This is a view from the window of my studio. It is a "finger-painting" I did in the "Brushes" app on my iPad.
The tree in the foreground is a white ash, which is dying as a result of the emerald ash borer. The painting was made at night, and the lower dead branches appeared bright, whereas the upper ones were dark.
Hundreds of trees in the city are dead or dying.
Why should we care? Some studies indicate the widespread tree diseases are the result of global climate changes brought about by our choices.
