The cities of Edmonton and Calgary are relatively far north and at high elevation. Which of the following best explains the data presented in their ecological footprints?

Colder average temperatures and longer nights in Edmonton and Calgary lead to high energy usage to heat and light homes.

After reviewing personal footprint data, Student 5 decides to take action to lower his or her overall footprint by reducing money spent on shoes and clothing. Land use in which of the following categories will be most affected by this change?

Goods and services

Which of the following statements is best supported by the data shown in the table?

Which of the following would be the best way to mitigate deforestation?

Grow more diverse timber products to increase economic value in an area

The chart above compares the daily water use per person to the price of water in selected countries. Which of the following conclusions can be correctly drawn using only the data in the chart?

Increased water use is generally correlated with lower water prices

Which of the following best illustrates a mitigation approach to climate change?

Increasing the proportion of commercial energy that is produced by wind farms

Which of the following actions would be most likely to increase the protection of ecological systems in national forests?

Mandate that the government sale of logging rights in national forests be at fair market value

Assume that the rainwater from one of the green roofs ran off directly into a nearby lake. Water quality results from which of the following parameters show that the green roof would likely improve water quality in the lake?

Nitrate

Which of the following is likely to minimize soil erosion?

No-till agriculture

Based on the data in the graph, which of the following Canadian cities had the lowest average per capita ecological footprint?

Ottawa

Which of the following represents a correct pairing of an agricultural practice with its environmental consequence?

Paddy rice cultivation and methane emissions

Which of the following is the best example of an economic incentive that could be used to improve environmental quality and reduce resource waste?

Providing tax breaks for companies that use recycled materials

Coal was surface mined from five sites, labeled 1 through 5, that had originally been covered by forest. Each site was planted with a mix of tree seedlings to reclaim the area to forest. Grass was also seeded over each site to prevent initial erosion and to provide forage. Ten years after planting, information was collected at the five sites and is given in the table below. Select the letter of the row that indicates the site with the most successful forest reclamation.

Row E

Which of the following best achieves the goal of providing wood products for humans while preserving biodiversity?

Selective cutting of large areas of old-growth forest

Which of the following problems is best addressed with contour plowing?

Soil erosion

Which of the following is a limitation of using only the data in the table to complete an ecological footprint analysis of the different students?

The footprint is a static analysis and does not include all environmental impacts of an individual.

Which of the following hypotheses is best supported by the trends shown in this graph?

The number of acres burned and the number of wildfires have decreased since 1930 because of more large-scale fire suppression interventions such as prescribed burns.

Which of the following is true of farm-raised salmon?

They are often infected with parasites and sea lice

The data in the table show mean concentrations (mg/L) of pollutants in rainwater leaving either green or conventional roofs. Which of the following data would be needed to calculate the total amount of a pollutant leaving the roof during and following a rainstorm?

Total volume of rainfall

Which of the following practices is consistent with the production of organic crops according to the United States Department of Agriculture?

Using chemicals known as pheromones to disrupt insect mating cycles

Which of the following is the best example of gray water?

Water that has been used for bathing and for washing clothes

Sustainable use of forests in the United States would likely be encouraged by

cutting small groups of medium- and large- sized trees in uneven-aged forests

Salmon farming threatens the health of wild salmon stocks primarily because

farmed salmon can spread parasites and disease to wild salmon

It has recently been estimated that the growth in world population has slowed in the past decade. Despite this trend, environmentalists remain concerned about the environmental impact of world population, principally because

the standard of living is increasing in many developing countries, leading to an increased per capita use of natural resources
