D 33) One might begin with a focus on the ecosystem services that regulate climate (solar energy budget), the flow of water through ecosystems (water cycle), or the absorption of pollutants (microbial decomposition and the essential recycling of matter). One could also describe the basic ecosystem processes such as any of the nutrient cycles (N cycle, which provides the critical N-compounds to plants that humans consume in order to build their essential N-containing compounds of DNA/RNA, enzymes, and proteins). The carbon cycle, moving O2 and CO2 through the ecosystem via the processes of photosynthesis and cellular respiration could also be described.

34) To be sustainable, actions must conform to the laws of mass and energy conservation. This is, something cannot be created from nothing, and everything goes somewhere. In order to manage a municipal water supply sustainably, one must understand the rate of renewal of the water source (is the source a mountain snowfield, constantly renewed, or is the source a more finite groundwater aquifer?). Secondly, one must have the ability and take the initiative to manage the rate of use of this water supply, based on changes in the area's population growth, also factoring in any new demands for this water supply with time (new land uses evolving, such as increased levels of agriculture).

B, II. C, III. D, IV. E, V. A 35) Individuals are often left to make their own decisions about how much they drive, how much energy they use, how much waste they generate, how much water is consumed. These things are hard to regulate from a governmental standpoint and are often regulated differently in each state and within each municipality. What is good for the government (a decrease in fossil fuel imports) is often not viewed as a positive for the individual (if it translates into less individual automobile use). Regarding a second issue, uncertainty and when to take definitive action on an environmental problem are debated for almost every environmental issue, especially early on. The precautionary principle approach says that when there is reasonable evidence that an action or policy may place human health or the environment at risk, precautionary measures should be taken, even if initial evidence seems inconclusive. This approach encapsulates the environmental debate over the global climate change issue, where energy companies might resist implementing controls over fossil fuel use, even though environmental change continues.

Answer Key Testname: CHAPTER 02_2E

36) The three main ethical approaches used to determine environmental value are anthropocentric, biocentric, and ecocentric views. Anthropocentric ethics assigns intrinsic value only to humans and defines right actions only in terms of positive outcomes for humans. The conservationist view of environmental management is an example of this human-centered approach. Biocentric ethics takes into consideration the value of other living things and values them equally with humans. This biocentric ethic is often articulated by those in the animal rights movement. Ecocentric ethics places value on communities of organisms and ecosystems, and is the most expansive and "big picture" approach to determining environmental value.

37) Ecological value can be measured by looking at ecological services provided by ecosystems and measuring the possible loss of services as a result of human impacts. Often these costs do not come into play until long after the ecosystem has been compromised or lost, and the services or actions that were supported by that ecosystem are now missing. For example, the ecological costs of the degradation of a forest are often not realized until reforestation of that land is required (because of extensive soil erosion, flooding, or siltation damage downstream) and undertaken.

38) GDP is the total value of goods and services produced by the citizens of a country divided by its population size. It is a measure of a country's economic standing and is used by governments and international organizations for assigning financial aid and making loans to nations. Because some actions may increase a country's GDP but reduce its human and natural resources (overharvesting forests or fisheries), economists have more recently suggested an alternative measure of natural wealth, the genuine progress indicator (GPI). GPI is the GDP plus or minus the economic value of enhancements or degradations to the environment. For example, actions such as forest destruction would decrease a country's GPI, while implementing waste management protocols would improve sustainability and increase a country's GPI.

When water is boiling the source of conduction is the gas or electricity on the stove, it provides the heat that will help to allow the molecules of water to boil.

Convection happens as the warm regions in the water become less dense and begin to rise, causing the boiling to begin. Radiation releases electromagnetic energy that is felt from the heat source and latent heat transfer occurs as the water evaporates as it boils, giving of steam that we might see.

