The following is reported by The Guardian:
Scientists have found evidence that the disappearance of wildlife is occurring at a rapidly increasing rate – renewing fears of a human prompted ‘sixth mass extinction’ (named the Anthropocene Extinction) which will endanger our survival. When researchers looked at 29,400 terrestrial vertebrate species for which population data is available, they found that of 543 extinctions that occurred since 1901, 173 took place between 2001 and 2014. The trajectory is set to continue climbing. 515 species are are now classed ‘critically endangered’ by the IUNC; that is with populations fewer that 1,000. Examples include the Sumatran rhino and the Hainan gibbon.
Here I digress from the article:
So much of this loss is as the result of human activity, for example an increasing population forcing towns and cities to expand into nature’s habitat. The forcing together of wild animals, especially in meat markets of eastern Asia, often in appalling conditions, means that disease and viruses are more easily transmitted between species.
This was the case in Wuhan, when COVID-19, it is thought, passed from bats – which have a natural immunity – to pangolins. From here it jumped to humans. It appears not to jump the other way as the virus seeks a healthy and hardier species to invade; it is not in its interest that the host should die. The fear now is that it will pass to hitherto unaffected regions of the world, higher primates and, who knows, elephants, dolphins and whales……the list goes on!
In spite of fears of a second peak and subsequent peaks in COVID-19 cases, the UK and other governments have to balance the risk of relaxing the recent punitive measures against a severe and continuing downturn in their economies. This has the potential to prove fatal to human existence on earth. A vaccine has not yet been developed (NB – at the time of writing). The common cold, another form of coronavirus, is still endemic. Could cases worldwide exceed those of the bubonic plague of 1347 killing an estimated 475 million people, 20% of the, then, world’s population and taking some 200 years to recover? Well, this may or may not happen; the current crisis could, if we are lucky (!), prove to be a mere stutter towards the inevitable extinction of life as we know it.
