 This study examined changes in vegetation activity over the past three decades using satellite data. It found that global vegetation has been increasing at a rate of 0.46 times 10 to the power of negative 3 per year since 1982. However, this increase was not consistent across all regions. Some areas experienced a decrease in vegetation while others experienced an increase. The authors attributed these differences to both natural and anthropogenic factors such as temperature and precipitation levels, as well as human activity. They also found that human activity had a greater impact on the magnitude of the increase in vegetation than did climate factors. This article was authored by Yalu, Yanli, Shuanchingli, and others.
