The Hunt for Life Beyond Earth, by Michael D. Lemonick, photographs by Mark Thiessen

The Hunt for Life Beyond Earth is pretty much just like it says:  it’s about scientists’ attempts to find life on other planets.  Needless to say, Mars is one of the planets they are considering as home for this extraterrestrial life, but Mars is too close.  Rocks travel back and forth between Earth and Mars periodically.  As a result,  the discovery of life on Mars would not prove that said life developed there.  It could be terrestrial life that made the trip between the two planets.

Based on the premise that life should be develop in places with liquid water, we are also looking at two of Jupiter’s moon Europa and Saturn’s moon Enceladus, as possible sites of life.  Saturn’s moon Titan also has liquid, but that liquid is methane and not water.  As a result, scientists who are looking for life haven’t ruled Titan out, but they are uncertain what kind of life would develop in liquid methane.

Then there is the possibility of life beyond our solar system.  In 1961, an astronomer named Frank Drake created what is now known as the Drake Equation, which is an equation to calculate how many extrasolar civilizations we should be able to contact.  The equation included the number of sunlike stars in our galaxy, the number of those stars that had planetary systems, the number of planetary systems that have planets capable of sustaining life, the number of planets that actually do develop life, the number of those whose residents develop intelligence, and the number of those who develop radio signals that we could detect.  We are just now starting to be able to apply numbers to these variables.

As someone who has read and watched entirely too much science fiction for her own good, I think that the Drake Equation may understate the number of planets that we might be able to communicate with.  What if a society jumped right to television?  Or used some other form of radiation that we cannot yet detect to communicate?  Or evolved while orbiting a sun completely different from ours?  The Drake Equation might be a good estimate, but there are no guarantees that it is the only way for life to develop.  It’s just the way that our life developed.

The Next Breadbasket, by Joel K. Bourne, Jr., photographs by Robin Hammond

The Next Breadbasket is another installment in the Future of Food series.  For this installment, we travel to Africa to watch the various ways that the fertile land, and those who work it, are being both used and exploited by agribusiness.  In too many African countries, the government allows the agribusiness entities to run people, some of whom have been farming this land for generations, off of their land.  Bourne names names, both of the companies that have treated the indigenous people well and those who have treated the people poorly.

So far, two of the ones that Bourne seems to support are a company called African Century Agriculture which uses an “outgrower” model, in which African Century provides soybeans, weeding, and training in conservation agriculture to small farmers. The farmers then sell the soybeans that they grow back to African Century, which deducts the costs of their services from the payment.  This way, the small farmers get to keep their land and also get education in the latest agricultural techniques.

Another company that Bourne seems to me to think well of is Bananalandia, the largest banana farm in Mozambique.  The owner of Bananalandia, Dries Gouws, pays his workers at least 110% of the Mozambican minimum wage and he also has done things to improve the lives of the people in the surrounding villages, including paving roads, providing electricity, building a school, and making improvements to the sewage system.  I know well that 110% of minimum wage is in no way going to raise these people out of poverty, but I feel that the other improvements in the quality of life that Gouws has made are not insignificant either.

The Wells of Memory, by Paul Salopek, photographs by John Stanmeyer

In The Wells of Memory, the second installment of Salopek’s Out of Eden Walk series, Salopek is walking up the western coast of Saudi Arabia, through an area known as the Hejaz.  The Hejaz was added to what is now Saudi Arabia in 1925. Both Mecca and Medina are in the Hejaz, so until the era of airplane flight, most of the pilgrims coming from around the world had to pass through the Hejaz. Jeddah, also in the Hejaz is the burial place of Eve, according to legends.

Salopek focuses in part on the wells that are spread, a day’s walk apart, through the Hejaz.  The wells date back to the Caliphate of Caliph Umar in 638.  There were also guesthouses, forts, and hospitals along the route, courtesy fo the Caliph.  Today, in addition to the ancient wells, there are asbila, outdoor electric water coolers along the route these days.

Salopek is one of the first, if not the first, Westerner to travel this route in close to a century, but this is the route taken by other Westerners in the past, including Lawrence of Arabia.

As with nearly all National Geographic stories, The Wells of Memory is punctuated by photographs.  However, some of the photographs in this story were taken with a smartphone and then edited to look like vintage, sepia-toned photographs with an app called Hipstamatic.  Stanmeyer chose this approach to reflect his feeling that he “had one foot in the present, and the other had stepped back a hundred years.”

Big Fish, by Jennifer S. Holland, photographs by David Doubilet and Jennifer Hayes

For the past 25 years, the Altantic goliath grouper has been a protected species.  Once sport fishermen would catch them by the dozen, but goliath groupers are long-lived and reproduce slowly.  This meant that the fish were not able to replace their numbers as quickly as they were being harvested.  This resulted in the species being granted legal protection as an endangered species.

Now, some fishermen believe that their numbers have rebounded enough that it should be safe to start catching them again.  In part they want the trophies, but these fishermen also believe that the goliath grouper is eating fish that the fishermen should legally be able to catch, thus reducing the numbers of legal fish even farther.

Holland seems unswayed by these fisherman’s arguments.  She has spoken with scientists who are studying goliath grouper and who believe that the population is still too low.  Goliath groupers tend to stick to one area, and until they start to overpopulate that area, they will not spread elsewhere in their range.  Additionally, according to Holland, there are a number of studies (she doesn’t tell us which ones) that show that there is not much overlap between the targets of the fishermen and those of the goliath grouper.  If the fishermen are finding it difficult to find fish to catch, it is not the fault of the goliath grouper.

