Scientists Didn't Know We Had This Many Trees

Scientists Discover Seven Times More Trees Exist On Earth – For Now

Previously, the number of trees on our planet was determined by a rough count based on satellite imagery, resulting in a rough count of 400 billion trees on the surface of the Earth.

After scientists and researchers took a closer look using satellite measurements, computer models and more than 420,000 ground-based measurements, they realized that there are more than 3 trillion trees on Earth, making them, as Yale forestry researcher Thomas Crowther put it, “the most prominent organisms on our planet.”

Net Loss of 10 Billion Per Year

The greatest influencer, as you might imagine, when it comes to the health and number of trees on Earth, tends to be human behavior, especially the act of clear cutting and burning trees to clear space.

Every year an estimated 15 billion trees are felled. Only 5 billion of those are replaced each year, which results in a deficit of 10 billion trees per year. "Humans are diminishing that huge population on such a global scale," Crowther told reporters, also mentioning that within about 300 years, all the trees will disappear if the same rate of this destruction keeps pace.

The highest rate of loss takes place in subtropical and tropical climes, which contain about 1.4 trillion of the Earth’s trees - nearly half of all our planet’s forest. However, Canada’s role in the deforestation of the planet is greater than what Canadians may expect.

Canada Leads the Way in Degradation

Unfortunately, Canada lead the world in the global degradation of forests, responsible for 21% of the total. Even countries such as Paraguay, which had 78 percent of its forests destroyed, contributes less to the elimination of trees stocks around the world.

The oil and gas industry is partially to blame, as the infrastructure required has caused fragmentation and degradation of Northern forest habitats. Often, since northern Canada is so remote, forest fires are left to burn themselves out, causing further loss of trees.
