The total number of trees on the planet is estimated to be around 3 trillion according to a recent global census. This census was conducted with the combination of satellite images, forest inventories and supercomputing technologies.
A new website called Global Forest Watch combines all of this data for anyone to monitor the current tree population as well as get involved in initiatives around the world.
How many trees are there in the world?
Thomas Crowther, a postdoctoral fellow at the Yale School of Forestry and Environmental Studies In Connecticut, said: "Trees are among the most prominent and critical organisms on Earth, yet we are only recently beginning to comprehend their global extent and distribution."
It is no surprise that human activity was found as the main reason for the loss of trees. Deforestation combined with land-use changes and forest-management practices contribute to the loss of 15 billion trees worldwide every year, experts say.
"We've nearly halved the number of trees on the planet, and we've seen the impacts on climate and human health as a result," Crowther said. "This study highlights how much more effort is needed if we are to restore healthy forests worldwide."
