Do you recommend any of the other mining methods described, such as in-place mining, biomining, ocean mining, or more? Why or why not do you think these methods should be explored?
I think in-place mining and biomining should be tested more thoroughly because they are naturally occurring bacteria used to remove desired metals from ores through wells bored into the deposits. It leaves the surrounding environment undisturbed and reduces the air pollution associated with the smelting of metal ores and reduces water pollution from releases of hazardous chemicals. Even though it's a slow process, I think it's totally worth it to explore.

Describe the U.S. General Mining Law of 1872. What problems existed with the law and what is being done to improve regulations?
It was designed to encourage mineral exploration and the mining of hard rock minerals-such as gold, solver, copper, and uranium-on public lands and to help develop the western territories. Under this law, a person or corporation can file a mining claim or assume legal ownership of parcels of land on essentially all U.S. public land except national parks and wilderness. Mining companies remove at least $4 billion worth of hard rock minerals per year from US lands and degrade the lands and leave behind a toxic mess. In 1992, the law was modified to require mining companies to post bonds to cover 100% of the estimated cleanup costs in case they go bankrupt but this would cost too much money for taxpayers. EPA and the government are working together to create to new rules guaranteeing that miners will pay all cleanup costs.

Current Energy Imbalance
"Earth's energy imbalance is the difference between the amount of solar energy absorbed by Earth and the amount of energy the planet radiates to space as heat. If the imbalance is positive, more energy coming in than going out, we can expect Earth to become warmer in the future — but cooler if the imbalance is negative. Earth's energy imbalance is thus the single most crucial measure of the status of Earth's climate and it defines expectations for future climate change."

Use of Large Dams Provides Benefits and Creates Problems
A dam is a structure built across a river to control its flow. Usually, dammed water creates an artificial lake, or reservoir, behind the dam (Figure 13-2). The main goals of a dam-and-reservoir system are to capture and store the surface runoff from a river's watershed, and release it as needed to control floods; to generate electricity (hydropower); and to supply freshwater for irrigation and for towns and cities. Reservoirs also provide recreational activities such as swimming, fishing, and boating. Large dams and reservoirs provide benefits but have drawbacks (Figure 13-17).

We Are Using Increasing Amounts of the World's Reliable Runoff
According to hydrologists (scientists who study water and its movements above, on, and below the earth's surface), two-thirds of the annual surface runoff of freshwater into rivers and streams is lost in seasonal floods and is not available for human use. The remaining one-third is reliable surface runoff, which we can generally count on as a source of freshwater from year to year. During the last century, the human population tripled, global water withdrawals increased sevenfold, and per capita withdrawals quadrupled. As a result, we now withdraw about 34% of the world's reliable runoff. This is a global average. In the arid American Southwest, up to 70% of the reliable runoff is withdrawn for human purposes, mostly for irrigation (Core Case Study and Case Study that follows). Some water experts project that because of a combination of population growth, rising rates of water use per person, longer dry periods, and failure to reduce unnecessary water losses, we may be withdrawing up to 90% of the reliable freshwater runoff by 2025.
Reducing Freshwater Losses Can Provide Many Benefits
According to water resource expert Mohamed El-Ashry of the World Resources Institute, about 66% of the freshwater used in the world and about 50% of the freshwater used in the United States is lost through evaporation, leaks, and inefficient use. El-Ashry estimates that it is economically and technically feasible to reduce such losses to 15%, thereby meeting most of the world's freshwater needs for the foreseeable future.

Groundwater Is Being Withdrawn Faster Than It Is Replenished in Some Areas
Aquifers provide drinking water for nearly half of the world's people. Most aquifers are renewable resources unless the groundwater they contain becomes contaminated or is removed faster than it is replenished. In the United States, aquifers supply almost all of the drinking water in rural areas, one-fifth of that in urban areas, and 37% of the country's irrigation water. Relying more on groundwater has advantages and disadvantages (Figure 13-11).
How are depletion times for resources calculated and why do experts get such different values from each other?
Calculates through analysis of amount of reserves and steps that can be taken to preserve them. Shortest depletion-time estimate assumes no recycling or reuse and no increase in reserves. A longer depletion-time estimate assumes that recycling will stretch existing reserves and that better mining technology, higher prices, or new discoveries will increase reserves. Longest estimate makes same assumptions, but also includes reuse and reduced consumption to further expand reserves. Experts get different values because they're using different assumptions about supplies and rates of use.

