True (T) or False (F). Considering the total annual harvest of forests in the United States and the total consumption of wood and wood fiber products within our country, the U.S. is a net importer of wood and wood products.
-
True (T)
-
False (F)
Correct Answer
A. True (T)Explanation
True. The United States is a net importer of about 25% of the softwood lumber consumed annually within the country. When all products are considered, including exports of logs, and chips, the U.S. is a net importer of about 9% of the total wood and wood fiber consumed within its borders. Prior to the recent recession, U.S. net imports of wood were 15-20% of domestic consumption. The United States has been a net importer of wood for over 45 years.Rate this question:
-
- 10.
True (T) or False (F). Reduced paper consumption is likely to result in a greater extent of forest cover in the United States.
-
True (T)
-
False (F)
Correct Answer
A. False (F)Explanation
This statement is very likely False. The vast majority of wood used for papermaking in the United States comes from privately-owned forest land, two-thirds of which is in the Southeastern part of the country. Should consumption of paper, and thus pulpwood, decline markedly many forest owners are likely to convert their forested lands to agriculture or some other non-forest use.Rate this question:

Correct Answer
A. True (T)Explanation
True. In 1920 there were an estimated 732 million acres of forest covering the area that now comprises the United States. Today there are 766 million acres of forest. The current forested area is within one percent of the forest area of approximately 755 to 760 million acres that existed in 1907.Rate this question:
-
- 20.
Which of the following statements most accurately describes United States forests:
-
Forest harvest exceeds net growth by 20 percent.
-
Forest harvest exceeds net growth by 5 percent.
-
Forest harvest roughly equals net growth.
-
Net forest growth exceeds harvest by 29 percent.
-
Net forest growth exceeds harvest by more than 100 percent.
Correct Answer
A. Net forest growth exceeds harvest by more than 100 percent.Explanation
Net growth of forests in the United States substantially exceeds harvest. In the most recent assessment of U.S. forest land (USDA-Forest Service, RPA Assessment 2012) net growth was estimated to exceed removals by 105% (e) – i.e. net growth is more than double net removals. These figures do not include growth within areas designated as parks, reserves, or wilderness areas. If growing on all lands were counted the net growth figure would likely be higher than that indicated above.Rate this question:

-
15 percent
-
38 percent
-
63 percent
-
81 percent

Recovered paper provided _____ of the fiber used in manufacturing paper in the United States in 2013.
-
15 percent
-
38 percent
-
63 percent
-
81 percent
Correct Answer
A. 38 percentExplanation
Recovered paper provided about 38.8 percent of the U.S. paper industry's fiber in 2013 (b). The difference between the wastepaper collection rate (63 percent) and the recovered paper use rate (38 percent) is largely traceable to the fact that the United States is the world's largest exporter of waste paper. Virtually all exported wastepaper is also used in making paper and paperboard.Rate this question:

True (T) or False (F). The manufacture of wood construction materials generally results in far lower environmental impacts than when similar construction materials are manufactured from steel, aluminum, plastic, or concrete.
-
True (T)
-
False (F)
Correct Answer
A. True (T)Explanation
True. Well-documented environmental life cycle inventories of various raw materials production processes conducted by research organizations around the world show that wood products can be manufactured with relatively little environmental impact compared to potential alternatives. Even when wood products are compared to cement-based and recycled metal products, energy consumption and associated environmental impacts associated with wood-based materials manufacture are generally substantially lower.Rate this question:
-

True (T) or False (F). The world's most economically developed countries consume a far larger share of the world's industrial raw materials than their collective share of world population.
-
True (T)
-
False (F)
Correct Answer
A. True (T)Explanation
True. As an example of this, a 2004 study commissioned by the United Nations Environment Program (UNEP) found that just five countries – the United States, UK, France, Germany, and Japan – that together accounted for 10.2% of the world population, consumed 28, 33, 40, 44, 45, 45, and 47%, respectively, of the world’s iron, crude steel, zinc, tin, copper, aluminum, and nickel. Cement and wood consumption on a per capita basis was also significantly greater.
Recently, the world’s second most populous country – China – until recently classed as economically underdeveloped,
has begun to consume vast quantities of raw materials. Addition of China to the list above would yield truly stunning consumption numbers.Rate this question:

China's emissions of carbon dioxide in 2012 were greater than those of any other nation, and 90% greater than those of the United States. In that same year, China's per capita emissions of carbon dioxide were:
-
35 percent greater than the U.S.
-
15 percent greater than the U.S.
-
About the same as in the U.S.
-
Less than one-half those of the U.S.
-
Less than one-third those of the U.S.
Correct Answer
A. Less than one-half those of the U.S.Explanation
Carbon dioxide emissions in 2012 for China, the European Union, and the United States were estimated at 9.9, 7.4, and 5.2 billion metric tons, respectively. China’s per capita CO2 emissions in that same year were 7.1 metric tons while emissions for the E.U. were 7.4 metric tons and those of the U.S. 16.4 metric tons. Consequently, China’s per capita CO2 emissions were less than one-half of those of the U.S. in 2012 (d).Rate this question:

The medium (most likely) estimate of the U.S. population in the year 2060 is:
-
220 million
-
319 million
-
420 million
-
511 million
Correct Answer
A. 420 millionExplanation
The projected population of the U.S. in 2060 is 420 million (c), an increase of just over 100 million from mid-year 2014. The population of the U.S. in 1914 was about 99 million.Rate this question:
-
- 27.
China’s current population (mid-year 2014) is 1.36 billion. Assuming a continuation of the current U.S. population growth (0.72% annually), how many years would it take for the U.S. population to become equal to the current population of China?
-
50
-
100
-
200
-
400
-
1,000
Correct Answer
A. 200Explanation
If the U.S. population were to continue growing at a rate of 0.72% annually the U.S. population would surpass China’s current population level in 200 years, or by 2214. At that point the U.S. population would be 4 times larger than it is today.
If the U.S. population were to continue its current rate of growth (a rate of growth that many people would say is negligible) for the next 400 years, the population would increase to over 5.1 billion (the current world population is 7.2 billion). Continuation of the current rate of growth for the next 1,000 years would result in a U.S. population of over 326 billion!
China’s population is also growing, currently at an annual rate of 0.48% annually. If this rate of growth were to continue, China’s population in the year 2100 would approximate 2 billion (as compared to 1.36 billion in 2014).Rate this question:
