It is difficult for us to think about such an enormous length of time becauseit has little meaning for us. We can. however, simplify the idea to make it more understandable. We can compare the planetEarth to a person of forty-sfx years of age. Nothing is known about the first seven years of this person's life. Very little information exists about the middle periodeither. It was only at the age of forty-two that the Earth began to flower. Dinosaurs and great reptiles did not appear until one year ago. when the planet was forty-five. Mammals only arrivedeight months ago. in the middle of last week, man-like apes became ape-like men and began to communicate with each other.Last weekend, the Ice Age covered the Earth. During that short time, modern man has made a rubbish tip of the Earth. In one minute, he has increased his numbersto terrible proportions, and has caused the death of hundreds of species of animals. He has robbed and destroyed the planet insearch for fuels. Now he stands like a violent, spoilt child, delighted at the speed of his rise to power, on the edge of the finalmass destruction and of killing all the life which exists in the solar system.