41) The presence of water is often cited as the first critical factor, as all life we are familiar with requires water to live. The presence of water in a liquid state, especially in Earth's vast oceans, plays a central role in maintaining temperatures that support life, as these large liquid reservoirs help to moderate any extreme temperature fluctuations. Water vapor in the atmosphere also influences the extent of evaporation and precipitation, allowing water to cycle across the planet's surface.

A second critical factor is our unique distance from the sun (93 million miles). At this distance, the sun's energy and resulting temperature are not extreme, allowing organic compounds to form and life to flourish. A third critical factor was the evolution of photosynthetic organisms, which ultimately decreased the original concentrations of carbon dioxide and increased oxygen concentrations in the atmosphere, allowing a great diversity of life to evolve over the past 3.8 billion years. A fourth unique factor is the magnetic field arising from convection currents in the Earth's core and the Earth's rotation. This magnetic field deflects the lethal ionizing radiation from solar winds, to which other planets in our solar system are regularly subjected.

40) How would Darwin explain the origin of over a dozen different species of finches on the Galapagos Islands, when it was thought that only one species was the original parent species for all?

41) Population growth rates of various key species are important to understand, as large growth rates of any one species can easily affect the natural resources within an ecosystem. Assume that a population of 200 exotic parrots (all of the same species) accidentally escaped from a Miami zoo during a recent hurricane. After intense efforts, 215 are recaptured one year later. Calculate the population growth rate of this parrot species, and based on this growth rate, explain how long it would have taken for this population to double in size, if they had not been recaptured.

B, II. C, III. D, IV. E, V. A 40) At the heart of Darwin's explanation is his theory of natural selection, which states that within any species there is a natural variation for any given trait (in this case, beak size and shape). Once the parent species began to populate the various islands in the Galapagos, there were different selective forces at work on the finches because each island had slightly different physical parameters (for example, different temperatures and precipitation resulting in different vegetation). In the process of natural selection, individuals in a population that are most fit for that particular condition survive and leave more offspring, causing their adaptations to become more common in the population. Therefore, on the more desert/dry islands where smaller seeds were prevalent, finches that had smaller beaks were better suited and flourished. After several generations, the population on this island became mostly small-beaked finches. On one island, a species of finch actually evolved to use small sticks or cactus spines to prod insects from crevices and holes in trees, as there were very few seeds on this island.

C, II. D, III. A, IV. E, V. B 38) Pearl and Gould's model was based on the very limited data available in the 1930s. This was a time of widespread economic depression, and demographers assumed that worldwide poverty would continue, decreasing birth rates and increasing death rates. Their model argued for a slowing global population growth and estimated the world carrying capacity at 2.6 billion. However, following World War II, high birth rates and declining death rates were experienced for the next several decades, and Meadows and Meadows predicted a world population surpassing 7.4 billion by the year 2000, and 15 billion people by 2050. Their model was based on the assumption that the birth rates and death rates of the 1960s would continue. The UN prediction is somewhere between these two estimates, predicting an ever-decreasing population growth rate, as people in many developing countries begin having children later in life and fewer children. The United Nations forecasts a world population reaching approximately 9.3 billion by the year 2050.

39) Total fertility rate refers to the hypothetical number of children that a woman would have if she survived her entire reproductive lifetime. In Italy, the TFR is very close to the actual average because medical care is good and most women survive through menopause (their reproductive lifetime). In Ivory Coast, the TFR is probably greater than the actual average for women because mortality among women is high during their reproductive lifetime. TFR will likely decrease in both countries in the future, especially in developing countries where women's education and opportunities are increasing.

B, II. C, III. E, IV. A, V. D 41) Primary succession will result where a major disturbance has removed virtually all life, such as occurs with a retreating glacier from bare rock. Within several years, pioneer species such as lichens and mosses are able to colonize the rock surface, since these species are easily dispersed and able to tolerate the harsh conditions of this initial environment. These pioneer species will release small amounts of organic matter as they grow and die, modifying the rock surface, making it more favorable for other more complex species. Herbaceous plants and small shrubs begin to replace the original lichens and mosses, out-competing them. These new species, too, modify the environment, and are likewise replaced by other species such as woody plants and trees. Eventually, species become established which create environments that favor their own survival, and are adapted to the specific temperature and rainfall in their region. These species are known as the climax community and will likely be maintained until a major disturbance (i.e. fire or flood) alters the community, possibly to an earlier stage of succession.

