It was once religion which threatened us with a last judgment at the end of days. It is now our tortured planet which predicts the arrival of such a day without any heavenly intervention.

It is a changing world because of the newcomers who keep arriving and who leave us behind. Trying to keep pace with them is doomed to inglorious failure, especially as the pace has quickened so much.
