On this planet earth that reportedly has supported life for 3.6 billion years humans have been here for 200,000 of them. That turns out to be 0.004% of earth’s existence.
By the year 1804 humanoids multiplied their numbers to one billion.
One hundred and twenty-three years later these persistent persons doubled their presence to two billion in 1927.
Being real relentless momentum builders it would only take the Homo sapiens 99 years to increase their global presence to eight billion with an expansion rate of one billion every eleven years thereafter.
That’s a lot of toilets to flush!
Read the book Ten Billion by Stephen Emmott for a scientifically documented determination of our planets prospects and leave all hope behind…it is already too late.
Population summation: For all those out there who choose to disbelieve or pooh-pooh this scientific data; consider this; the human species has been on earth for 200,000 years. In that time his tail has atrophied…but not completely. Look at the present day man, and observe the tail-bone to discover the monkeys uncle…us.
Is there any dispute?
