Soil erosion is the most prominent ecological issue in the development of western China. There are about 91 million acres of sloped farmland across the country that need to be returned to forest, of which the western region accounts for 70%. The national target for the area of farmland to be returned to forest in the western region was set at 5.15 million acres in 2007, and the area is to increase by 12% each year. Starting from 2007, how many years will it take for the western region to completely return all sloped farmland to forest? (Given that $\log_{1.12}{2.4843} \approx 8.0297$)
