The planet Earth is 4600 million years old. It is difficult for us to think about such an enormous length of time because it has little meaning for us. We can, however simplify idea to make it more understandable. We can compare the planet Earth to a person of forty-six years of age. Nothing is known about the first seven years of this person's life. Very little information exists about the middle period either. 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 arrived eight 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 Ace covered the Earth. Modern man has only been around for four hours. During the last hour man discovered agriculture. The Industrial revolution and the rise of large cities began just sixty seconds ago.
During that short time, modern man has made a rubbish of the Earth. In one minute, he has increased his numbers to terrible proportions and has caused the death of hundreds of species of animals. He has robbed and destroyed the planet in his search for fuels. Now he stands, like a violent spoilt child delighted at the speed of his rise to power, on the edge of the final mass destruction and of killing all the life which exists in the solar’s system.
