It turns out that about 8 times as many trees are growing on the earth as forecasts of the past

In the latest research, measuring about 420,000 places in 6 continents / 50 countries around the world, it turned out that on the earth, 8 times as many trees as the past forecast are growing. On the other hand, we found that the current trees are the fewest in history. A movie that explains how much trees are on the planet and how they are decreasing is now on the YouTube site.

The number of trees existing on the earth has been judged from the satellite photograph so far, but in the latest research, it turned out that eight times the tree actually grows. The number is about 3,040 billion.


What is important as "How much tree is growing on the earth?" Is "How dense is it growing?" So, as thousands of people actually walked through the forest and counted the number of trees, the average density of the places where trees grow is also found. That is the green part shown in the image below.


The highest density was in the vicinity of the North Pole, and it seems that one tree was growing in 1 square meter.


However, on the other hand, half of the trees growing on the earth were from the tropical and subtropical regions. These findings are expected to help understand areas where endangered animals can live and to predict how much carbon dioxide is absorbed in trees in which area.


Although I am optimistic when listening to the figure of 3 trillion 400 billion, in fact, 10 billion trees are decreasing annually on Earth.


As of now we can say that we have 400 trees per person ... ...


The amount of trees owned per person is decreasing by 1.4 each year. If trees decrease at this speed, it seems to be difficult to "walk in the forest" either.


Furthermore, before the emergence of human civilization, it turned out that trees were growing in the world that is twice the current number. Europe, where buildings are now lined up, was once a big forest. To preserve the trees that are being lost, various groups now try to regain trees and regain the lost nature.


The newly discovered "how much trees are growing on the earth" "What is the density of each place?" Indicates the fact that the number of forests is decreasing so far in history, and we It fundamentally changed the idea of ​​the earth and the forest that it held, and it is said that "It is what to do from now" was made clear.