42) Hutchinson suggested that each species has a fundamental niche, a range of environmental conditions (such as its requirement for temperature, food, and water), over which the species might possibly exist. Hutchinson noted that few species actually grow and reproduce in all parts of their theoretical range. Rather, each species usually exists only where they are able to compete effectively against other species: its realized niche. In the 1930s, the biologist G. F. Gause studied interspecific competition, ultimately postulating the competitive exclusion principle: when two species directly compete for essential resources, one species will eventually displace the other. In other words, Hutchinson explained that when the fundamental niche of two species significantly overlaps, these potential competitors are able to coexist because they divide up the fundamental niche, as no two species can occupy the same realized niche.

43) Photosynthesis and cellular respiration are the key processes involved in carbon's flux between the biosphere and the atmosphere. Normally carbon (C) contributes only a miniscule amount (0.032%) to the total mass of the lithosphere and atmosphere. During photosynthesis, CO2 is removed from the atmosphere by green plants, algae, and cyanobacteria, where it enters into a series of chemical reactions using light energy to add hydrogen ions and electrons, finally producing energy-rich carbohydrates. All organisms (photosynthetic as well as non-photosynthetic) access this energy through the process of cellular respiration, during which the carbohydrate is broken down, releasing CO2 back to the atmosphere. Deforestation and the burning of fossil fuels have greatly altered this dynamic that has existed between photosynthesis and cellular respiration. Scientists estimate that today, humans harvest approximately 32-40% of global NPP, having replaced natural ecosystems with farmland, cities, and suburbs. This has significantly diminished the amount of carbon stored in Earth's terrestrial ecosystems. For example, when a tropical forest is cleared and converted to pasture, a great amount of CO2 is released into the atmosphere. The burning of fossil fuels has also had a profound effect on Earth's carbon cycle. Between human land use and the burning of fossil fuels, human activities are raising the concentration of CO2 in the atmosphere by about 1% per year.

41) One environmental consequence of tropical rain forest destruction includes potential extinction of species. Much of the high species diversity in tropical rain forests is a consequence of evolution that has produced very specialized ecological niches. Many of these specialized species thrive within very restricted geographic ranges, making them extremely vulnerable to permanent elimination. Since many of these species have not been identified/studied, we are possibly eliminating species helpful to medicine and/or potential food sources. A second environmental consequence is the elimination of the natural nutrient cycling and productivity, which this great diversity of tropical forest plants represents. When forests are removed, the thin nutrient-poor tropical soils are exposed to the high levels of rainfall, and erosion results. The croplands that often replace the forests are able to grow food for only a short period of time, and when abandoned, results in even further soil erosion. A third consequence of tropical forest destruction is the elimination of their potential to take up and store carbon (in the form of CO2 during photosynthesis). This last concern is of particular issue for climate change, as deforestation is contributing to the increase in the greenhouse gas, CO2, in Earth's atmosphere. Increases in atmospheric CO2 have been directly linked with global temperature increases.

42) Temperature and precipitation are the two factors that determine the distribution of biomes. As average precipitation and temperature increase, the growing season is often longer, and with more water, photosynthetic rates increase, and vegetation becomes more lush and varied. For example, in the desert, with very little rainfall, the growing season is short, sometimes lasting less than a month. The plants that do thrive have evolved specialized adaptations to conserve water (reduced leaf surfaces, thorns/spines rather than leaves, and waxy leaf surfaces). Animal species have also evolved water conserving behaviors (nocturnal activity rather than diurnal feeding behavior and hibernation during the time of year with the highest temperatures). Many desert rodents also use water so efficiently that they are able to survive on the water generated from their food alone.

