Food for Thinkers: Eating Rocks

Friends of the Pleistocene examine contemporary foodscapes for traces of geologic time, from seed vaults to radioactive salt.

Friends of the Pleistocene is a blog with an unusual, and unusually interesting, mission: to "create contexts and speculative tools for humans to recalibrate their sense of place within the geologic timescale." Reshaping cognitive pathways to grasp the multi-billion year timespans of geologic history is not just an idle thought experiment, according to Jamie Kruse and Elizabeth Ellsworth, the artists behind Friends of the Pleistocene. As they explained in a recent article on Urban Omnibus:

Modern life and deep geologic time are profoundly embedded within one another, with great consequence for both the present and the future. Humans are not only intimately living with—and rapidly using up—geologic material that took scores of millions of years to create, we are also laying down a new and utterly unique stratum on the earth. It's made up of human-made materials (including waste), and it will remain as one of earth's geologic layers long after our species is gone.


Their investigations into the places where contemporary life and the geologic converge have led them on field trips to New York City's largest glacial pothole (it's in Inwood Hill Park) and in search of the source of the 10 million-year-old road salt we sprinkle on our wintry streets.
But for Food for Thinkers week, naturally, they looked for ways in which "today's food production, consumption, and even protection are taking up and sometimes eating up the geologic."

Their guide to "sightings" of geologic time within today's foodscapes include a look at the idea of terroir, as well as an overview of the flavors of deep time and Anthropocene-era radioactivity embedded in cooking salt. They also report on the phenomenon of seed vaults (such as the one at Svalbard, pictured above), in which geology has become "the front line of food's future."

Geologic forces play a main role in the design and function of the vault. The site at Spitsbergen was considered ideal because of its lack of tectonic activity and its permafrost, which will aid preservation. According to Wikipedia, the location, 130 metres (430 ft) above sea level, will ensure that the site remains dry even if the icecaps melt. Locally mined coal provides power for refrigeration units that further cool the seeds to the internationally recommended standard −18 °C (0 °F). The permafrost surrounding the facility will help maintain the low temperature of the seeds if the electricity supply should fail.

Food for Thinkers is a week-long, distributed, online conversation looking at food writing from as wide and unusual a variety of perspectives as possible. Between January 18 and January 23, 2011, more than 40 food and non-food writers will respond to a question posed by GOOD's newly-launched Food hub: What does—or could, or even should—it mean to write about food today?

Follow the conversation all week here at GOOD, join in the comments, and use the Twitter hashtag #foodforthinkers to keep up to date.

A study out of Belgium found that smart people are much less likely to be bigoted. The same study also found that people who are bigoted are more likely to overestimate their own intelligence.

A horrifying story out of Germany is a perfect example of this truth on full display: an anti-Semite was so dumb the was unable to open a door at the temple he tried to attack.

On Wednesday, October 9, congregants gathered at a synagogue in Humboldtstrasse, Germany for a Yom Kippur service, and an anti-Semite armed with explosives and carrying a rifle attempted to barge in through the door.

The old saying goes something like, "Possessions don't make you happy." A more dire version is, "What you own, ends up owning you."

Are these old adages true or just the empty words of ancient party-poopers challenging you not to buy an iPhone 11? According to a new study of 968 young adults by the University of Arizona, being materialistic only brings us misery.

The study examined how engaging in pro-environmental behaviors affects the well-being of millenials. The study found two ways in which they modify their behaviors to help the environment: they either reduce what they consume or purchase green items.

One of the biggest obstacles to getting assault weapons banned in the United States is the amount of money they generate.

There were around 10 million guns manufactured in the U.S. in 2016 of which around 2 million were semiautomatic, assault-style weapons. According to the National Shooting Sports Foundation, the firearms industry's trade association, the U.S. industry's total economic impact in 2016 alone was $51 billion.

In 2016, the NRA gave over $50 million to buy support from lawmakers. When one considers the tens of millions of dollars spent on commerce and corruption, it's no wonder gun control advocates have an uphill battle.

That, of course, assumes that money can control just about anyone in the equation. However, there are a few brave souls who actually value human life over profit.

Trees give us a unique glimpse into our past. An examination of tree rings can show us what the climate was like in a given year. Was it a wet winter? Were there hurricanes in the summer? Did a forest fire ravage the area?

An ancient tree in New Zealand is the first to provide evidence of the near reversal of the Earth's magnetic field over 41,000 years ago.

Over the past 83 million years there have been 183 magnetic pole reversals, a process that takes about 7,000 years to complete.

The final episode of "The Sopranos" made a lot of people angry because it ends with mob boss Tony Soprano and his family eating at an ice cream parlor while "Don't Stop Believin'" by Journey plays in the background … and then, suddenly, the screen turns black.

Some thought the ending was a dirty trick, while others saw it as a stroke of brilliance. A popular theory is that Tony gets shot, but doesn't know it because, as his brother-in-law Bobby Baccala said, "You probably don't even hear it when it happens, right?"

So the show gives us all an idea of what it's like to die. We're here and then we're not.
