That humans are having major impacts on the planet is now quite clear, and some of those impacts may be evident millions of years from now. Are we a cancer on the biosphere, a plague? Would it be better if we had remained blissfully in the stone age? Our angst about such matters may be no more helpful to building sustainable systems than is white guilt in forging racial justice. Guilt about environmental destruction won’t help build a sustainable society, but active love might, the kind of love we have for our teenagers when they’re especially annoying. JD somehow relates all of this to romantic relationships, beautiful sunsets, and Joni Mitchell.
