With the help of science, we’ve come to understand our impact on the planet that is our home. With each item we produce, building we construct, forest we cut down, acre we plow, and journey we make — enabled by resources we derive from our planet’s prehistoric past — we do small amounts of harm to the fragile balance of nature that sustains life. As we’ve replicated our capabilities and developed our ability to scale, those tiny harms have multiplied to the point that the cumulative damage now threatens our planetary life-support system.
Efforts to address this situation have so far consisted of denial, modest efficiency improvements, recycling, and, in some cases, the substitution of products less harmful than their predecessors. But these well-intentioned actions are not nearly enough to stop, let alone reverse, the effects of global climate change. What we need is a way to rewind the ecological
