The (Dangerous?) Allure of Geo-engineering

To the traveler, it may appear that a given stretch of forest or grassland or high steppe exists just as it has for thousands of years, untouched and in a pristine state, sculpted only by the hand of mother nature. Chances are, the traveler is dead wrong.
Erle Ellis, an Associate Professor at the University of Maryland's Department of Geography and Environmental Systems, wants you to understand this. In fact, he argues that understanding this is absolutely essential to understanding man's place on what so many like to lovingly refer to as "spaceship earth".
Ellis believes humans have been "interfering" in the development of the Earth and its biosphere for far longer than we give ourselves credit for. The danger of these prelapsarian narratives, as we at Breakthrough have argued in the past, is that we fail to see our own proper place in the greater scheme of world development.
In his latest op-ed in Wired magazine, Ellis argues bluntly that Nature -- and the idea that there exists a place untouched by Man, the John Muir wilderness where the River Runs Through It but little else -- is long gone.
Nature is gone. It was gone before you were born, before your parents were born, before the pilgrims arrived, before the pyramids were built. You are living on a used planet.
If this bothers you, get over it. We now live in the Anthropocene -- a geological epoch in which Earth's atmosphere, lithosphere and biosphere are shaped primarily by human forces.
The species that humans eliminated were keystone species whose lifestyles, like those of elephants in Africa today, tended to profoundly shape and sustain ecosystem form and function by their feeding habits. ...
And what of the wild forests of Amazonia and North America that we think of as pristine? Think again. The second line of evidence -- from archaeology, paleo-ecology and even epidemiology -- that humans lived all over these lands is growing. Man burned down the forests millenniums before Columbus, first to enhance hunting for the wild species attracted to the regrowth, and later for agriculture....
So there you have it: Ours is a used planet. Thanks to us, Earth has become warmer, less forested and less biodiverse for millenniums.
So what now? First of all, we've got to stop trying to save the planet. For better or for worse, nature has long been what we have made it, and what we will make it.
And it's time for a "postnatural" environmentalism. Postnaturalism is not about recycling your garbage, it is about making something good out of grandpa's garbage and leaving the very best garbage for your grandchildren. Postnaturalism means loving and embracing our human nature, the nature we have created to feed ourselves, the nature we live in. What good is environmentalism if it makes you depressed about the future?
This is about recognizing that our farms, and even our backyards and cities, are the most important wildlife refuges in the world and should be managed as such. We can keep people out of places we want to think of as wild, but these places will still be changing because of global warming and the alien species we introduce without even trying.
If we want these places to look like they did before us, we will have to constantly recreate them. It will be a huge job for us humans to keep nature "wild." ...
Don't like it? Stop trashing it!
Use renewable energy. Clean it up. Repair it. Get to work. There is plenty more mileage left in this spaceship Earth. Think about that while enjoying a trip to your local zoo or arboretum -- the most biodiverse places that ever existed on Earth.

I agree, R. Humans are a part of the greater ecosystem and any analysis that assumes otherwise is basing its results on a flawed premise. What's interesting to me is the psychological effect of understanding specifically just how we are changing things so we can tailor the result to the positive. ... Seems to me a rewrite of a few textbooks is in order.

This piece reminds me of the writings of Jacob Bronowski and Kraft Ericke. Both argued that humans shaping nature is the ultimate adaptation to nature and is itself natural. I have always been suspicious of the false dichotomy of human vs nature.