38) The Wilderness Act of 1964 and the Endangered Species Act of 1973 are two pieces of legislation designed specifically to preserve biodiversity. The Wilderness Act created a category of federal lands in which "the Earth and its community of life are untrammeled by man." This act prohibits logging, mining, and limits new road construction in these areas.

The current wilderness system is extremely important to the conservation of biodiversity. In fact, these lands form the core habitat of over 40% of the species that are listed as threatened or endangered in the United States. The Endangered Species Act was intended "to provide a means whereby the ecosystems upon which endangered and threatened species depend may be conserved, and to provide a program for the conservation of such species." This act prohibits the taking (no capturing, hunting, collection, or harassing) of any threatened or endangered species, regardless of land ownership. The ESA has played a significant role in slowing or halting declines in populations of many species (for example, bald eagle); however, its major criticism by environmentalists is that no action to conserve or restore habitat is actually mandated until a species is listed as threatened or endangered. Often times, this may be too late.

1)

Read the scenario and answer the accompanying questions.

The trapping of heat in the lower atmosphere (the troposphere), referred to as the greenhouse effect, is a natural process that helps regulate the temperature of our planet, allowing for life on Earth to exist and flourish. Nitrogen and oxygen molecules make up 99% of Earth's atmosphere, with water and carbon dioxide accounting for less than 0.5%. This natural greenhouse effect is the result of heat absorption by H2O and CO2 molecules in the lower atmosphere, and re-radiation of this trapped heat back to Earth's surface. Without the natural greenhouse effect, Earth's temperature would be 0°F instead of its present 57°F. The question for some is whether human activities are causing an increase of the greenhouse effect, and thus global climate change. Scientific data collected in the past 50 years indicates that the concentration of greenhouse gases in the atmosphere has been increasing.

They use mathematical equations to simulate the physical processes of absorption and reflection of sunlight by the atmosphere, the heating of the land and ocean, the circulation of heat from the equator to the poles, and when relevant, changes in the global ocean current patterns.

Scientists vary the global circulation models to simulate different scenarios. The scenarios differ in the assumptions about economic growth, fossil fuel consumption and use, government policies that affect energy use and human actions that increase greenhouse gas emissions. All these factors analyzed together produce different climate interactions, producing different climate change forecasts.

42) Regulations currently in place involve the U.S. government regulations for automobile mileage, known as the CAFÉ standards. The current CAFÉ standard for automobiles is 27.5 mpg. Since these standards are aimed at reducing fuel use, it has had a significant effect on CO2e emissions. European Union countries are regulating a diminishing dependence on fossil fuels, with an increasing proportion coming from renewable sources.

Economic incentives have been demonstrated by the current European Union cap-and-trade policy regulating greenhouse gas emissions from electric utilities. In this approach, after the regulatory cap has been determined for each electric utility, the utility manager may choose to reduce their emissions to meet this standard, or alternatively, they may purchase credits from other utilities whose CO2 emissions are below the cap. Gasoline taxes being employed by most industrial countries are another example of an economic incentive approach to reduce greenhouse gas emissions.

43) The expansion of water (in this case ocean water) as it warms is an important factor. Surface ocean waters have warmed as much a 0.9°F during the past 50 years. Also, the warming of the atmosphere has led to the melting of continental ice sheets and alpine glaciers, both of which increase the amount of water in ocean basins, causing sea level to rise. The melting of Arctic ice does not cause sea level to rise, as this ice is already floating on the surface of ocean water (just as an ice cube melting in a glass of water will not increase the volume of water in the glass).

44) (1) Atmospheric CO2 has been measured for time-frames going back 500,000 years by analyzing bubbles of air trapped in Antarctic ice cores. It has been found that CO2 concentrations were low during cold glacial period and high during warm interglacial periods; however, overall CO2 levels remained below 300 ppm throughout this time, until the Industrial Revolution, when CO2 began to increase to its current level of 388 ppm.

