TEMPO.CO, Jakarta - A new research led by Thomas Crowther from Yale University reveals that the earth has more than 3 trillion trees today, BBC reported. The figure is eight times larger than the best previous estimation of around 400 billion.
The research counted the trees by combining mass of land survey data with satelite images. The result, that is published on journal Nature, shows there are 420 trees available for each individual on the planet.
Dr Crwother, however, warned that the finding does not necessarily a good news because instead of finding new trees or carbon, the research only map existing trees with more accurate approach.
The researchers have plotted 1.39 billion trees in the tropical and subtropical areas, 0.61 trillion in temperature region, and 0.74 trilllion in boreal forest. In addition, the research reveals that only 5 billion trees are newly-planted while there are 15 billion trees cut each year.
