But ... before I go into that ... I want to confess my enormous ignorance of scientific facts. I have only just learned that there have been 5 mass extinctions in the earth's history:
(1) 439 million years ago: The 'Ordovician-Silurian Extinction', a drop in sea levels as glaciers formed then a rise as glaciers melted. Death to 60% of marine species types.
(2) 364 million years ago: The 'Late Devonian Extinction' was when another 57% of marine species types snuffed it, for reasons unknown.
(3) 251 million years ago: The 'Permian-Triassic Extinction' was the mother of all of catastrophes, wiping out 95% of all species including plants, insects and vertebrates. Some reckon a comet or asteroid hitting the earth caused it. Ouch.
(4) 199-214 million years ago: The 'End Triassic Extinction' happened when rivers of lava erupted and led to all sorts of land mass re-arrangements, including the formation of the Atlantic ocean. Global warming may have resulted, umpteen creatures perished.
(5) 65 million years ago: Quite recently as it turns out, the 'Cretaceous-Tertiary Extinction' killed off the dinosaurs and a whole slew of marine and land vertebrate species.
We are - today - currently - at this minute - right now - in the throes of Number (6): The 'Holocene Extinction'. Yep, mankind's use and abuse of our wondrous planet will result in the death of over half the planet's species within the next century. Heck, even dodos were still around until the 18th century.
So ... I'll get to the point ... I know we are witnessing a global catastrophe. And I also know the poverty and hardship that most of the world endures every agonising day makes my blessed life look like heaven with a cherry on top. So why do people like me still weep and worry over tiny problems like the mean whispering girl in Year 2? Why?????
I suspect it's for the same reason that telling a child "there are people starving in Africa, you know" isn't going to make him want to eat his peas.
