The. 2 2 2 2 scientists have been working for years to revive the american chestnut, a large tree that once covered the eastern part of the country and provided food for humans and animals. The like. The tree usually lived for hundreds of years and made up an important part of the eastern american tree canopy. But beginning in the early 20th century, the tree was affected by something called chestnut blight. A fungal disease that came from the invasive japanese chestnut beginning in 19 o 4 and spanning the entirety of the 20th century. It is estimated that the blake killed between 4 and 6000000000 american chestnut trees. Now only stumps and root systems remain. They produce young saplings which are almost immediately infected with chestnut light and then they die it. There are now only between 60800 american chestnut trees that survive. And theyre all in the northern part of the state of michigan. Several groups of scientists are working to revive the american, just not including a gr
When i was a little boy growing up in the us state of pennsylvania, we had thousands and thousands of chestnut trees in the area. We used to throw the chestnuts at each other for fun, and our parents would gather them and roast them as a snack. But then disease struck the american chest, not populations. I havent seen a chestnut tree in decades. Theyre almost all gone. Scientists now say that theyve come up with a plan to revive the american chest, not through genetic engineering, to something that might sound like a great idea. But is it . Its never been done before, and we have literally no idea what it will do to other trees as its pollen is spread by the winds.

Forestry. Those scientists had the idea to insert the oxalate oxidation gene from wheat into the dna of the american chestnut to degrade the oxalic acid produced by chestnut light. In 2021. These scientists asked the government permission to introduce the newly genetically modified trees into the wild. Thats great, right. Well, no, actually, its not great. First, we have no idea what the Environmental Impact will be of producing a genetically modified tree into nature. Its never been done before. And even if we had an idea of what would happen, we still dont know what would happen. 5100, even 200 years from now. Remember, these trees live for centuries. And perhaps most disturbingly the same. Scientists recently made a very serious mistake. Instead of using something called the 58 pollinate trees in their research plots, they accidentally use something called d 54, which has o x. So dna in a different part of its genome. Almost all of the thousands of test trees are d. 54. 00 is not th
