помоги пожалуйста,очень прошу,нужно перевести((Big mining and its increasingly radical opponentsA PLEASANT town in a broad green valley in northern Peru, Cajamarca is the site of one of history's great betrayals. Some 200 yards from the main square, through a Spanish colonial doorway, stands a stone building known as the “Ransom Room”. Though this particular building may in fact have been his prison, in 1532 Atahualpa, the Inca ruler, offered to fill such a room with gold artefacts in order to win freedom from his conquistador captors. He kept his side of the bargain—but was murdered anyway. Now, once again, some people in Cajamarca complain that Peru's gold is being carried off by foreigners—and they are trying to stop it.Astride the Andean watershed an hour north of Cajamarca is Yanacocha, one of the world's biggest and most profitable gold mines. Run by Newmont, a Denver-based company which owns it with Peru's Buenaventura, Yanacocha is a world away from the dark and dangerous gold mines of the past. At five separate sites, giant scoops slice the sides from mountains, loading 300,000 tonnes of rock a day into 250-tonne trucks, each the height of a four-storey building. The rock is laid out in terraces, sealed in black plastic, and injected with cyanide solution. This process yields an ounce of gold from each tonne of rock. So successful has Yanacocha been that its output has soared from 81,000 ounces of gold in 1993 to 3m ounces last year.This headlong expansion has injected wealth into Cajamarca, though it is still one of Peru's poorest departments. The mine has produced fears and resentment too. For a fortnight last September, thousands of protesters blocked the road to the mine; supplies and staff had to be ferried to and fro by helicopter. The protest was against Newmont's decision to prospect on Cerro Quilish, a mountain which locals say feeds streams that supply the city with drinking water. The protesters won hands down. Humbled, Yanacocha agreed to stop prospecting, asked the government to revoke its licence to do so, and issued an unprecedented public apology.
