Spring is here. Did you plant trees on Tree-Planting Day? Everyone knows that climate change is a serious problem these days. People have a lot of work to do in order to prevent it. One of the best ways is to plant more trees.

According to a study by NASA, the Earth’s green leaf area has increased by 5 percent, or over 5 million square kilometers since 2000. China is responsible for 25 percent of the increase. That’s about one square of the size of the whole Amazon rainforest.

Over the past twenty years, China has made great efforts to green the land in order to fight soil erosion (水土流失) and air pollution. It is one of the most successful countries in greening the desert.

For example since 1962, China had been planting trees in Saihanba in Hebei province. It was once a barren(贫瘠) area. After overcoming many difficulties, foresters have turned the area into China’s largest man-made forest. Another example is the Kubuqi Desert, which is near the Yellow River in Inner Mongolia. It was once the source(来源) of sandstorms in Beijing. But now, about one third of the Kubuqi Desert is covered with trees, and sandstorms are less common. Mu Us Desert was also known for its sandstorms many years ago. But now, one-quarter of the desert has been turned into forest.

In a word, planting trees is really important to us. Let’s take part in planting trees to make our earth greener and more beautiful.
