“The science is also clear about how we might do this. Build renewable energy sources, transmission lines to carry that energy where needed, and batteries to store that energy, which would push aside fossil fuels. Stop heating and cooking with dirty fuels. Learn how to make cement and plastics and steel without spewing carbon dioxide. Replace gasoline cars with electric vehicles, public transportation, and walkable cities. Steward our land more wisely and eat fewer cows. It’s a daunting list: build, stop, learn, replace, steward. So many verbs, and none of them is “hope.” —
