What on Earth are we doing?

Scans of 'What on Earth are we doing?', a book published by Ladybird in 1976 that shows us how we can prevent further damage to Earth before it is too late. Snip from the book's forward: "What is the most dangerous animal in the world? A hungry tiger could kill a man in a few seconds and an angry elephant could soon trample him to death. Yet tigers and elephants are neither as dangerous as the animal you see when you look in a mirror. MAN is the greatest danger, not only to other human beings but to the world in which he lives in."
