Genghis Khan the GREEN: Invader killed so many people that carbon levels plummeted
Genghis Khan has been branded the greenest invader in history - after his murderous conquests killed so many people that huge swathes of cultivated land returned to forest.
The Mongol leader, who established a vast empire between the 13th and 14th centuries, helped remove nearly 700million tons of carbon from the atmosphere, claims a new study.
The deaths of 40million people meant that large areas of cultivated land grew thick once again with trees, which absorb carbon dioxide from the atmosphere.
And, although his methods may be difficult for environmentalists to accept, ecologists believe it may be the first ever case of successful manmade global cooling.
‘It's a common misconception that the human impact on climate began with the large-scale burning of coal and oil in the industrial era,’ said Julia Pongratz, who headed the research by the Carnegie Institution's Department of Global Ecology....
