by Dr Frank Fraser Darling
4: Global changes: actual and possible
Belching factory chimneys, sewer-like rivers, and mushroom towns were once equated with progress. The crude dereliction has gone, but more sophisticated problems are taking its place. Frightening overpopulation and subtle forms of pollution face us Spectator violence, Black Power, and student unrest are all implosive signs of an over-populated planet. We are no longer sure of ourselves.
Have we enough time left, asks Dr Fraser Darling , to reverse the trends before we are overtaken by the horrors of famine, pestilence, irreversible pollution of air and water, or war.
