Don’t worry—I’m not going to pin my optimism on the hope that some miracle technology is going to save us. If it were up to technology to save us, it already would have. We have long possessed the technologies to live abundantly and sustainably on this planet, but we have used them to other ends. We could live in an earthly paradise using perfectly uncontroversial technologies: conservation, recycling, green design, solar energy, permaculture, biological wastewater treatment, bicycles, designing for reparability, durability, and reusability, and so on.3
