How Many Trees Are There On Earth?

A groundbreaking study in September 2015 provided the first map of tree density for the entire planet, confirming that the number of trees on Earth was far larger than scientists had previously thought. Of the planet's approximately 3.04 trillion trees, almost half of them grow in the tropical and subtropical forests. The study also estimated that 15 billion trees are cut down each year, continuing the unfortunate trend of human influence acting as a destructive force on nature.
