"As Greta has told us so often: “Our house is on fire.” And I firmly believe that there are three things that have to align if we are going to douse the flames. First, we need the courage to dream of a different kind of future. To shake off the sense of inevitable apocalypse that has pervaded our culture. To give us a destination, a common goal, a picture of the world we are working towards.Greta Thunberg is one of the great truth-tellers of this or any time."
