The best musical instrument bows are made out of the Pernambuco tree. They hold their shape for centuries, and they draw the most beautiful sound out of the instrument they are played with.
Sadly, the Pernambuco, or the Brazilwood, is a rare tree in Brazil that has been exploited to near-extinction.
Thankfully, traditional bow craftsmen are working to conserve the Pernambuco and plant new groves of the tree.
But rival carbon-fiber bow makers, threatened by all that is natural and pure, go around chopping down the Pernambuco and burning them for firewood.
The lesson to be learned?
Play the oboe.
