The giant fishes, trilobites, sponges and brachiopods also declined dramatically, while organisms on land had much higher survival rates.

But but but...without the Devonian extinctions, archosaurs wouldn't have developed. Save the dinosaurs!!

“Invasive Species Stop New Life”

They’re called liberals.

Analogies to Muzzie demographic infiltration of England, Europe, and (attempted) the United States and (apparently checked at the moment) Australia.

H1-Bs, "diversity," and "outsourcing" have stymied a LOT of the creative, "can-do" mindset of the U.S.

Our businesses are concentrating on stealing mindshare rather than on creating fundamentally new opportunities.

NO cheers, unfortunately.

Around here the best example of an invasive species changing things is purple loosestrife. It crowds out the cattails and there are a lot fewer redwing blackbirds around as a result. The plant also clogs waterways and affects things that way as well.

The birds aren’t on the edge of extinction or anything but the numbers have definitely fallen since I was a kid.

Based on what? Compared to what?

“In addition, the modern extinction rate exceeds the rate of ancient extinction events, including the event that wiped out the dinosaurs 65 million years ago.”

You mean the “ancient extinction events” about which there’s no agreement as to what they even were (asteroid impact, communicable disease, etc.)? Since extinction rates are determined over milleninia, how is it possible to accurately compare “modern extinction rates” to the rate of “ancient extinction events” (for which only partial, questionable evidence exists)?

More “scientific” blather by “scientists” shooting in the dark, hoping to hit a grant-money pinata.

Oh we have the creative mindset. One only needs to look at the engineering genius that drives our military industrial complex and our entertainment (entertainment delivery and production) industries to see that we have the MINDPOWER to make it big.

What we are lacking is the industrial base to drive it forward.

We will never, ever, ever be able to compete with competent labor that produces high quality products at $4 an hour.

It is this lack of industrial power that is hurting us. And it will not come back. Ever.

This is why we use our homes as ATMs and run up credit card debt. We are doing nothing but moving money around in the service economy.

The only people producing anything these days are the folks that mint silver and gold coin.

I think that boilerplate is de rigueur.

“I think that boilerplate is de rigueur.”

Agreed...just about everything in that “article” was boilerplate.
