    United States population growth is near zero, with the population expected to stabilize by about 2030.

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. The population of the United States is growing faster than all developed nations except Australia and Luxembourg - about 0.9% to 1% per year. At that rate of growth the U.S. population will reach roughly 439 million by 2050 and 571 million by 2100. The U.S. population is currently (Jan. 2010) 308 million.

    Rate this question:

  • 5. 

    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:

  • 6. 

    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 29% 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 15-20% of the total wood and wood fiber consumed within its borders. The United States has been a net importer of wood for over 40 years.

    Rate this question:

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. The U.S. is today a net importer of most categories of industrial raw materials, including metals, Portland and masonry cement, petroleum (the basis for plastics), and wood and wood products. The 2008 U.S. import situation (the most recent year for which data is available) is outlined in the document available at: http://www.dovetailinc.org/files/Imports.pdf

    Rate this question:

  • 9. 

    The population of the United States in 1960 (50 years ago) was 181 million. On January 12, 2010 the U.S. population was ________________.

    • 187 million

    • 220 million

    • 308 million

    • 459 million

    Correct Answer
    A. 308 million

    The population of the United States in mid-January 2010 was about 308 million (c).

    Rate this question:

  • 10. 

    The geographic area that encompasses the United States today has a greater extent of forest coverage than the same geographic area did in 1920.

    • True (T)

    • False (F)

    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 751 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 and as recently as 1970.

    Rate this question:

  • 11. 

    Assuming a growth rate of 5% annually, the population of the United States would surpass the current population of China by 2040.

    • True (T)

    • False (F)

    Correct Answer
    A. True (T)
    Explanation
    True. At a 5% annual growth rate the population would quadruple in only 28 years, bringing the number of U.S. residents to over 1.2 billion. It is interesting to note that any population will increase by 1,024 times for each 10 times that it doubles. So at an annual growth rate of 5%, only 120 years are needed for 10 doublings to occur. At a 3% annual growth rate, 233 years would result in 10 doublings. Even at a growth rate as low as 1% annually, 10 doublings will occur in 700 years - still a relatively short time in the big scheme of things. Were the U.S. population to increase by 1,024 times, the nation would boast 315 billion residents, equivalent to 46 times the current world population.

    Rate this question:

  • 12.

    Rate this question:

  • 14. 

    As originally established, it was never intended that the National Forests of the United States would be periodically harvested to obtain timber that would be used in meeting the nation's need for wood.

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. One of the specifically stated reasons for establishment of the National Forests was to ensure a continuous supply of wood for the citizens of the United States.

    Rate this question:

  • 15. 

    The estimated world population in the year 2050 is about:

    • 3.4 billion

    • 6.8 billion

    • 9.3 billion

    • 11.5 billion

    Correct Answer
    A. 9.3 billion
    Explanation
    The medium projection of world population for the year 2050 by the International Programs Center of the U.S. Census Bureau is very close to that of the Population Reference Bureau; both are about 9.3 billion (c).

    Rate this question:

  • 16.

    Rate this question:

  • 17. 

    At current rates of deforestation, 40 percent of current forests in the United States will be lost by the middle of this century.

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. Forests actually increased in area coverage in the United States between 1985 and 2009. However, due to continuing growth of urban areas and building of highways, it is predicted that 3 to 5% of the current area of forest land in the U.S. could by lost by 2050.

    Rate this question:

  • 18. 

    Populations of elk, pronghorn antelope, and wild turkey have declined significantly in the United States over the past 60 years.

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. The populations of all these species have increased by over 1,000% (10 x) over the past 60 years. The populations of many other species, including the American bald eagle, have increased dramatically as well.

    Rate this question:

  • 19. 

    Recovered paper provided _____% of the U.S. paper industry's fiber in 2008.

    • 12 percent

    • 34 percent

    • 51 percent

    • 86 percent

    Correct Answer
    A. 34 percent
    Explanation
    Recovered paper provided about 34 percent (b) of the U.S. paper industry's fiber in 2008. The difference between the wastepaper collection rate (57 percent) and the recovered paper use rate (34 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:

  • 20. 

    The population of the world is currently increasing at a rate of 8,600 people per _______.

    • Month

    • Week

    • Day

    • Hour

    Correct Answer
    A. Hour
    Explanation
    The world population is currently increasing at an estimated rate of 8,607 per hour (d).

    Rate this question:

  • 21. 

    In the U.S. and globally, more species of plants and animals have been driven to extinction by logging activity than any other activity of humankind.

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. There is no documented evidence of even one plant or animal species having been driven to extinction by logging activity in the United States. The answer to this question is less clear globally, but it is evident that logging is but one of a myriad of human activities, including land clearing for agriculture, urban and infrastructure development, mining, and industrial production, placing pressure on native species.

    Rate this question:

    Explanation
    In 2008 (the most recent year for which statistics are available), 57.4 percent (c) of all paper used in the United States was collected for reuse.

    Rate this question:

  • 23. 

    More extensive recycling of paper could reduce harvesting of forests in the United States by 60 percent or more.

    • True (T)

    • False (F)

    Correct Answer
    A. False (F)
    Explanation
    False. Several recent studies have shown that while paper recycling is extremely important, and a major contributor to reducing demand for virgin pulpwood, increasing recycling to the maximum level allowed by current technology would have the effect of reducing demand for virgin fiber by only 12-13 percent. Moreover, when taking into consideration the time that will be required to move to the technological limit of recycling, and the population growth that will occur in the meantime, it is likely that demand for virgin fiber will continue to increase, even with aggressive recycling programs.

    Rate this question:

  • 24.

    • 33 percent

    • 17 percent

    Correct Answer
    A. 72 percent
    Explanation
    (a) There are 751 million acres of forests in the U.S. today, about 72% of the 1.044 billion acres of forests estimated to have covered what is now the United States in the year 1600.

    Rate this question:

  • 25. 

    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 72 percent.

    Correct Answer
    A. Net forest growth exceeds harvest by 72 percent.
    Explanation
    (e) 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 2010) net growth was estimated to exceed removals by 72% (e). When all lands are counted (including those forest lands designated as reserves or preserves) the net growth to harvest ratios are higher than those indicated above.
