While you’re sitting there, look up into the branches and think about some of these fascinating facts:

• Wind-blown cottonwood seeds can stay airborne for days before they land. In fact, they can fly longer than any other kind of tree seeds.

• The rings in a cut tree don’t just reveal its age. They can also show signs of environmental changes, like a volcanic eruption or severe drought.

• Trees help improve our water quality as they slow and filter rainfall.

• No other organism on Earth lives as long as a tree.

• A shade tree can help cool your home or office building by as much as 20 degrees in the summertime.
