DailyDirt: Who Needs Dinosaurs Anyway?
from the urls-we-dig-up dept
Jurassic World raked in over a billion bucks in less than 2 weeks by digitally re-creating some enormous (and sometimes fictional) dinosaurs. A few folks are actually working on re-animating prehistoric animals and other ancient organisms, but do we really need to bring these species back? Perhaps we should work on preventing an artificially-created extinction event of our own before we try to reverse the effects of the last one?
- An impact event that left a 110-mile-wide crater off the Yucatan coast of Mexico is most likely the cause of the mass extinction of the dinosaurs. That impact happened 66 million years ago, and it took a couple of million years for the ocean biosphere to recover its diversity afterwards. [url]
- A mass extinction occurring over 200 million years ago might have had a few contributing factors — perhaps bacteria (aka methanosarcina) produced a world-changing amount of methane? Volcanoes might have also been a contributing factor, too, but we may never really be certain what actually happened that many millions of years ago. [url]
- We’re headed for another mass extinction event, and the ‘Sixth Great Extinction’ is probably already underway. Species are dying off at a rate that’s over 100 times higher than ‘normal’ — are we only concerned when the next ‘great extinction’ also includes humans? [url]

The Gods of Yore
Humans have a responsibility of spreading earth based life to as many barren planets in this galaxy as we possibly can. Eventually all life forms die out and cease to exist, but so far at least some portion lived and spread again to establish a full ecosystem once more. Improve each world until it is capable of sustaining life for billions of years given the chance and we will have atoned for the species that will never again walk the earth.
Yeah, and who is one of the writers on that study that says we’re in a mass extinction? Why non other than Paul Erlich, Mr. “Every fucking prediction he makes is wrong!”
Re: Re:
The boy who cried wolf may be right this time. Just look at the amount of species with just a few hundred animals left. Even if they recover, a fully healthy population is difficult with low genetic diversity.
Look at the amount of species with only one habitat left. Single points of failure inevitably lead to disaster.
Elizabeth Kolbert’s “The Sixth Extinction” is a magnificent book, lyrically beautiful writing, and the profound message that, as a species, humans are The Extinction Machine, and have been since our earliest days. The chapter on how we came to have the concept of “extinction” is poetic. My highest recommendation. Do not miss this book.
