Leonardo Di Caprio’s latest climate change documentary is well worth watching for the riveting coverage of environmental problems around the world. But it begs the question, what about solutions? If oil is death, and water is life, what then is alcohol? Furthermore, what is trash? These diverse “carbons” can become whatever humans need them to be, including a clean, scalable replacement for petroleum fuels. Perhaps Mr. DiCaprio will one day agree to star in “Alcohol Fuels: A Giant Unchained” and people all over the world will be the main characters in their own carbon subplots and join forces to help humanity snatch a much needed victory from the jaws of carbon defeat. Responding effectively to climate change risks isn’t rocket science or political theater, it’s as real as life gets and in our own faces. Winning one of humanity’s greatest challenges for the home team would make a great movie. But not until there’s a deluge of clean alcohol fuel and a lot less trash.
