Forgive me, haven't read the article yet, but I will!
You'll be hard pressed to find many folks that like trees more than I do, but the fact is, they're losing!
They've been losing for about 5 million years... Thanks grass!
This won't change, were on the cusp of one of the fastest changes our earth has seen, we are a HUGE contributing factor ourselves, don't get me wrong... But change is enevitable.
If I understand correctly, we are actually in an ice age as we speak!
They work in cycles, 100000 years of frigid cold, 10000 years or realities warmth, we're currently coming to the end of a period of relative warmth. At the end of the warm cycles, the ice ages either return to frigid, or the ice age breaks.
Personally I think it's safe to say that humans have insured that the ice age is over!
There's good news (not for us of course!)though!
It really doesn't matter!
Life will persist, just as it has for all these eons!
It's all very natural, just the same as a birds nest is natural, so is everything we do!
Fret for your children ( and mine) if you like( I do), and all the species that will perish, just know that the end of our miserable existence here won't mean much for Mother Earth, she's lived through much harsher times than we can dish out!
Grass alone has lead to the extinction of tens of thousands of species in the past 5 million years, it's also given rise to many as well.
