Planet Earth is 4,600 Million Years Old.
If we condense this inconceivable time-span into an understandable concept, we can liken Earth to a person of 46 years of age. Nothing is known about the first 7 years of this person’s life, and whilst only scattered information exists about the middle span, we know that only at the age 42 did the Earth begin to flower.
Dinosaurs and the great reptiles did not appear until one year ago, when the planet was 45. Mammals arrived only 8 months ago; in the middle of last week man-like apes evolved into ape-like men, and at the weekend the last ice age enveloped the Earth.
Modern man has been around for 4 hours. During the last hour man discovered agriculture. The industrial revolution began a minute ago. During those sixty seconds of biological time, Modern Man has made a rubbish tip of Paradise.
He has caused the extinction of 500 species of animals, ransacked the planet for fuels and now stands like a brutish infant, gloating over this meteoric rise to ascendancy on the brink of the final mass extinction and of effectively destroying this oasis of life in the solar system.
