I chose this song because it illustrates the place of trees in the cultural USA. There are songs written about trees, or lyrics written that include trees. They are important to our culture.
The picture is because of the bough that hangs over the footbridge.
If one scans the songs that illustrate our country, be it, the national anthem, songs like "God bless America,' and the list goes on; they all have references to the natural world.
"America the Beautiful" in it's opening paragraph paints a picture of the natural world that is this country. Every American should embrace the beauty of this country and protect it.