We Can Use Less Water to Remove Wastes
Currently, we use large amounts of freshwater clean enough to drink to flush away industrial, animal, and household wastes. According to the Food and Agriculture Organization of the United Nations (FAO), if current growth trends in population and water use continue, within 40 years, we will need the world's entire reliable flow of river water just to dilute and transport the wastes we produce each year.
We can convert salty ocean water to freshwater, but the cost is high, and the resulting salty brine must be disposed of without harming aquatic or terrestrial ecosystems.
Desalination is the process of removing dissolved salts from ocean water or from brackish (slightly salty) water in aquifers or lakes. It is another way to increase supplies of freshwater (Concept 13-5). The two most widely used methods for desalinating water are distillation and reverse osmosis. Distillation involves heating saltwater until it evaporates (leaving behind salts in solid form) and condenses as freshwater. Reverse osmosis (or microfiltration) uses high pressure to force saltwater through a membrane filter with pores small enough to remove the salt and other impurities.
Point source
Discharge pollutants at specific locations through drain pipes, ditches, or sewer lines into standing bodies of water.

What are some of the environmental impacts that result from mining? Explain.
Disturbed land, mine waste dumping, oil spills, and heat from the exploration and extraction in mining. Solid wastes, radioactive material, air, water, and soil pollution from processing (transportation, purification, manufacturing). Thermal water pollution, pollution of air, water, and soil, solid and radioactive wastes from use (transportation or transmission to individual user, eventual use, and discarding). Surface mining scars and disrupts land surface and destroys or degrades biodiversity when ricers are polluted with mining wastes and forests are cleared. Mining produces large amounts of wastes, which cause air, and water pollution and huge amounts of water used to process ore often contain pollutants such as sulfuric acid and arsenic and this runoff contaminates freshwater supplies and fish used for food. Also, toxic chemicals are released into the atmosphere.

Read the three case studies on pages 421-424 (biodiesel, ethanol, algae/bacteria). Which method do you believe is the most practical and successful for getting energy from natural sources? Explain specific reasons why your selection has advantages over the other two methods using examples from the studies.
I think using algae/bacteria would be best because it hardly impacts the environment; it could be done anywhere, and doesn't release emissions in the process. Other methods don't yield as much energy, they're costly to do, and they emit pollutants like NOx and smog (biodiesel) and CO2 (ethanol).

Water Transfers Can Be Inefficient and Environmentally Harmful
In some heavily populated dry areas of the world, governments have tried to solve water shortage problems by transferring water to the dry areas from water-rich areas. For example, northern China contains rapidly growing cities, including Beijing with 17.3 million people. These urban populations have helped to deplete underlying aquifers. According to the Chinese Academy of Sciences, two-thirds of China's 669 major cities have water shortages, more than 40% of its rivers are severely polluted, and about 300 million rural residents—a number almost equal to the size of the U.S. population—do not have access to safe drinking water. To help with this serious problem and to boost food production, the Chinese government is implementing its South-North Water Diversion Project to transfer 23 trillion liters (6 trillion gallons of water) per year from the Yangtze River in southern China to the thirsty north.
What are some of the environmental impacts that can result from coal ash? Explain.

