China Gets Greener
President Xi Jinping said, “Clear waters and lush mountains are invaluable assets（绿水青山就是金山银山）.” With the efforts of China’s government and its people, the rate of forest coverage（森林覆盖率） in China has reached 22.96%, compared to 5.05% forty

years ago, according to a recent report from the State Forestry and Grassland Administration （SFGA）.
Over the past forty years, China planted billions of trees as part of its fight against expanding（延伸的） deserts, mostly in its north. Each year, people sow seedlings（播种） over an area nearly the size of Ireland, according to Nature.
In 1978, China began a nationwide tree-planting program known as the Three North Shelterbelt Forest Program, also known as “the Great Green Wall”. It has helped to plant more than 66 billion trees across 13 provinces in the country’s north to act as windbreaks（防风林）, according to China Daily.
Since 2018, SFGA has made more efforts to build a greener country. Its purpose is to grow at least 6.7 million hectares（公顷） of forest every year in the next 15 years. Besides planting more trees, China has tried to bring back grasslands. It has also used strict forest protection methods and banned（禁止） all commercial logging（商业伐木） since last August.
The high-speed growth of forests cannot happen without public participation（参与）. For example, Ant Forest, an Alipay mobile payment app, plants real trees for users who get “green energy” by taking part in low-carbon（低碳） activities. Since 2016, it has helped to plant about 122 million trees in China’s driest areas.
China was praised as “one of the most successful countries worldwide in greening the desert” by United Nations Environment Program Executive Director Erik Solheim.