(2) Temperature measurements have been estimated by examining deep-sea sediment cores and measuring the relative amounts of hydrogen and oxygen isotopes in these cores. The same isotope ratios are reflected in the fossilized bodies (shells) of organisms found in these sediments. Using established relationships between isotope ratios and water temperature, temperature changes over a 300,000 period have been able to be determined.

43) Acid deposition is a secondary pollutant, formed in the atmosphere when sulfur and nitrogen oxides dissolve in water to produce sulfuric acid and nitric acid. Acid deposition can affect both aquatic and terrestrial ecosystems, in addition to human-made structures.

Aquatic ecosystems: Acid rainfall can dissolve aluminum and other toxic metals from soil. High levels of aluminum clog the gills of fish and also inhibit development of their skeletons.

Terrestrial ecosystems: Forests are negatively impacted by acid deposition when acidic rainwater leaches nutrients and minerals necessary for plant growth from the soils.

Human-made structures: Dry acid deposition is damaging to stone structures, gradually eroding buildings and historic architecture.

44) In 1976 the EPA began regulating lead emitted from automobiles, particularly after it was found to deactivate the catalysts in automobile catalytic converters. All automobiles manufactured after 1975 had to have a catalytic converter installed in order to help reduce the emissions of carbon monoxide, hydrocarbons, and nitrogen oxides. Since 1980, the use of leaded gasoline has now been banned in most countries, and global emissions of lead have decreased by 90% since 1970.

47) Since approximately 70% of the water that humans use goes to irrigate agricultural crops, improved technologies that can reduce evaporation and runoff from agricultural lands are essential. Drip irrigation, a process of delivering water to the roots of individual plants through a network of perforated tubes at the soil surface, has made a significant impact in reducing evaporation and runoff. A second strategy might be to reuse municipal waste water, recycling it to irrigate crops and/or for landscape watering. An essential consideration is to ensure that this wastewater is not contaminated with industrial by-products (heavy metals) if it is to be reused for human agriculture. Since wastewater is naturally high in nitrogen and other nutrients, using it to irrigate crops reduces the need for additional fertilizers. A third strategy is simple and focused personal water conservation approaches. Reducing shower time, using a low-flow shower head, and for home yards, using native plants that are adapted to the region where one lives, rather than exotic grasses that require large amounts of water in order to thrive.

48) Point source pollution can be defined as pollution that comes from a specific location, often indicated by an actual outflow pipe entering a body of water. Most point sources are industrial facilities and sewage treatment facilities. The 1972 Clean Water Act requires the EPA to regulate the discharge of pollutants into waterways. Non-point sources of water pollution include fertilizer-enriched runoff from farms and golf courses. Since its original passage, the Clean Water Act has been modified/amended in recent years to accommodate new knowledge, especially as it has related to the significance and impact of non-point water pollution. There is now specific language in the CWA, requiring management and minimization of non-point sources of water pollution.

44) Integrated pest management is the effective combination of chemical, biological, and cultural means to manage pests.

It is not the goal of IPM to completely eradicate pests, but the focus is to keep pest populations low enough to minimize crop loss. This approach requires extensive knowledge of pest life cycles and the interaction of pests with other organisms in the ecosystem. Less exposure of chemicals to the environment is a major IPM strategy. Using crop rotation, natural enemies, tilling of the soil to control weed growth, biological controls (pheromones), as well as using chemicals that have low impact on humans and other pests are some of the varied strategies used by IPM. Historically, farmers have used various measures to control insect pests. However, in the mid-20th century, powerful chemical pesticides including DDT and other broad-spectrum pesticides were used almost exclusively to control pests.

These pesticides have been found to disturb agroecosystems by killing helpful insects (pollinators as well as pest predators) as well as the harmful ones. Before the use of DDT, farmers had little appreciation for the role played by the natural predators of insect pests or the long-term persistence of these nondegrading chemicals in the environment.