Poor Farmers Conserve Water Using Low-Tech Methods
Many of the world's poor farmers use small-scale, low-cost traditional irrigation technologies that are far more sustainable than most large-scale irrigation systems. For example, millions of farmers in Bangladesh and other countries where water tables are high use human-powered treadle pumps to bring groundwater up to the earth's surface and into irrigation ditches (Figure 13-24). These wooden devices are inexpensive (about $25) and easy to build from local materials. One such pump developed by the nonprofit International Development Enterprises (IDE) uses 60-70% less water than a conventional gravity-flow system to irrigate the same amount of cropland.
We Can Reduce Flood Risks
Many scientists argue that we could improve flood control by relying less on engineered devices such as dams and levees and more on nature's systems such as wetlands and forests in watersheds. One engineering approach is the channelizing of streams, which does reduce upstream flooding. However, it also eliminates the aquatic habitats that lie along a meandering stream by taking the water from those systems and sending it in a faster flow straight down a channel. It also reduces groundwater recharge and often leads to downstream flooding. Similarly, levees or floodwalls along the banks of a river contain and speed up stream flow and can lead to flooding downstream. They also do not protect against unusually high and powerful floodwaters such as those that occurred in 1993 when two-thirds of the levees along the Mississippi River were damaged or destroyed. Similar flooding occurred along the Mississippi in 2011.

What is OPEC and what power does it hold politically and economically?
Organization of Petroleum Exporting Countries have about 60% of the world's proven crude oil reserves and thus are likely to control most of the world's oil supplies for many decades. Members are Algeria, Angola, Ecuador, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, and Venezuela. The OPEC produced about 39% of the world's oil in 2009.
Based on projections of how long the oil supply will last, do you believe any of the four options on page 375 need to be explored?
Out of the options: look for more oil, use less oil, waste less oil, or use other energy resources, the latter three are the most probable. Looking for more oil will deplete the land even more. However, using and wasting less oil will be good for the environment and for the amount of oil we have. Using other resources would be good if they were sustainable, safe, and had a high yield (not nuclear power).

Overpumping of Aquifers Can Have Harmful Effects
Overpumping of aquifers can contribute to limits on food production, rising food prices, and widening gaps between the rich and poor in some areas. As water tables drop, farmers must drill deeper wells, buy larger pumps, and use more electricity to run those pumps. Poor farmers cannot afford to do this and end up losing their land and working for richer farmers, or migrating to cities that are already crowded with poor people struggling to survive. Withdrawing large amounts of groundwater sometimes causes the sand and rock that is held in place by water pressure in aquifers to collapse. This can cause the land above the aquifer to subside or sink, a phenomenon known as land subsidence. Extreme, sudden subsidence is sometimes referred to as a sinkhole. Once an aquifer becomes compressed by subsidence, recharge is impossible. In addition, land subsidence can damage roadways, water and sewer lines, and building foundations. Since 1925, overpumping of an aquifer to irrigate crops in California's San Joaquin Valley has caused half of the valley's land to subside by more than 0.3 meter (1 foot) and, in one area, by more than 8.5 meters (28 feet) (Figure 13-15).

We Can Cut Freshwater Losses in Industries and Homes
Producers of chemicals, paper, oil, coal, primary metals, and processed foods consume almost 90% of the freshwater used by industries in the United States. Some of these industries recapture, purify, and recycle water to reduce their water use and water treatment costs. For example, more than 95% of the freshwater used to make steel can be recycled. Even so, most industrial processes could be redesigned to use much less freshwater. GREEN CAREER: water conservation specialist Flushing toilets with freshwater (most of it clean enough to drink) is the single largest use of domestic freshwater in the United States and accounts for about one-fourth of home water use. Since 1992, U.S. government standards have required that new toilets use no more than 6.1 liters (1.6 gallons) of freshwater per flush. Even at this rate, just two flushes of such a toilet require more than the daily amount of freshwater available for all uses to many of the world's poor living in arid regions (see chapter-opening photo).
What are at least two of the five solutions for building new nuclear power plants in the future? P. 393
Reactors must be built so that a runaway chain reaction is impossible Its entire fuel cycle must generate fewer greenhouse gas emissions than other energy alternatives
Nuclear power is the slowest growing form of energy and it was projected to make up the largest supply. What factors account for why nuclear power has been slow to grow?
Reactors wear out and retired faster than new ones are built, has a low net energy yield, funded greatly by taxpayers and subsidies, and there's no political or scientific consensus on how to safely store the resulting highly radioactive wastes for thousands of years. There are also concerns about the safety of nuclear reactors from radiation, melting, explosion, etc.

