Save a what?

Once again, I read where some silly environmentalist advised to cut back on the use of toilet paper to save a tree. Trees are a plant and a crop. Trees are cut down for use and replanted every day, There are more trees in the USA today than when the colonists arrived. The once tree barren great plains are now dotted with trees everywhere. Use less toilet paper to save a tree is like saying, "Don't eat  succotash to save a corn stalk!"---------------Grandpa Gordon
