China played a major role, adding 25% to this increase, and India added %, followed by Canada and Russia. The study in the Nature Sustainability journal shows that more than million square kilometers of green leaf area was added globally. Since 2000, there has been a fivepercent increase in global green cover, it said.s green cover, and agriculture added another 32%. In India, 82% of the increase in leaf area was because of agriculture.s land area covered in green plants, Chi Chen told NASA Earth Observatory. That is a surprising finding, considering the land degradation(退化) in countries with large populations.s research team first detected an increase in global green cover in the 1990s but were unsure about what contributed to the increase.
