Oh, Christmas Tree (1986, to the tune of Oh Tannenbaum”)

Oh Christmas tree, Oh Christmas tree,
How green were once your branches
Oh Christmas tree, Oh Christmas tree,
How yellow now your branches
We think it’s something in the air,
But ozone? Sulfur? And from where?
Oh Christmas tree, Oh Christmas tree,
How brown are now your branches

Remember acid rain? Now it’s more insects, at least in our area. Global change?
