請閱讀下面短文，在短文后表格中的空白處填上適當的単詞(注意:每空1個單詞)。

Global warming is a big problem that we have to stop. One of the best things we can do is to plant more trees. Trees can take in carbon dioxide（二氧化碳）in the air and stop global warming.

According to a new report, China is doing a great job of "greening" the world.

A team of scientists at Boston University has been working with NASA to study Earth's green vegetation（植被）. They used a special NASA camera and found that global leaf area has increased by 5 percent since the early 2000s. And China was responsible for 25 percent of that gain, according to the study. That's about one-quarter of the size of the entire Amazon rainforest.

The growth mainly came from China's forest protection programs, NASA said. For example, since 1962, China has been planting trees in Saihanba in Hebei province. It was once a desert. But now, China has turned the area into the country's largest man-made forest.

The Chinese public has also joined in these efforts. Ant Forest in the Alipay app gives users points for doing eco-friendly(環保的) things such as walking and going paperless in the office. Users can then use these points to water and grow their own virtual trees. When the virtual trees are big enough, Ant Forest will plant real trees somewhere in the world. More than 55 million trees have been planted in this way.
