With my mod hat on, I'm going to allow most if not all JustinTheTrees videos because he does at least some woodworking in each. Two popular series of his include making a map of the US out of each state's offical tree, and making ice cream from a chosen tree, including making a bowl and spoon from its wood.

He talks about the trees themselves a lot, their habitat and range, their niche and life cycle, and their properties as building and cooking material. And that I think is also of interest to a woodworking community.
