(c) four dams
3. The U.S. Forest Service timber sales program operates at a net loss each year. By how much?

(b) $2 billion
(c) $7.2 million
4. The greatest number of redwoods are lost each year to which of the following causes?

5. True or False: Gasoline naturally contains lead, which must be removed to make unleaded gasoline.
6. What has former Sierra Club President Adam Werbach been doing these days?

8. What is the highway gas mileage of the new hybrid gas/electric Honda
9. How many new members joined the Sierra Club as a result of the summer 2000 canvassing drive to increase membership?
10. Twenty-five percent of all urban trips in Europe are accomplished by public transit. What percentage are accomplished by public transit in the United States?
(a) 4 percent
(b) 10 percent
(c) 17.2 percent
11. How many current members of the Sierra Club joined before 1930?
1. (b) - Throughout history, shifts in temperature have occurred at a rate of a few degrees over thousands of years. Considering that temperatures in some regions of the world have risen by 5 degrees Fahrenheit over only a century, we need to stem the tide of man-made global warming.
2. (c) - Biologists cite the four dams located on the Lower Snake River, along with the four lower Columbia River dams, as the cause of at least 80 percent of human-inflicted Snake Basin salmon mortalities. Concrete dams, grinding turbines and slackwater reservoirs are pushing the world's salmon stocks toward extinction.
3. (b) - According to the General Accounting Office, from 1992-1997 the U.S. Forest Service's logging program lost $2 billion. The GAO concluded that the program is "largely driven by commercial rather than safety considerations," often selecting the largest, commercially valuable trees. Cutting larger trees reduces shade, creates hotter and drier conditions and leaves behind flammable "slash debris."
7. (a) - Wiggling through a loophole designating SUVs as "light trucks," SUVs are guzzling twice as much gas and spewing out 47 percent more air pollution than the average American car. More startling is the fact that the technology exists to make SUVs as fuel-efficient as today's compact car!