This began to slowly change with the publication of Rachel Carson's Silent Spring, and the subsequent 1972 ban of DDT use in the United States. Use of chemical pesticides continues; however, the knowledge and benefits of IPM and organic farming practices are increasing.

45) The major issues related to dealing with large numbers of domestic animals are focused on the great volume of animal wastes produced and the dramatic changes in land use required for raising these animals. When exposed to weather, animal wastes release inorganic nutrients such as nitrates, ammonia, and phosphates that can pollute surface waters and nearby streams. These excess nutrients often lead to eutrophication and depletion of dissolved oxygen in aquatic ecosystems, with the subsequent death of aquatic species. Also, methane gas is a by-product of the digestion of nearly all herbivores. Since methane is a powerful greenhouse gas, the Intergovernmental Panel on Climate Change has estimated that methane emissions from livestock is accounting for more than 5% of current global warming. A second important environmental effect of domestic livestock operations is the major changes in land use. In many developing countries, forests are being cleared to create pasture land, thereby resulting in subsequent herbivore overgrazing and soil erosion. Removal of forests also reduces watershed protection, threatens biodiversity, and contributes to increased climate change, in that photosynthetic potential is reduced when vegetation is removed.

E 36) Firstly, biologists estimate that forests contain over 75% of the world's biodiversity in the form of microbes, plants, and animals. In addition to its intrinsic value, this biodiversity provides humans with an array of foodstuffs, clothing, pharmaceuticals, and building materials. The world's forests also provide an immense array of ecosystem services, especially pertaining to the normal functioning of the hydrologic cycle and providing an extensive carbon storage potential in the face of global warming. The roots of trees absorb large amounts of water, which eventually evaporates from leaves into the atmosphere, recondensing as rain. When forests are removed over a large area, rainfall in that area often declines. The volume and flow rate of rainfall runoff is also dramatically reduced by the presence of plants and leaf litter. Finally, forests store large amounts of carbon that they take in during the process of photosynthesis, storing this carbon in the form of carbohydrates in their tissues. Deforestation reduces total global forest carbon storage each year, and it is estimated that this CO2 increase accounts for about 15-20% of the anthropogenic carbon emissions that are currently contributing to global climate change.

Answer Key Testname: CHAPTER 13_2E

37) After a disturbance such as this windstorm (or fire or logging), a forest goes through four stages of succession. The forest first enters the establishment stage, when tree seedlings germinate on the newly cleared forest floor. Due to the loss of old-growth trees, these seedlings have abundant light and little competition for nutrients and water, and quickly grow into saplings. As these saplings grow, competition for light, nutrients, and water intensifies, leading to the next stage of succession. In the thinning stage, the largest trees continue to grow, but the total number of trees declines from several thousand per acre to several hundred, due to intense competition for resources. At the end of the thinning stage, large trees begin to die and leave gaps in the forest canopy. This leads to the transition stage, where seedlings can become established in these gaps. If there are no further disturbances, the forest will finally enter the old-growth stage, which is characterized by a mixture of large old trees and woody debris. Minnesota is a colder climate, so this recovery may take several hundred years.

Electrical current is the flow of electrons through a wire and is measured in amperes (amps). The voltage (volts) is a measure of the electric force required to keep electrons flowing through a wire. Power is the rate at which electricity does work, or provides energy, and is measured in watts (W). The current and voltage are related to electric power by the following equation: Power = volts × amps. Large amount of electric power is measured in kilowatts (kW). An electric bill reflects the total amount of electrical energy (expressed in kilowatt-hours, kWh), used by all electric appliances for the duration of the time (in hours) they were being used.

The use of electric or hybrid cars, and increasing the opportunities for buses and other mass transit options that are more energy efficient, are options moving us in the direction of a more sustainable transportation future. With higher gasoline prices and more stringent regulatory standards being instituted worldwide, incentives are being created for the production of more fuel-efficient vehicles and vehicles powered by alternative energy sources.

