The tree-hugger's equivalent of the endangered-animal-species advocate's "only elephants should wear ivory" saying. Hear, hear!
Nowadays there are plenty of "alternative" materials we can use instead of pulp-fiber in the production of lumber, paper, etc.... only trees should wear wood; we need them --- along with the plankton in the ocean --- for creating our planet's oxygen.
A forest-conservationist's verbal equivalent to dalarge-mammal-lover's "Only elephants should wear ivory" saying.
Tipping trees for making wreaths has never been a good idea --- i.e., only fir trees should wear tips, and it harms the tree to remove them --- but it's not even necessary if you want wreaths to decorate your house, since so many inexpensive and perfectly-suitable artificial wreaths are available that not only look just as good as natural ones, but last for many years if properly cared for.
