Chapter 1: The Environmental Challenge

1)Assessing the potential effects of different interventions to solve environmental problems is termed

2. An ecologist samples the level of suspended solids in the water of a stream that has been restored to reduce bank erosion. Which step of the problem-solving process is the ecologist using?
3. A better approach to dealing with environmental problems such as disposal of radioactive waste would place great emphasis on what?
4. How do ecology and environmental science differ from one another?
5. An environmental chemist is interested in testing the hypothesis that nitrate concentrations in water can impact the health of fish. To test this hypothesis, the scientist exposes a group of fish to differing levels of nitrate. The scientist also needs to test a control group. How would the scientist create a control group for this experiment?
6. A theory differs from a hypothesis in that the hypothesis is
7. What is a major limitation of science when trying to solve environmental problems?
8. Which of the following options would a forest manager consider to make timber harvest more sustainable over time?
9. Which action would you recommend to prevent additional acres of rangeland from becoming desertified?

10. Which of the following is inaccurate about our current society?
11. The manufacture of chemicals that were found to degrade ozone in the atmosphere was reduced by the Montreal Protocol. Still, the ozone hole has not managed to fully repair itself. Given what you know about sustainability, why do you think the ozone hole remains an issue?
12. Which economy is likely to have the largest ecological footprint?
13. In general, which type of country would have a higher ecological footprint, assuming they both have the same population size, a highly developing or a moderately developed one?
14. Which of the following is a major prediction of the IPAT model?
15. What would have to happen for us to achieve sustainability given the current trends in global population growth?
16. What variables would we need to know in order to calculate the environmental impact of CO2 emissions from cars in India?
17. How do social factors influence consumption of resources?
18. An ecologist checks the turbidity (amount of sediment floating in the water) in a stream to determine if a stream bank restoration project has been successful. The ecologist is performing which step in the problem solving process?
