An environmental agency wants to evaluate the effectiveness of rain gardens in reducing the impact of urban runoff from an impervious parking lot and from the roof of the building. The parking lot is slightly sloped so the rainwater flows toward the gardens. The runoff from the roof is collected by various downspouts and directed toward the gardens. Scientists at the agency plan to monitor the effectiveness by measuring the water quality of the storm water as it moves through the gardens during and after storm events. Which of the following would be the best control in this experimental design? A Water samples collected from a faucet inside the building B Water samples collected from the roof or parking lot before they passed through the gardens C Soil samples collected from different rain gardens on the property D Soil samples collected from under the parking lots around the city

C This method delivers water to the field by pipes and water flows directly over the soil, but there is a large amount of runoff. D This method applies water directly to trenches dug in soil and is cost effective, but water is often lost to evaporation.

Which of the following is an assumption made by the author regarding the use of genetically modified crops? A Eventually, pests will become resistant to the BtBt gene, and pesticide use will increase in the near future. B The amount of arable land will remain relatively constant, and the growing human population will have enough food if more crops can be harvested from the same amount of land. C Farmers in more-developed countries will grow fewer genetically modified foods in the near future because they are not cost effective. D Current agricultural practices are effective enough to feed the global population, but improvements in technology will help crops such as cotton and tobacco.

Three common methods of beef production include using rangelands, pasture, and feedlots. The environmental impacts of these different methods for a variety of variables is compared in the graph below. The figure presents a vertical bar graph titled Relative Environmental Impacts of 3 Different Beef Production Systems. The horizontal indicates 4 categories of environmental impact: Greenhouse Gas; Energy Consumption; Erosion Rate; and Risk of Pesticide Contamination. The vertical axis is labeled Relative Value, and the numbers 0 through 350, in increments of 50, are indicated. There are 3 bars of data per environmental impact labeled Rangeland, Pasture, and Feedlot. The data are as follows. Note that all values are approximate. Greenhouse Gas. Rangeland, Relative Value, 135; Pasture, Relative Value, 125; Feedlot, Relative Value, 80. Energy Consumption. Rangeland, Relative Value, 45; Pasture, Relative Value, 120; Feedlot, Relative Value, 175. Erosion Rate. Rangeland, Relative Value, 75; Pasture, Relative Value, 95; Feedlot, Relative Value, 135. Risk of Pesticide Contamination. Rangeland, Relative Value, 35; Pasture, Relative Value, 190; Feedlot, Relative Value, 340. Which of the following claims is best supported by the data in the graph? A Raising beef on rangelands has the greatest environmental impact as a result of methane emissions and high levels of pesticide contamination. B Switching from raising beef on pastures to raising beef in feedlots decreases the total energy consumption and the rate of soil erosion as a result of an increase in vegetation in feedlots. C Feedlots have high levels of pesticide use and energy consumption as a result high demands for grain production. D Greenhouse gas emissions are equal across all beef production methods because all cattle produce methane gas and carbon dioxide.

C

Humans consume a variety of protein products, each with a different carbon footprint based on a variety of factors. Which of the following claims is best supported by the data in the graph? A Feedlot beef is the most sustainable protein because it has low requirements for fossil fuels, requires small pastures, and produces a large amount of protein for human consumption with low levels of pollution released. B Beans and soy products provide the least amount of protein for human consumption because they are plant-based foods. They require large amounts of land and have a high carbon footprint. C Seafood harvested from aquaculture has a larger carbon footprint than seafood harvested from fisheries. Aquaculture requires large amounts of fossil fuels and releases more greenhouse gases than fisheries do because the fish are more concentrated. D Grass-fed beef has the highest carbon-equivalent footprint because of land-use changes to create pasture land combined with contributions from transportation, processing, manure treatment, making fertilizers, and digestive fermentation processes.

Overexploitation factors: population growth, accessibility, ownership - how do these all apply?

population growth: an increased population leads to a higher demand for resources, causing overexploitation accessibility: having easier access to different resources (especially when they are cheap) can cause overexploitation of that resource ownership: increased ownership of businesses and land can lead to overexploitation of resources

tilling

preparation of soil by digging, stirring, and overturning -depletes nutrients, increases erosion, degradation, lost horizons, causes hardpans, increase co2

Prevention of Tragedy of the Commons

private ownership and government regulation

clear-cutting

Overfishing of stocks of fish species, like salmon and cod, in an effort to meet a growing global demand has become an international concern. A recent estimate indicates that the average annual consumption of fish globally in 2014 was about twice the consumption in 1960. Because of increased concerns about the impact of overfishing, fishery managers are looking for ways to protect wild populations while still satisfying global demand for food for human consumption. Aquaculture or fish farming can be used to increase the availability of species like salmon and shrimp for consumption. Although fish farming can have a number of negative environmental effects, it does offer a number of advantages. Which of the following is a valid reason for promoting the use of fish farms? A Fish production is constant, and fish farming reduces pressure on wild stocks. B Fish raised at fish farms are cheaper and have a better flavor than wild-caught fish. C Fish farming generates few, if any, pollutants that affect adjacent waterways. D Pesticides and antibiotics are rarely used at fish farms but are often used in wild-caught fish populations.

The green revolution has improved global agricultural output. Which of the following best describes the author's perspective on the beginning of the green revolution in the 1970s and 1980s? A The green revolution was successful because of selective breeding, which improved nutritional value and crop yield to increase food production. B The green revolution had minimal success because farmers were unable to provide grains to feed most of the global population until the 1990s, when synthetic fertilizers helped to improve crop yields. C The green revolution was successful because it decreased the demand for more farmland since genetically modified organisms increased the agricultural yield without increasing acreage dedicated to agriculture. D The green revolution was dangerous to the human population because the bacterium Bacillus thuringiensis was introduced into many species of corn and led to an outbreak of disease in humans.

The aim of reclamation is to restore the site to a condition similar to its condition before mining. (Removing buildings and other mining structures. Replacing overburden. Filling in mine shafts. Replanting vegetation.) You can measure its success by seeing if the land increases in biodiversity at all and see if any of the lands plants and animals return
