Necessary steps will include phasing out fossil-fuel use within a decade; directing a large share of our energy, materials, and labor toward building a renewable energy sector and a high speed rail network; restoring our forests, grasslands, and croplands so that we are putting more carbon into the soil and less into the atmosphere; deeply cutting meat and dairy consumption; and converting a large portion of the U.S. military into a kind of climate mobilization force.
All of that will require a national reallocation of resources among sectors of production, one that diverts a significant share of a necessarily declining resource budget into building green infrastructure and leaves the consumer economy a lot less to work with.
