The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

(CNN) -- Shain Gandee, one of the stars of the MTV reality show "Buckwild," has been found dead along with two other people in Kanawha County, West Virginia, authorities said Monday. "This is a very sad and tragic event," Kanawha County Commissioner Kent Carper said. "We live in a very small community. Our thoughts and prayers are with the Gandee family." Gandee, 21, was found dead in a vehicle along with his uncle, David Dwight Gandee, 48, and Donald Robert Myers, 27, authorities said. 'Buckwild' producer talks about the show "Earlier this day after releasing information Shain Gandee was missing, the Kanawha County Sheriff's Office received word of a disabled vehicle in a wooded area near Thaxton Hollow, Sissonville, Kanawha County WV," said a statement from the Sheriff's Office. "Deputies and members of the Sissonville Volunteer Fire Department used all terrain vehicles to access that vehicle, a 1984 Ford Bronco belonging to the Gandee family. The vehicle was in a muddy area along a worn path. Inside were the bodies of three people." In a subsequent release, the Sheriff's Office said the vehicle was partially submerged in mud. It was uneven but upright; its muffler was below the surface. Mud covered the lower part of the Bronco's passenger side door, but the driver's side, where the younger Gandee sat, was free, the Sheriff's Office said. Gandee was happy with life before death He was one of the nine cast members of "Buckwild." The show follows a group of young adults trying to have fun in Sissonville, West Virginia, pulling stunts such as turning a dump truck into a swimming pool or just riding around the woods on their all-terrain vehicles.

When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison.

Question: "In the last 100 years, how much has the agricultural clearing grown and how is it used?"
