I don't know why a 16 year old would fell the Sycamore Gap tree, but I do know that all children have ever witnessed is nature treated as a commodity, everything else prioritised above the natural environment. The blame for this act doesn't really lie with one child.
It is sad. I was sad too, but trees are felled all the time, the natural environment around us plundered and spoiled. Get that sad/angry every day! And not with children, get angry on behalf of the children.
