The sperm of all 18-year-olds should be frozen for use in later life because of the risks attached with being an older father, Dr Kevin Smith, from Abertay University in Dundee, says. He also adds, ‘ sperm-banking on the NHS should “become the norm”. He is a bioethicist.
Sperm becomes more prone to errors with age, increasing the risk of autism, schizophrenia and other disorders. The British Fertility Society also agrees since such a move would “provide a very artificial approach to procreation”.
Progress of men has made acquisition of things a priority than in number of progeny. There is nothing of a gene push since we have become self indulgent and children of impulses and self gratification. There is no such thing as an Alexander the Great having his four generals to carry on with his grand Hellenism, an idea that changed the course of the world. What can you expect from Tom, Dick and Harry whose only aim in life is Instant gratification?
Men are having children later – the average age of fatherhood in England and Wales has increased from 31 in the early 1990s to 33 now. This must send alarm bells ringing. We are on the edge of a live crater and the volcano may snuff out human race like so many mass extinctions in the past.
Since the last great mass extinction of the dinosaurs 66 million years ago, life on Earth is entering the greatest mass extinction according to a major new study – and humans may be among the casualties. What does that entail? It would leave a huge hole in the world’s ecosystems,- and lemurs, aye-aye, jumping rats on the island of Madagascar are on the precipice of extinction, and so many others. There have been five major mass extinctions in Earth’s history. Scientists predict a Sixth. If we were to compare the time frame of the other five it would not be outside the realm of probability.
So let’s be pessimistic, and assume the apocalypse is going to happen. What does Earth look like afterwards?
The greatest crisis in history
The Permian-Triassic boundary (251m years ago) saw the greatest crisis in Earth’s history, when at least 90% of the species including insects suffered huge losses – the only mass extinction in their long history.
This was attributed to the effects of huge volcanic outpourings of lava and associated greenhouse gases, in what is now northern Russia. This lead to global warming, ocean acidification and acid rain, marine oxygen depletion and poisoning by toxic metals such as mercury. Imagine today’s gloomiest climate predictions, but cranked up a few notches.
The few species that survived gave rise to all life thereafter and there has not been such a profound restructuring of ecosystems since, perhaps because this “survival of the fittest” rendered their descendants more tolerant to global change.
What chance man has since he never branched off into so many sub species or genera?
Man even when the volcano goes out into showers shall have a selfie to make . Only trouble is he may have none to share it with.(ack: The Conversation- How life on Earth recovers after a devastating mass extinction by David Bond-univ. of Hull/ 24 June, 2015;)
Even on the mouth of an angry volcano my advice for man would be, ‘keep your cool man. Plenty of time to go up in smoke.’