What are two ways in which industries can reduce their energy use?
Replace energy-wasting electric motors, which use ¼ of the electricity produced in the US and 65% of the electricity used in US industry. Most are inefficient and reducing them would save energy and reduce environmental impact of electric motor use. Recycling materials such as steel and other metals is another way to save energy and money. For example, producing steel from recycled scrap iron uses 75% less energy than producing steel from virgin iron ore and emits 40% less CO2. Switching ¾ of the world's steel production to such furnaces would cut energy use in the global steel industry by 40% and sharply reduce its CO2 emissions.
c
Respiratory illnesses in developing countries are most likely to be caused by... a. formaldehyde b. cigarette smoke c. particulate matter d. asbestos e. chloroform
What are current limitations that prevent renewable energy sources from making up more of the world's energy supply?
Since 1950, government tax breaks, subsidies, and funding for research and development for renewable energy resources have been much lower than those for fossil fuels and nuclear power. Although subsidies and tax breaks for fossil fuels have essentially been guaranteed for many decades, those for renewable energy have to be renewed by Congress every few years and this makes it risky for companies to invest in renewable energy. Prices we pay for nonrenewable fossil fuels and nuclear power don't include the harmful environmental and human health costs of producing and using them.
We Can Improve Efficiency in Irrigation
Since 1980, the amount of food that can be grown per drop of water has roughly doubled. And since the 1970s, the amount of water used per person in the United States has dropped by about 33%, after rising for decades. Most of these water savings have come from improvements to irrigation efficiency in the United States and other more-developed countries.
What happened at Chernobyl? What lasting impacts has it had on human health and the environment?
Site of the most serious nuclear power plant accident. On April 26, 1986, two simultaneous explosions in one of the four operating reactors in this nuclear power plants in Ukraine blew the roof off the building. The reactor burned for 10 days and a radioactive cloud spread over the whole world. By 2005, 56 people died prematurely from exposure to radiation released by the accident. The number of premature deaths ranges from 9,000 to 212,000. In parts of the Ukraine, some people can't drink the water or eat locally produced food. There are higher rates of thyroid cancer, leukemia, and immune system abnormalities in children exposed to the fallout.

Some Areas Get Too Much Water from Flooding
Some areas have too little freshwater, but others sometimes have too much because of natural flooding by streams, caused mostly by heavy rain or rapidly melting snow. A flood happens when freshwater in a stream overflows its normal channel and spills into the adjacent area, called the floodplain. People settle on floodplains to take advantage of their many assets, including fertile soil on flat land suitable for crops, ample freshwater for irrigation, and availability of nearby rivers for transportation and recreation. In efforts to reduce the threat of flooding on floodplains, rivers have been narrowed and straightened (or channelized), surrounded by protective dikes and levees (long mounds of earth along their banks), and dammed to create reservoirs that store and release water as needed (Figure 13-2). However, in the long run, such measures can lead to greatly increased flood damage when heavy snowmelt or prolonged rains overwhelm them.
Groundwater and Surface Water Are Critical Resources
Some precipitation infiltrates the ground and percolates downward through spaces in soil, gravel, and rock until an impenetrable layer of rock or clay stops it. The freshwater in these spaces is called groundwater—a key component of the earth's natural capital. The spaces in soil and rock close to the earth's surface hold little moisture. However, below a certain depth, in the zone of saturation, these spaces are completely filled with freshwater. The top of this groundwater zone is the water table. It falls in dry weather, or when we remove groundwater faster than nature can replenish it, and it rises in wet weather. Deeper down are geological layers called aquifers, underground caverns and porous layers of sand, gravel, or rock through which groundwater flows. Mostly because of gravity, groundwater normally moves from points of high elevation and pressure to points of lower elevation and pressure. Some caverns have rivers of groundwater flowing through them. However, the porous layers of sand, gravel, or rock in most aquifers are like large, elongated sponges through which groundwater seeps—typically moving only a meter or so (about 3 feet) per year and rarely more than 0.3 meter (1 foot) per day. Watertight layers of rock or clay below such aquifers keep the freshwater from escaping deeper into the earth.

