There are an estimated 3.04 trillion trees in the world. This figure is much higher than previous estimates, which were around 400 billion trees. The calculation was based on a combination of satellite imaging and ground-based forest plot data worldwide. Approximately 1.4 trillion of these trees are located near the Equator in tropical or subtropical forests, with the Amazon rainforest alone hosting about 390 billion trees. The number of trees per person on Earth is roughly 400 to 422. Human activities have significantly impacted tree numbers, with about 15 billion trees cut down each year, and since the onset of agriculture 12,000 years ago, the total number of trees on Earth has dropped by about 46% from an initial 6 trillion trees. In addition to the quantity of trees, there are approximately 73,000 different tree species globally, with around 9,000 species yet to be discovered. Thus, the global tree population stands at a staggering 3.04 trillion trees today, distributed unevenly across different continents and ecosystems.
