But a meter is not flexible. Just imagine if the tree you are measuring grows. How do you measure the tree once it is taller than a meter?
No, no. We need a tree committee that sets the length of the meter based on the current tree growing season.
And then we need tree bank companies to give additional centimeters to tree growers who run out of meters.
