sentences:  Fujian's slow development in its early days has proved a blessing for the province's ecology; today, the province has the highest forest coverage rate and the most diverse biosphere in China whereas central China suffers from severe overpopulation and displays severe signs of soil erosion, with frequent droughts and floods due to lack of forest coverage.Development has been accompanied by a large influx of population from the overpopulated areas in the north and west, and much of the farmland and forest, as well as cultural heritage sites such as the temples of king Wuzhu, have given way to ubiquitous high-rise buildings.Fujian faces challenges at all levels to sustain development while at the same time preserving Fujian's natural and cultural heritage.