Describe two other serious problems that nuclear power plants pose.

Describe the difference between surface and subsurface mining techniques. Which do you think has less of an impact to the surrounding ecosystems?
Surface mining extracts mineral deposits that lie in large horizontal beds close to the earth's surface. Subsurface mining removes deep deposits of minerals in which underground mineral resources are removed through tunnels and shafts. This method is used to remove coal and metal ores that are too deep to be extracted by surface mining. Subsurface mining has less of an impact on surrounding ecosystems because it disturbs less than 1/10 as much land as surface mining disturbs, and it usually produces less waste material.

How is tar sand and shale oil used to extract oil? Where is the largest supply of each found in the world?
Tar sand is used to extract oil by strip mining. The ecosystem (forests, wetlands, etc.) covering the ground is stropped away to expose the tar sand deposits. Then five story high electric power shovels dig up the tar sand and load it into trucks, which transport it to an upgrading plant. There the sand is mixed with hot water and steam to extract the bitumen and converted into a heavy crude oil for refining. The largest supply is found in Saudi Arabia with 20% of the world's oil reserves. Shale oil takes a lot of energy to extract and has a low net energy yield. It also takes a lot of water to produce shale oil (5 barrels water/1 barrel shale oil). Has a higher environmental impact and releases more CO2. About 72% of the world's reserves are buried deep in rock formations located primarily in government-owned lands in Wyoming, Colorado, and Utah (Green River formation and Bakken oil formation).

Most of the Earth's Freshwater Is Not Available to Us
The earth is often called the blue planet because of its abundance of water in all forms: liquid, solid (ice), and gas (water vapor). However, only a tiny fraction—about 0.024% of the planet's enormous water supply—is readily available to us as liquid freshwater, stored in accessible underground deposits and in lakes, rivers, and streams. The rest is in the salty oceans (about 96.5% of the earth's volume of liquid water), in frozen polar ice caps and glaciers (1.7%), and in underground aquifers (1.7%) (see Figure 25, Supplement 6). Fortunately, the world's freshwater supply is continually recycled, purified, and distributed in the earth's hydrologic cycle (see Figure 3-15). This irreplaceable water recycling and purification system works well, unless we alter it, overload it with pollutants, or withdraw freshwater from underground and surface water supplies faster than it can be replenished.

Describe why an energy source might have a high net energy yield or a low net energy yield. What actions are put in to place in order to account for low net energy yields?
The location and ease of access of an energy source helps determine the net energy yield. For example, most conventional oil has a high net energy ration because for many years, much of it has come form large concentrated deposits if light crude oil found not too deep underground or under the ocean floor in fairly shallow water. As these sources become depleted, oil producers have to use more energy and money to develop more dispersed and often smaller deposits that are found deeper underground or under the sea bottom. As this occurs, the net energy ratio of conventional oil declines. The actions put into place are that many governments subsidize the source that has a low net energy yield to make it available because it can't compete in the open market unless US gov't (taxpayers) provides it with large tax breaks/subsidies
Freshwater Shortages Will Grow
The main factors that cause water scarcity in any particular area are a dry climate, drought, too many people using a freshwater supply more quickly than it can be replenished, and inefficient use of freshwater. Figure 13-9 shows the current degree of scarcity stress—a measure based on a comparison of the amount of freshwater available with the amount used by humans—faced by each of the world's major river systems. Like the Colorado River (Core Case Study), major rivers including the Nile, Jordan, Yangtze, and Ganges are stressed so highly that their flows regularly dwindle to almost nothing in some locations.

