Thank you. It makes me so sad when humans just cut down large trees that take hundreds of years to grow. Also. The larger the tree the more carbon they take in from the atmosphere. You can look up studies published on that fact.

Hour long explanation pls
I bet that 3000 year old oak that was unnessarily cut down a few years ago could tell us so much and be a tangible piece of evidence for climate change deniers. Not that tangible evidence would sway selfish idiots like us pres. But ah… cest la vie
