Whence come trees?

As you walk around Saginaw Forest - or actually any area with trees - you might not have wondered where the trees actually came from. I mean, it was probably never a question that you asked. But do you really know where all that "stuff" that makes the tree actually came from?

Before you check out this video from Veritasium, stop for a moment and make a prediction.

For all of you who don't have a background in biology, was your prediction correct?

So now that you know where all the mass of a tree comes from, you might have an additional appreciation for why forests (and also deforestation) is important when thinking about the future.
