Yale scientists estimate the number of trees on Earth

Scientists led by Thomas Crowther of Yale University have calculated the total number of trees based on satellite imagery and research in selected areas.

According to these data, there are a total of trillions of trees on Earth 3,04.

Most trees grow in the tropics, but the highest density is in the boreal forests, that is, the coniferous forests of the temperate zone, located south of the tundra.

The reason for this study was the request of a youth organization working under the aegis of the UN and set out to plant a billion trees. The organization turned to Crowther with the question of whether global warming would slow down if they reached their goal, but he came to the conclusion that he could not answer until he knew the exact number of trees on Earth.

According to Crowther, the number set by him cannot be regarded as a good or bad indicator. However, as he stresses, ultimately, the number of trees on Earth is determined by people: 15 billions are cut down every year, accounting for only five billion new ones, and thus the number of trees annually decreases by ten billion annually.

As computer models have shown, before human civilization on Earth, there were 5,6 trillions of trees.
