“China, India making the world a greener place” | SCMP



Wow. Who knew this? I certainly didn't. 
China and India have added the equivalent to an Amazon rainforest of green to the world, largely thanks to agriculture in India and afforestation in China. 
As someone said online in China "at last, some good news!"  
Nasa scientists recorded a 5 per cent increase in the planet's green leaf area since the early 2000s – the equivalent of an extra Amazon rainforest – and were surprised by the cause.
The Nasa study, which was published on February 11 in the journal Nature Sustainability, found some 2 million square miles (about 518 million hectares) of vegetation had been added to the surface of the earth, a quarter of which was contributed by China.
The study found that most of China's contribution was achieved through its initiatives to conserve and expand forests, while more than 80 per cent of India's increase was due to intensive agriculture.
"China and India account for one-third of the greening, but contain only 9 per cent of the planet's land area covered in vegetation – a surprising finding, considering the general notion of land degradation in populous countries from over-exploitation," Chi Chen, the study's lead author, said.
The study analysed data collected from two Nasa satellites between 2000 and 2017.
"When the greening of the Earth was first observed, we thought it was due to a warmer, wetter climate and fertilisation as a result of the added carbon dioxide in the atmosphere," Rama Nemani, a co-author of the study, said.
"Now, with the medium-resolution imaging spectrometer (MODIS) data, we see that humans are also contributing."
