t on the Baker and Pascua rivers, but dams have also been proposed on others, including the famed Futaleuf� River in Chile and Santa Cruz river in Argentina. The dams will affect the minimum ecological flows and threaten the fishing, wilderness-tourism and agricultural interests along the river. The electricity would be fed into high-tension lines (to be built by a Canadian company) and taken 1,200 miles (1,900 km) north to the industry and mining hub around Santiago. The lines would cut through a number of previously pristine national parks and protected areas. The Chilean government considers the power to be essential for economic growth, while opponents claim it will destroy Patagonia's growing tourism industry. No evidence has been produced from the experience in other nations that the presence of electrical transmission lines has significantly affected tourism. In fact, opponents of the program have utilized billboard advertising in Chile, which superimposes images of power lines over scenes of Torres del Paine National Park, where no proposals for such lines have been made
