...roads that crisscross the national forests. "They are the heart of a lot of controversy," says Marty Hayden, director of policy for the Earthjustice Legal Defense Fund. Environmentalists complain that the roads, cut for the timber companies and maintained by the Forest Service, are degrading watersheds, filling streams with silt and subdividing wildlife habitats. "It is simply time to stop logging our national forests," says Sierra Club executive director Carl Pope...
...dino days. Amid the shallow streams of a broad floodplain, scores of huge, grazing female dinosaurs were making their nests and hovering near their eggs, as their predecessors had doubtless done for ages untold. But their tranquillity was suddenly disturbed. Out of nowhere came a flood of mud and silt, scattering the lumbering beasts and burying their progeny. The lively dinosaur nursery was lost forever...
Although essentially a mainstream Republican, Saxton has split with many in his party by voting often in favor of gun control and environmental protection.

This formula has increased his margin of victory in each of the past three elections, making the well-financed Saxton a formidable incumbent...
There is still hope that archaeologists can solve this mystery, as well as dozens of other unanswered questions about the Olmec. Most of the sites have barely been studied, and with good reason. Annual floods smother the land with thick layers of silt that dry into impenetrable clay. What's more, says Diehl, "about 80% of the entire Olmec territory in southern Mexico has been converted in the past 20 years from jungle to cow pastures and sugar-cane fields.

They fear that a dam so large on the notoriously muddy Yangtze will lead to dangerous buildups of silt in some parts of the river, creating new obstacles to navigation and causing floods upstream. Chinese officials respond that both big and small dams are needed. Indeed, 10 projects smaller than Three Gorges, with a total capacity of nearly 12,000 megawatts, are under construction on the upper reaches...
