NASA点赞中国和印度引领全球绿化，网友有一个问题......

近日，NASA公布了一项研究成果，向世界传达了两个好消息：

过去20年，地球变绿了。

作为人口大国的中国和印度正引领世界绿化。

点赞中国：为全球绿化贡献25% 

研究指出，过去近20年，中印两国共为全球绿化贡献31.8%。

而中国凭着仅占全球6.6%的植被面积为全球绿化做出了四分之一的贡献。

中国的贡献中有42%源自植树造林，而印度超过80%的绿化增长来自于农业用地。

China and India, two countries often criticized for flouting environmental norms, are leaders in enhancing global tree cover, a new study based on NASA satellite data revealed. 

They contributed a combined 31.8 percent to the total global new leaf area between 2000 and 2017. China emerged as a major contributor, adding 25 percent to this increase, India added 6.8 percent.

The study, titled China and India lead in the greening of the world through land-use management, published in the Nature Sustainability journal shows that more than 5.5 million square km of extra green leaf area was added globally.

Since 2000, there has been a five-percent increase in global green cover, it said.

"The greening over the last two decades represents an increase in leaf area on plants and trees equivalent to the areal span of the entire Amazonian rainforests," Chi Chen, a Boston University researcher and lead of the study told Nature Sustainability.  

Extensive plantation drives to conserve forest in China contributed nearly 42 percent to the country's green cover, and agriculture added another 32 percent. In India, 82 percent of the increase in leaf area was due to agriculture. 

"China and India account for one-third of the greening, but contain only nine percent of the planet's land area covered in vegetation," Chi Chen told NASA Earth Observatory. 

"That is a surprising finding, considering the general notion of land degradation in populous countries from overexploitation."

Boston University's research team first detected an increase in global green cover in the 1990s but were clueless about what contributed to the increase. 

They used the moderate resolution imaging spectroradiometer (MODIS) instruments on NASA's Terra and Aqua satellites data to measure the increase in leaf cover on a regional basis.

高兴之余，中国的网友们问了一个大家比较关心的问题：

今天，蚂蚁森林发文回应了。

蚂蚁森林表示，跟全国的绿色成绩单相比，蚂蚁森林很小，但在NASA公布的图中中国最绿的部分中，有蚂蚁森林的内蒙古磴口地块。

所以说，你们的梭梭树长得还好嘛？
