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?

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

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= years

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:

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

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.

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

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.
