22 “Conclusions” - for discussion (How) Can we reduce at required rate without economic crisis? (How) Can we reduce to required level without economic hardship? (How) Can the world’s people be made to accept rapid change? What other physical and thermodynamic limits are we close to? Why was energy not discussed in Copenhagen?
