In fact, populations of each of these species within the U.S. have increased by at least 800 to 1,000 percent over the past 50 years.

True (T) or False (F):

Considering the total annual harvest of forests in the United States and the total consumption of wood and fiber products within our country, the U.S. is a net importer of wood

and wood products.

True (T) or False (F):

Considering the total annual harvest of forests in the United States and the total consumption of wood and fiber products within our country, the U.S. is a net importer of wood

and wood products.

The United States is a Net Importer of Wood and Wood Products

Net U.S. imports of wood and wood products amounted to about 20 percent of total wood consumption and 36 percent of construction lumber consumed in 2006.

When waste paper exports are included in the net import

calculation, the U.S. net import figure for wood and wood

products drops to 2-3 percent.

As a percentage of all the paper used in the United States in 2006 _____ was recovered for reuse.

• 2.9 percent

• 6.5 percent

• 14.7 percent• 29.3 percent• 53.4 percent• 66.1 percent

True (T) or False (F). More extensive recycling of paper could reduce harvesting of forests in the U.S. by 60 percent or more.

True (T) or False (F). More extensive recycling of paper could reduce harvesting of forests in the U.S. by 60 percent or more.

Were paper recycling in the U.S. to go to the limit of technology worldwide the domestic timber harvest could be

reduced by about 12-13%.

The building material that can be produced with the least impact on the environment is:

• brick• concrete• aluminum• virgin steel• recycled steel• wood• plastic

The manufacture and use of all construction materials results in

environmental impacts. The impacts, differ considerably however.

If, for example, an interior wall of a house is constructed using steel rather than wood studs, the result is a large increase in energy consumption and

emissions to air and water.
