The first national park in the world, fitflop?? Yellowstone National Park in the United States was born in 1872. It opened the way for mankind to plan to protect the natural environment and wildlife. Our country"s natural ecological protection work started late, more than a hundred years later than advanced European and American countries. Strictly speaking, it was only in the late 1980s that our country included this work at the national level, and implemented protection in a focused and selective manner. The real implementation of this work across the country was at the beginning of the twentieth century. In 1998, a catastrophic flood in the Yangtze River basin sounded the alarm of ecological deterioration to the Chinese. If we do not pay attention to the protection of the natural environment,fitflop similar natural disasters will happen frequently. This disaster is just a prelude to the deterioration of the ecological environment. Since this period, fitflop?? policies and regulations have been introduced, such as stopping natural forest logging, returning farmland to forests, returning grazing land to grassland, and returning farmland to lakes. At the same time, a large number of nature and wildlife reserves have emerged one after another from the frontier to the inland. As of 2019, fitflop ? there are 2,750 nature reserves nationwide, with a total area of ??1.47 million square kilometers. fitflop The establishment of these protected areas not only effectively curbed the deteriorating trend of China"s ecological environment, but also provided necessary living space for wild animals. Qinghai Sanjiangyuan National Park, China"s first national park, has achieved remarkable results through the unremitting efforts of the government and local residents. After 20 years of protection, the ecological degradation trend of the Sanjiangyuan area has been initially curbed, which has increased the water resources of the China Water Tower by nearly 8 billion cubic meters, the overall grass production has increased by 30%, and the Tibetan antelope has increased to 60,000. There are about 36,000 wild donkeys in Tibet, the number of white-lipped deer and wild yaks is about 10,000, fitflop??and the population of snow leopards ranges from 392 to 659. There are rewards for what you pay. The improvement of the natural ecology of the Three Rivers Source has not only provided a broad living space for wild animals, but also made the water volume and water quality of the three major rivers of the Yangtze River, Yellow River and Lancang River more abundant and clearer. This massive ecological restoration project that has attracted worldwide attention not only benefits two-fifths of China"s population,fitflop but also benefits hundreds of millions of people in downstream countries. fitflop??
