There are a whopping 3.04 trillion trees on the planet — or 422 trees per human being — according to a Yale-led study. The research team utilized satellite imagery, previous peer-reviewed studies and density information from 400,000 forest plots worldwide to estimate the tree population.
Although that might sound like a lot of trees, human-driven deforestation has had a staggering impact on the world's flora. Researchers estimate that the number of trees on the planet has nearly halved since the dawn of human civilization. More than 15 billion additional trees are lost to human-related causes each year.
"This study highlights how much more effort is needed if we are to restore healthy forests worldwide. They store huge amounts of carbon, are essential for the cycling of nutrients, for water and air quality, and for countless human services." said study lead author Thomas Crowther.
