To all tree-lovers out there, we have both good news and bad news for you!
The good news is that: Even with billions of trees being cut down every year, a new study estimates there are seven-and-a-half times more trees on Earth than previously believed: 3.04 trillion, to be precise — or roughly a ratio of 422 trees is to one person. So, there’s exactly a staggering trillion trees are left on earth that even researchers were surprised.
I don’t know what I would have guessed, but I was certainly surprised to find that we were talking about trillions. Trees are among the most prominent and critical organisms on Earth, yet we are only recently beginning to comprehend their global extent and distribution,” says Thomas Crowther, the lead author of the study.
According to NBC News report, the researches have found that the largest forest areas are in the tropics, which are home to about 43 percent of the world’s trees. About 24 percent are in boreal regions and 20 percent in temperate regions.
The 3 trillion figure is seven and a half times more than the previous estimate of 400 billion trees worldwide as of 2005.
Crowther says, human activity has the biggest impact on tree numbers, deforestation, changes in land use, and forest management which have contributed for a loss of more than 15 billion trees a year.
We’ve nearly halved the number of trees on the planet, and we’ve seen the impacts on climate and human health as a result. This study highlights how much more effort is needed if we are to restore healthy forests worldwide.”
So, to clear things out, we are having a drastic effect on Earth’s ecosystem. Yes, there are currently 422 trees per person in the world, but if current trends continue, that will fall to 214 in 150 years. It’s a sobering thought to realize just how much of an impact we are having on this planet of ours!
