Washington: A new study has estimated that at least 3 trillion trees are currently present on earth. This is much more than the previously estimated figure of 400 billion trees.
The study was carried out by Yale forestry researcher Thomas Crowther whose team used 429,775 ground-based measurements, satellite images and measurements and computer models to arrive at a global figure of 3.04 trillion trees, according to a report in Times of India.
The study was conceptualized when, Crowther was approached by United Nations-affiliated youth group that had set a goal of planting 1 billion trees to fight man-made climate change.
The study estimated that before the dawn of human civilization, there were at least 5.6 trillion trees on earth. But, today more than half of them have been wiped out. The study revealed that at least 15 billion trees are cut every year, but only 5 billion new trees are planted. Therefore, there is a net loss of 10 billion trees every year and at this rate, the earth will be completely devoid of trees within next 300 years.
The youth group-Plant for the Planet has now revised its goal and has set its new target to growing 18 billion trees.
