　　Building a road through wilderness certainly has avisible impact on local flora and fauna—you'rephysically paving over a slice of what was oncehabitat. But roads have less obvious fects, too.Like the introduction of traffic noise, which also takesa toll. "You can see an oil spill but you can't see a traffic noise spill. So convincing people thatit's important is a little more difficult," said Heidi Ware.

　　Ware is an ornithologist at the Intermountain Bird Observatory in Boise, Idaho. She and hercolleagues studied the reactions by birds to the sounds of vehicles. And they did it withoutpaving the great outdoors. Instead, they mounted 15 pairs of speakers on Douglas fir trees,along a ridge near Boise, and played traffic noise. They thus created what they call a "phantomroad" through the wilderness, which boosted local noise levels 10 decibels higher than those inthe surrounding forest.

　　Turns out just the sounds of traffic scared away a third of the area's usual avian visitors, andcut species diversity too. And birds of multiple species were not able to pack on as much fatto fuel their migrations, when they were forced to dine to the soundtrack of traffic.

　　Follow-up experiments in the lab found that, when it's noisy, birds spend a lot less time headdown, pecking at food, and a lot more time scanning their surroundings.

　　Ware says Yosemite, Glacier and Rocky Mountain National Parks all have roads that are busyenough to produce these fects. And, short of closing park roads to traffic, she says thingslike rubberized asphalt and lower speed limits could help cut the noise. "Glacier National Park isgoing to put up signs, that instead of showing your speed and preventing people fromspeeding, it's going to show how loud their car is on the road." Which, hopully, will continueto encourage wilderness lovers to leave no trace—visible or audible.

　　The main idea of the first paragraph is that the presence of a road through awilderness area ____________________

　　(A) affects the environment in ways that can be hard to recognize.

　　(B) increases the level of unnatural noise and decreases the level of natural noise.

　　(C) reduces the number of plants that serve as a source of food for wildlife.

　　(D) leaves the area vulnerable to oil spills and other physical damage caused by cars.
