About that Christmas tree.

I said it's okay — and green enough — to get an artificial Christmas tree. Then Professor Yin came in with some scary stuff about lead, and Professor Bainbridge says don't get a tree at all, and don't even get presents — give it all to charity.

What's the best solution to the Christmas tree problem?
	A real tree, a cut tree. Follow tradition!
	A nice new artificial tree. The lead problem is solved, right?
	Some sort of potted tree, that you reuse or replant or something.
	No tree at all!