Electricity: The existing system of demand-driven generation and distribution of electricity is generally agreed to be wasteful and inefficient. Newer smart grid systems in which real-time pricing is employed (based on consumer high-demand times) and consumers are alerted to when "rush hour" demand periods are occurring, allows consumers to curtail their use and actually consider their electricity consumption in a more realistic manner. With smart grid systems, homes with solar panels would be able to sell their excess solar power back to the grid, or use batteries to store electricity purchased during slack hours for use at peak times.

39) In order to extract uranium ore from the ground, large quantities of rock must be removed and processed. This mining process disturbs large areas of land and leaves extensive mine tailings behind. These tailings are often acidified by rainfall, and have had severe negative impacts on nearby streams and lakes. Secondly, all nuclear power plants generate an extensive amount of heat from the normal fission process of the U235 atoms. In some cases, this heat is dissipated into nearby rivers, lakes, or ocean waters. Elevated temperatures in waters near nuclear power plants can alter the quality of the aquatic or marine habitats and diminish biodiversity. A third environmental impact has to do with the ultimate fate of the nuclear waste generated by nuclear power. To date, no permanent safe storage facility has been designated, and most spent nuclear fuel rods are currently stored on-site, at the over 100 U.S. plants. This spent nuclear fuel must be kept separate from the environment to avoid radioactive contamination of the environment. At present, there are no nuclear repositories in operation, and this continues to pose a potential environmental risk due to the long-term nature (over a million years) that safe storage requires.

B, II. C, III. E, IV. A, V. D 41) Using bioenergy offers a number of obvious environmental advantages over other forms of energy; however, it is the possible negative impacts associated with bioenergy attracting so much attention. Although the use of bioenergy is theoretically carbon neutral, in reality the use of many biofuels is not, as greenhouse gas emissions occur at many points in the biofuel production cycle. Significant quantities of fossil fuels are consumed in growing, shipping, and processing crops for biofuel. This specifically includes fossil fuels used by farm machinery, in the production of fertilizers and pesticides, and in pumping water for irrigation. A second concern regarding the use of corn and soybeans for biofuel has been the possible impact on the world economy, increasing the cost of food and even possibly causing food shortages. When land that normally is used to grow food is then transferred into fuel production, less land available for food production would be the issue. As world population continues to grow, this change in land use could have a significant effect.

42) The major environmental advantage for wind power is that it requires no fuel to generate electricity. Therefore, there is no need for mining, drilling, no radioactive wastes, no need for water in cooling towers, or any water pollution effects.

Because there is no fuel to burn, there is no release of air pollutants or greenhouse gases produced with wind turbine generation of electricity. On the negative side, some biologists acknowledge that there is a risk of bird and bat mortality associated with wind farms, but note that this impact is very small compared to the millions of birds that are killed annually by domestic house cats or by flying into cell phone towers.

Cities tend to be warmer than rural areas causing what is called an urban heat island. There are four reasons that might contribute to the heat island effect: 1. Cities have less vegetation than rural areas.

2. Rock, concrete, and asphalt often replace soil and naturally porous landscapes.

3. Buildings and other structures trap heat closer to the city.

4. Buildings, factories, and automobiles release pollutants and gaseous substances as well as generate waste heat.

Answer Key Testname: CHAPTER 16_2E

43) Efficient capture and use of energy and matter require that cities use and recycle the large input of energy and material resources in a more circular manner, rather than the linear approach that results in large outputs of waste. For example, requiring residents to put all wastes into one central collection area where recyclables can be separated from organic and other wastes. Recyclables could be sold to factories that use them for manufacturing of new products, and the combustible wastes could be burned, generating heat that could be used to generate electricity and hot water. The hot water can then be used for residential heating. Secondly, stormwater can be collected from green roofs, where it is purified for residential use. Finally, wastewater, including human waste is kept separate from stormwater and treated so that methane can be captured and used as a source of energy for the urban area. In this circular approach, very little waste results, as much of the original waste is recycled or captured in a usable form.

