According to the most recent study, there are three trillion trees on earth – more than 420 trees for each person on the planet.
This number was reached by using both ground surveys and satellite data by a team from Yale University headed by Dr. Thomas Crowther. A previous estimate put the global tree count at 400 billion – which means we have about eight times more trees than previously thought.
Before we celebrate, Dr. Crowther is quoted as saying, “It’s not like we’ve discovered a load of new trees; it’s not like we’ve discovered a load of new carbon. So, it’s not good news for the world or bad news that we’ve produced this new number.”
It is thought that humans have already removed at least three trillion trees since the last ice age. We continue to deforest the planet at a rate of 15 billion trees a year, while replanting approximately 5 billion.
With 7.5 billion people on earth, we would each only need to plant 2 trees to more than balance out that equation.
