Exam 1: Introducing Environmental Science and Sustainability
How do you determine if a resource is renewable or nonrenewable? Give examples of both. What affects both of their usage?
A nonrenewable resource (minerals: aluminum, tin, copper, and fossil fuels: coal, oil, natural gas) are present in limited supplies and are depleted by use. Natural processes do not replenish nonrenewable resources within a reasonable period on the human time scale. Some take millions of years to form. Usage is affected by: nation's population, how efficiently the resources are extracted and processed, how much of it is required or consumed by different groups.
A renewable resource (trees, fisheries, fertile agriculture soil, fresh water) is naturally replaced at a fairly rapid pace (on a scale of days to decades), and they can be used forever as long as they are not overexploited in the short term. In developing countries, forests, fisheries, and agricultural land are particularly important renewable resources because they provide food. Rapid population growth can cause the overexploitation of renewable resources. Renewable resources are potentially renewable because they must be used in a sustainable way (a manner that gives them time to replace or replenish themselves).
What is the environmental significance of the process of "consumption"?
A
I = P x A x T model can be used to calculate which of the following?
E
In order to estimate human impact on the environment we can:
To test a hypothesis about a given variable, experimental and control groups are tested in parallel. Which of the following best explains the dual experiments?
What are Eco-roofs? What are their environmental benefits? Why are new buildings the best locations for them?
The current global ecological footprint of each person is about 2.7 hectares. The Earth presently has 11.4 billion hectares of productive land and water. If we divide this usable area by the global human population of approximately 6 billion, this means:
A state agency has contacted you to do a scientific assessment of kudzu in a nature preserve in southern Georgia. They are concerned about the effects of the non-native invasive vine on a small rare plant that grows on the forest floor in the preserve, but which is found nowhere else in the state. Kudzu is only growing in the east side of the preserve because it hasn't yet had time to invade further. In order to assess the effects of kudzu on the rare plant, you set up the following experiment:
Site 1. On the east side of the park with the kudzu, you set up ten 1m x 1m plots on the forest floor. In each plot you count the number of individuals of the rare plant.
Site 2. On the west side of the park without the kudzu, you set up ten 1m x 1m plots of the forest floor. In each plot you count the number of individuals of the rare plant.
Which of the following represents the hypothesis that you are testing with this experiment?
Create an illustrated dictionary entry for the term, "nonrenewable resource". Define the term, provide an example, a synonym and an antonym, and draw an illustration that represents the term.
The discovery of the extent of the pollution problem in Lake Washington was based on:
Which of the following statements about nutrients is false?

In this experiment, Site 2 is your:
The ability to meet humanity's current needs without compromising the ability of future generations to meet their needs is termed:
Define environmental sustainability. Discuss three reasons why experts in environmental science think that the human population is not operating sustainably.
Planet Earth is remarkably suited for life. Make connections between external environmental factors and the Earth's living organisms. Include in your discussion the concepts of habitability, evolution and emergence of dominant species.
