Earth 'entering new age of geological time'

The Earth has entered a new age of geological time –
the epoch of new man, scientists claim. (http://www.telegraph.co.uk/earth/environment/geology/7528264/Earth-entering-new-age-of-geological-time.html)

Earth has entered a new age of geological time

Humans have wrought such vast and unprecedented changes on the planet that we may be ushering in a new period of geological history.

Through pollution, population growth, urbanisation, travel, mining and use of fossil fuels we have altered the planet in ways which will be felt for millions of years, experts believe.

It is feared that the damage mankind has inflicted will lead to the sixth largest mass extinction in Earth’s history with thousands of plants and animals being wiped out.

The new epoch, called the Anthropocene – meaning new man – would be the first period of geological time shaped by the action of a single species.

Although the term has been in informal use among scientists for more than a decade, it is now under consideration as an official term.

A new working group of experts has now been established to gather all the evidence which would support recognising it as the successor to the current Holocene epoch.

It will consider changes human activities have brought to Earth’s biodiversity and rock structure as well as the impact of factors including pollution and mineral extraction.

It is hoped that within three years, their case will be presented to the International Union of Geological Sciences, which would decide whether the transition to a new epoch has been made.

The theory has been proposed by a group of scientists, including Paul Crutzen, the Nobel Prize-winning atmospheric chemist, in the journal Environmental Science & Technology.

They conclude: “The Anthropocene represents a new phase in the history of both humankind and of the Earth, when natural forces and human forces became intertwined, so that the fate of one determines the fate of the other. Geologically, this is a remarkable episode in the history of this planet.”

Dr Jan Zalasiewicz, of the University of Leicester, co-author of the paper, added: “It is suggested that we are in the train of producing a catastrophic mass extinction to rival the five previous great losses of species and organisms in Earth’s geological past.”

Mass extictions... millions of years...

We certainly fucked something up, didn't we?

We certainly fucked something up, didn't we?

Before we start beating ourselves up, I think it's worth actually having a look and seeing if things could have turned out differently if we turn back the clock a few thousand years, as well as considering the very much worse things that have happened without human intervention at all.

Until very recently, we didn't know any better about looking after our environment - we raided nature's bounties and trashed innumerable beauty spots, but this did not matter since there were so few of us. The idea that humans (or any other species, for that matter) lived in "harmony" with the rest of nature is frankly rubbish.

Now at least, our relationship with resources and the environment demands reconsideration, due to the power granted to us by technology, as well as our huge numbers and voracious appetite for natural resources relative to previous eras of human history. The problem as I see it is that currently there is nowhere where the buck stops - it's all too easy to pass on problems to other people, through various ways fair and foul. In short, the human species is not accountable to itself.

This is a big problem for us if we wish to continue as an advanced technological civilisation, or if we wish to go higher, further, bigger and better than before in all spheres of human endeavour. Things need to change, and every sensible person agrees with this general statement, but the devil lies in the details.

But for the Earth? The Earth itself will be fine. Mass extinctions are nothing new. It's taken more knocks from giant space rocks than you've had hot dinners, has been covered in ice all the way to the equator, has had its atmosphere choked by massive outbursts of chronic volcanic activity, and generally speaking has not always been the pleasant blue-green-white sphere of life that some eco-worriers make out that it was before Man and his Evil Technology caused the Fall.

Furthermore, does it really actually matter if some of the changes we've (almost entirely inadvertantly) caused to the planet could be detectable for millions of years? We'll either be long extinct, or more than advanced enough to fix anything we percieve to be a problem, if we're still even in the vicinity.

So my conclusion? Bring on the Anthropocene. Let's make this a geological age worthy of stamping our name on it!