What are the three main challenges to using hydrogen as a fuel source?
There's hardly any hydrogen gas (H2) in the earth's atmosphere, so it must be produced from environmental hydrogen, which is chemically locked up in water and in organic compounds. It tales energy and money to produce H2 and it would take more energy to make than we'd get (negative net energy yield). Fuel cells are the best way to use H2 to produce electricity, but current versions of fuel cells are expensive. Whether or not a hydrogen-based energy system produces less outdoor air pollution and CO2 than a fossil fuel system depends on the H2 is produced.
Plastics
These are everywhere in aquatic environments, and cause damage to animals in their whole form or to smaller organisms when the plastics have started to break down into small particles.
Industrial facilities
These are the second major source of water pollution
Developed countries
These countries have laws that help control point source pollution and discharge of toxic chemicals.
Carbamates
They are broad-spectrum insecticides and are not as toxic as organophosphates to humans though they do show broad, non-target toxicity. Sevin dust is an example.
What is the Goldman Environmental Prize, and what did Maria Gunnoe do to earn one?
This award is considered the "Nobel Prize for the Environment" and it recognizes grassroots environmental leaders from around the world and their extraordinary leaders from around the world and their extraordinary efforts to protect the natural world and human rights. A coal mine began to work on a mountaintop removal on a ridge above her house in 2000 and it flooded her property 7 times, covered her yard with toxic sludge, contaminated her well and groundwater, and forced her family to use bottled water for drinking, cooking, and bathing. The coal company took no responsibility so she turned into a fearless community organizer and advocate for environmental justice in the Appalachian coalfields. She speaks all over the nation and is recognized as an inspiring leader in her fight against some of the world's wealthiest and most powerful coal companies.
Nonpoint source
This type of pollution are broad, diffuse areas, rather than points, from which pollutants enter bodies of water.
secondary recycling
This type of recycling is when materials are converted into different products.
Describe three ways that either new or existing buildings can save energy and money by incorporating different practices into their design.
Use green architecture- use natural lighting, passive solar heating, solar cells, solar hot water heaters, recycled wastewater, and energy-efficient appliances and lighting. Insulate buildings and plug leaks to save money and energy and use less heating/cooling. Use energy-efficient windows- cuts expensive heat losses, lessens cooling costs, and reduces heating system CO2 emissions.
Biological Control
Use of naturally occurring disease organisms, parasites or predators to control pests (ex: Bt)
When a resource has been economically depleted, we can do all of the following, except
Use other supplies.
Hydropower has the potential to provide much more of the world's energy. If hydropower systems continue to be developed, what environmental impacts could result?
Uses kinetic energy of flowing and falling water to produce electricity. Existing reservoirs will fill with silt and become useless faster than new systems are built. Also, there's growing concern over emissions of methane, potent greenhouse gas, from the decomposition of submerged vegetation in hydropower plant reservoirs, especially in warm climates. The world's largest dams together are already the single largest human-caused source of methane. Large land disturbance, and disrupts (aquatic) ecosystems.

Will We Have Enough Usable Water?
We are using available freshwater unsustainably by wasting it, polluting it, and underpricing this irreplaceable natural resource. Freshwater supplies are not evenly distributed, and one of every six people on the planet does not have adequate access to clean water.
Freshwater Is an Irreplaceable Resource That We Are Managing Poorly
We live on a planet that is unique to our solar system because of a precious layer of water—most of it saltwater—covering about 71% of its surface (see Figure 8-2, and Figure 25, Supplement 6). Look in the mirror. What you see is about 60% water, most of it inside your cells. Water is an amazing and irreplaceable chemical with unique properties that help to keep us and other species alive (see Science Focus 3.2). You could survive for several weeks without food, but for only a few days without freshwater, or water that contains very low levels of dissolved salts.

Deep Aquifers Might Be Tapped
With global shortages of freshwater looming, scientists are evaluating deep aquifers as future sources of freshwater. Preliminary results suggest that some of these aquifers hold enough freshwater to support billions of people for centuries. In addition, the quality of freshwater in these aquifers may be much higher than the quality of the freshwater in most rivers and lakes. There are four major concerns about tapping these ancient deposits of freshwater. First, they are nonrenewable and cannot be replenished on a human time scale. Second, little is known about the geological and ecological impacts of pumping large amounts of freshwater from deep aquifers. Third, some deep aquifers flow beneath more than one country and there are no international treaties that govern rights to them. Without such treaties, wars could break out over this resource. Fourth, the costs of tapping deep aquifers are unknown and could be high.
