It can reflect a deeply held concern about the damage that we are inflicting upon the natural world and what that means for future generations, not to mention all the other creatures with whom we share this planet.
Yes, it's true that about a third of species we've evaluated are threatened with extinction, and that we've killed about half of all our wildlife in the past forty years. But with all the gloomy predictions being thrown about, you may not know that the Sixth Mass Extinction is not a done deal.
The small, brown gliding frog will have peace and quiet for the remainder of his days in this shipping container. Mark will care for him until the last day when quietly, without any media hype, another species will silently disappear from our planet.
Top military experts and government institutions like the U.S. Department of Defense and National Intelligence Council warn that climate destabilization threatens our national security, yet global emissions just keep going up.
We are currently in the midst of what scientists consider the sixth mass extinction in planetary history, with between 150 and 200 species going extinct daily, a pace 1,000 times greater than the "natural" or "background" extinction rate.
There's a growing consensus among scientists that the earth is in the midst of its sixth mass extinction. The results of these calculations and models -- once they arrive in the popular media -- are increasingly positioned as scorecards, offering nature's "winners" and "losers."
The disruption of entire eco-systems is harmful to the people who depend upon them for their economic survival. Poaching in developing countries may temporarily enrich the poachers, but posterity is inevitably impoverished.
Unfortunately for us, earth has experienced at least five mass extinctions during the past 540 million years. Some scientists believe it may be as many as twenty. In other words, mass extinction events are not uncommon.
