Study: World Still Has Many Unknown Trees - Yu Obata
According to a new study, there are 73,300 tree species in the world. About 9,200 species haven’t been identified by science though they can exist on the Earth mathematically. A team of Roberto Cazzolla Gatti of the University of Bologna in Italy estimates that in South America, there are 27,000 known tree species, while 4,000 are unknown. In addition, there are a lot of known species and unknown species in each area of the world.
Study co-writer Peter Reich of the University of Michigan and University of Minnesota says by measuring the number of trees, we can contribute to tree and forest conservation effort. Though he believes that tree species diversity has some advantages to maintain healthy forests, tree species extinct because of deforestation and climate change.
Jingjing Liang of Purdue University in Indiana, a co-writer of the study said we need to learn more about the Earth to protect and preserve them for future generations.
I chose this topic not only because I’m interested in nature, but also I’d like to tell you how wonderful nature is. This story made me excited because there are large number of things we don’t know about the Earth even though science technology progresses.
I know nature has countless things and information but it is unexpected that how large number of unknown trees are there. I'm so excited, too! I want to seek such information from now on in my major.

Hi Hinata, thank you for your comment! I can't imagine a number of trees which people still don't know. You will be able to find a new fact about your major if you try!
DeleteTrees are certainly wonderful things. I love walking among them and marveling at their size and strength and the various other plants that make their homes on their trunks and branches. More than ever, we need to protect them, don't we?
ReplyDeleteDo you often have a chance to go for a walk in the woods?

Hi David, thank you for your comment! Actually, I like walking in the woods, but I don't go for a walk often. In Niigata Prefecture, there is a famous woods which is called Bijin-bayashi in Tokamachi City. There are a lot of beech forest. When I visited there, I felt healing power from them. I hope that you spend enjoyable time with trees!

Hi Chinatsu, thank you for your comment! We can't imagine the large number of trees, can we? I think the nature is beautiful as well as mysterious because there are a lot of things we don't know.
DeleteHi Yu,
ReplyDeleteThank you for sharing your fascinating story,
I did not know unknown trees existence in the world, but I knew the “Baobab tree.”
The "baobab tree" appears in the fairy tale "Prince of the Stars".
And I am not sure about it, but it is said that in ancient times, royalty and elders gathered under a huge baobab to make important decisions.
It was believed that it was not only provided a precious shade, but that the holy soul that dwells in it would surely lead to wise decisions if a meeting were held under the giant tree.
Do you know it?
As you informed, we need to consider our planet and nature seriously sooner than later.
Thank you for reminding and providing me this problem.
I hope that you would continue to raise or share an intriguing case for us from now and so on.
Thank you!
