Kaiser, I remind you that in science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations. As for the ability to predict tippinig points in Nature or otherwise, some exciting work appears to be ongoing utilizing generic markers that are equally valid for all complex systems as they approach tipping points.

Up to 50 percent of all individual ani- mals have been lost in recent decades. Two-fifths of the 177 mammal species sur- veyed lost more than 80 percent of their range or geographic distribution between 1900 and 2016. The release of this study coincides with news that the world’s population has reached an all-time high of 7.6 billion. In Asia, the world’s most populous continent, three-fourths of the mammal species sur- veyed have lost 80 percent of their range in the last century or so. The fact that animal and human popu- lations are moving in opposite directions

There is no terrestrial ecologist on the planet who view this topic as fake news, none that are even vacillating on the question of accelerated extinctions caused by humans being a real time reality.