This can be accomplished by purchasing items in reusable containers, or if this is not possible for some items, then to choose items with as little packaging as possible.

Packaging waste (paper and plastic) accounts for a significant amount of waste entering the municipal waste stream.

Second, increasing the amount of recycling one participates in would be a significant action. Although the current rate of recycling in the United States is just over 30%, in Japan and many European countries it exceeds 50%. Finally, one could consider reusing some wastes, particularly paper and plastic bags used to carry purchased food and material goods. Never using another paper or plastic bag (using cloth, reusable bags instead) would be a significant action, especially if practiced by every U.S. citizen.

38) First, nuclear power plants primarily generate high-level radioactive wastes, mostly in the form of spent fuel rods.

With over 100 nuclear power plants in the United States, these sites are spread over vast regions of the country. They are currently the storage site for their own spent fuel rods: initially in wet storage (to dissipate the extreme heat) and finally in stainless steel casks for dry, longer-term storage. Because spent fuel rods still contain high levels of radioactive material, this waste must be kept away from groundwater, soil, humans, and the environment, even in the short term. Second, because the very long half-life of the radioactive isotopes making up the spent fuel, the safe storage and management requirements are much more comprehensive than on-site storage will allow. Permanent longterm storage continues to be an issue for the United States, as there has not been a central site licensed for this highlevel radioactive waste. Although Yucca Mountain, Nevada was proposed, the uncertainties presented by this site, and the nearby community concerns, have resulted in the government's failure to successfully identify a site that will meet all the criteria necessary for permanent storage.

C, II. D, III E, IV. A, V. B 38) The effect of toxic substances on humans varies considerably, depending on the factors of genetic makeup, age, health, and socioeconomic status. Firstly, one's genetic makeup plays an important role in susceptibility to chemicals. There is a growing body of evidence showing that humans vary in the ability of their DNA to be altered by toxic chemicals, thus equal toxicant exposures can result in quite a difference in susceptibility to cancer. Age particularly influences vulnerability because the young and developing, human nervous system undergoes enormous changes during the first decade of life, making children particularly vulnerable to neurotoxins. Finally, there is a growing body of evidence showing that socioeconomic status affects vulnerability to toxicants. Not only do poor people have more limited access to health care, they are also much more likely to live in environments that increase their risk of exposure. Living in older homes with lead paint, or living closer to industrial and waste facilities, are often considered normal living conditions for lower socioeconomic groups.

39) DDT is a synthetic chemical, developed in the mid-1940s as an insecticide to be used against malaria. This chemical has many of the critical characteristics that cause it to be particularly harmful to a wide array of warm-blooded organisms, including humans. Its persistence, transport in the environment, and uptake by many non-target organisms contribute significantly to its environmental health concerns. DDT is not easily broken down in the environment, and even its by-products are toxic. DDT's environmental persistence is estimated to vary between 30 and 100 years. Because it is sprayed over wide areas, it easily gets into water supplies and affects aquatic food webs.

Because it is taken up by insects and other small organisms found in lower trophic levels, its ability to bioaccumulate in higher organisms in the food chain is dependent on its fat solubility characteristic. That is, DDT is able to be stored in the tissues of living organisms without breaking down, and this characteristic leads to its biomagnification in the food web. Organisms that feed on other organisms whose tissues have stored DDT, are likely to store an even higher concentration. Some of the most well-documented environmental effects of DDT have been egg-shell thinning in birds of prey; however, cancer and developmental abnormalities have also been documented in amphibians and other higher vertebrates.

Putting a greater emphasis on any of these approaches would lessen the amount of oil needed to be refined for transportation purposes. Second, incorporating all of the external costs of producing oil should be factored into the cost of gasoline at the pump. The consumer cost of gasoline would then be much higher and might further encourage consumers to drive less and use more public transportation. Third, on a more comprehensive scale, one could advocate and promote local governments investigating the use of more renewable energy sources (wind turbines and Eco-Machines) for the running of town facilities such as wastewater and drinking water treatment plants.
