53% of the people in the world have a daily income of less than $2.00 • 1/6 people are desperately poor at less than $1.00/day • What does this mean for the earth’s resources?

  6. Natural Capital • Natural resources that keep us and other species alive and support our economies • Degrading natural capital Example: Cutting down a forest faster than it can regrow

  7. Environmental Problems • What keeps us alive? What is an environmentally sustainable society? • How fast is the human population growing? • What is the difference economic growth, economic development, and environmentally sustainable economic development?

  8. 9/9 Do Now • Copy the definition of ecology into your notes. • Ecology: Biological science that studies the relationships between living organisms and their environment.

  9. Economic Growth: • the increase in the capacity of a country to provide people with goods, and services

  10. Gross Domestic Product: • the annual market value of all goods and services produced by all firms and organizations, foreign and domestic, operating within a country.

  11. Economic Development • the improvement of human living standards by economic growth • Developed Countries: (Made up of approximately 1.2 billion people) • U.S., Canada, Japan, Australia, New Zealand, and Most European countries • Developing Countries: (Made up of approximately 5.4 billion people) • Africa, Asia, and Latin America

  12. Exponential Growth And the Rule of 70 • 70/percentage growth rate= doubling time in years • Example: If the human population grew at 1.43% this past year, how long would it take to double the human population? • 70/1.43= 48.95 years

  13. The rule of 70: • Since 1985, China’s economy has been growing at 9.5% a year. At this growth rate, how many years would it take china to double?

  14. Perpetual resources • a resource that is renewed continuously on a human time scale

  15. Renewable Resource • can be replenished fairly rapidly through natural processes as long as it is not used faster than it is replaced.

  16. Sustainable Yield: • the highest rate at which a renewable resource can be used indefinitely without reducing it’s available supply

  17. Common property (aka free-access resources) • individuals do not own these resources, and they are free or cost very little to use What are some examples of free access resources?

  18. Tragedy of the commons: • each user reasons. “If I do not use this resource someone else will. The little bit I use or produce will not matter.”

  19. How can we prevent the tragedy of the commons?

  20. 9/10 Do Now: • On a piece of scrap paper, write you name and answer the following question… • What is the tragedy of the commons? • Hand into the inbox when finished.

  21. Ecological footprint: • the amount of biologically productive land and water needed to supply an area with resources and to absorb the wastes and pollution produced by such resources

  22. Per capita ecological footprint: • the average ecological footprint of an individual in an area • What happens when a country exceeds its ecological capacity (aka biocapacity)?

  23. Ecological Credit Card • It is estimated that it will take the resources of 1.39 planet earths to indefinitely support or current production and consumption of renewable resources.

  24. How is the growth of the world’s ecological footprint related to exponential growth of the world’s population and economies? • What are three things you would do to reduce the global ecological footprint and your own individual foot print?

  25. Do Now 9/15 • Copy the definition of Environmentalism in your notes. • Environmentalism: Social movement dedicated to protecting the earth’s life support systems for us and other species.

  27. POPULATION GROWTH, ECONOMIC GROWTH, AND ECONOMIC DEVELOPMENT • Economic growth provides people with more goods and services. • Measured in gross domestic product (GDP) • Economic development uses economic growth to improve living standards. • The world’s countries economic status (developed vs. developing) are based on their degree of industrialization and GDP

  28. Percentage of World's 18 Population 82 0.1 Population Growth 1.5 85 Wealth and Income 15 88 Resource use 12 Pollution and waste 75 25 Developingcountries Developed countries Fig. 1-5, p. 11

  30. RESOURCES • Perpetual: On a human time scale are continuous. • Renewable:On a human time scale can be replenished rapidly (e.g. hours to several decades). • Nonrenewable: On a human time scale are in fixed supply.

  31. Nonrenewable Resources • Exist as fixed quantity • Becomes economically depleted. • Recycling and reusing extends supply • Recycling processes waste material into new material. • Reuse is using a resource over again in the same form. Figure 1-8

  32. Ecological footprint: • the amount of biologically productive land and water needed to supply an area with resources and to absorb the wastes and pollution produced by such resources

  33. Total Footprint (million hectares) and Share of Global Ecological Capacity (%) 2,810 (25%) United States 2,160 (19%) European Union 2,050 (18%) China 780 (7%) India Japan 540 (5%) Fig. 1-7a, p. 13

  34. Earth’s Ecological Capacity Number of Earths Humanity's Ecological Footprint Year Fig. 1-7c, p. 13

  35. Footprint Per Person (hectares per person) 9.7 United States 4.7 European Union 1.6 China 0.8 India 4.8 Japan Fig. 1-7b, p. 13

  36. Per capita ecological footprint: • the average ecological footprint of an individual in an area • What happens when a country exceeds its ecological capacity (aka biocapacity)?

  37. Ecological Credit Card • It is estimated that it will take the resources of 1.39 planet earths to indefinitely support or current production and consumption of renewable resources.

  38. POLLUTION • Pollutants are chemicals found at high enough levels in the environment to cause harm to organisms. • Point source • Nonpoint source Figure 1-9

  39. Pollutant Sources • Point source- single identifiable source • Ex. Smokestack of a coal burning industrial plant • Nonpoint source- larger, dispersed, difficult to identify • Ex. Pesticides sprayed into the air and carried by the wind

  40. Pollution Effects • Pollutants can have three types of unwanted effects: • 1.) Can disrupt / degrade life-support systems. • 2.) Can damage health and property. • 3.) Can create nuisances such as noise and unpleasant smells, tastes, and sights.

  41. The 2 Pollution Solutions • Pollution Prevention AKA Input pollution control • Pollution Cleanup or Output pollution control.

  42. Find an Article on Pollution • The article must demonstrate how pollution affects your life. • Based on the article you find, write minimum of ½ page explaining how pollution affects your life. • COMPLETE AS HOMEWORK IF NOT FINISHED IN CLASS • Due Wednesday 9/17
