Vandalising Home

Somewhere in the oeuvre of Hans Blumenberg's Metaphorology he stated that humans are vandalising God's creation having usurped the power of sole owners of the world and the rest of the universe.

In more popular circles the same has finally been mentioned by a Pope: "If we destroy Creation, Creation will destroy us."

"We are sawing off the limb that we are sitting on." BBC

The lust to eradicate life from our only common home is a self destructive suicidal mental condition.

For some time we have been working hard at making the sixth mass extinction possible at ever greater speed:

Accelerated modern human–induced species losses: Entering the sixth mass extinction

"The oft-repeated claim that Earth’s biota is entering a sixth “mass extinction” depends on clearly demonstrating that current extinction rates are far above the “background” rates prevailing in the five previous mass extinctions. Earlier estimates of extinction rates have been criticized for using assumptions that might overestimate the severity of the extinction crisis. We assess, using extremely conservative assumptions, whether human activities are causing a mass extinction. First, we use a recent estimate of a background rate of 2 mammal extinctions per 10,000 species per 100 years (that is, 2 E/MSY), which is twice as high as widely used previous estimates. We then compare this rate with the current rate of mammal and vertebrate extinctions. The latter is conservatively low because listing a species as extinct requires meeting stringent criteria. Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 114 times higher than the background rate. Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear. These estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way. Averting a dramatic decay of biodiversity and the subsequent loss of ecosystem services is still possible through intensified conservation efforts, but that window of opportunity is rapidly closing."