Additionally, just because their numbers are rebounding now does not mean that this will continue indefinitely.  Goliath grouper juveniles live in mangrove swamps, and the mangroves in their home range are being decimated.  To make matters worse, due to mercury levels, goliath grouper are coming down with lesions in their livers.  This may also have an impact on their population numbers in the long term.  It also makes goliath grouper unsafe to eat, so fishermen who catch them would need to throw them back, or use them only for trophy purposes, which would be wasteful.

Empire of Rock, by McKenzie Funk, photographs by Carsten Peter

Alas, Empire of Rock has nothing to do with popular music.  It is, in fact, about the karst caves underneath Guizhou, China.  This part of China was once covered by a sea.  Over the centuries, the mollusks left their shells behind, which compressed into a  limestone formation known as karst.  Karst is limestone which is punctured by holes.  Water seeps down into the holes, which wears the holes away until they join together and eventually form caves.  This area is relatively unique in that this process has taken place over so many centuries that there are entire mountains of karst on the surface.  Have you ever seen photographs or Chinese paintings of large, steep stone mountains, usually surrounded by mist?  Those are karst mountains.

Funk accompanied a group of scientists and cavers who were attempting to measure the volume of one of the largest cave chambers in the world, the Hong Meigui chamber.  Though Funk’s eyes we watch them descend into the chamber and see their laser scanners, which Funk tells us is about the same size as a human head, measure the volume of the cave.  Funk and her hosts also visit other caves and karst formations in the area.

“Hong Meigui,” by the way, is the word that inspired me make my last post, on my experiences with foreign language.  “Hong Meigui,” depending on the tones, can mean “red rose.”  And I suspect that may be the meaning here, since there is a caving organization called the Hong Meigui Cave Exploration Society and the characters for the name of that group are the “hong,” “mei,” and “gui” of “red rose.”  Another chamber mentioned is the Miao Room, and my first instinct was that the “miao” in question is “temple,” but, when looking at a list of other “miao”s, it could also be the “miao” that means “infinity,” or any of a number of other Mandarin words that can be transliterated as “miao.”  I just don’t know.  To make things more frustrating, Funk does imply one translation when he tells us that the Yanzi cave is named for the swallows that live in the walls.

Two months after the cover date on this magazine, in September 2014, the title of the largest cave in the world was granted to the Miao Room.

2/3/2019 On or around November 28, 2018, I realized that I need to start monetizing this blog. To that end, I’m starting to put what I call Gratuitous Amazon Links into my posts. As of January 12, 2019, I’m going back to add GALs to my older posts. If I can’t find anything exactly on-topic to the post, I’m choosing from among the highest-rated items on the same topic as the post. For example, for a post on a park, I’ll search Amazon for books on parks and choose one of the ones with the highest reader ratings. Here is the GAL for this post:

National Geographic Animal Encyclopedia: 2,500 Animals with Photos, Maps, and More! by Lucy Spelman (Author)

National Geographic August 2014

Before Stonehenge, by Roff Smith, photographs by Jim Richardson

Before Stonehenge is the cover story, and, like other cover stories, the blurb on the cover doesn’t even begin to, well, cover it. The blurb says, “The First Stonehenge: Britain’s Master Builders” and, well, this article does discuss the Stones of Stenness, which is likely to be the oldest stone circle in Britain. But the article is so much more than just that one monument.

In Before Stonehenge, we see Skara Brae, for example.  Skara Brae is an entire neolithic village on a headland known as the Ness of Brae.  The homes had furniture and built-in storage units that would likely have been a lovely selling point if there were any such thing as a stone-age real estate market.

When you look at Orkney, an archipelago to the north of Scotland, on a map, it seems like it should be cold and inhospitable.  It is roughly parallel with the Gulf of Alaska, after all.  And yet, the average low temperature for Orkney for February (the average coldest month) is 35.1 degrees Fahrenheit/1.7 degrees Celsius.  That’s 15 degrees Fahrenheit warmer than the average low temperature in February in Chicago.  Credit for this mild climate goes to the Gulf Stream.  Thanks to the Gulf Stream, the islands had a bustling agricultural economy that allowed the residents the freedom to express themselves artistically, as well.  So far, more than 650 works of art have been discovered.

And Orkney was not nearly as remote as its location would have you believe.  It was, in the words of Caroline Wickham-Jones of the University of Aberdeen, “an important maritime hub, a place that was on the way to everywhere.”  And the article contains a map that shows the extent of the settlements of Orkney during the Neolithic.  The current estimates are that there were more than 10,000 people living in the Orkney islands during the Neolithic.

Best of all, only around 10% of the Ness has been excavated, which means that there are certainly more treasures to be discovered on the Ness of Brae and, perhaps, all over the Orkney Islands.

Gombe Family Album, by David Quammen, photographs by Anup Shah and Fiona Rogers

On April 3, 2014, Jane Goodall turned 80 years old.  In recognition of the occasion, David Quammen interviewed  Goodall.

Goodall recalls being told that she had done her work  “wrong” in the minds of the establishment in animal behavior.  When Goodall went to Cambridge to get her Ph.D. in ethology, her professors didn’t want to hear about the personalities of the chimpanzees. They wanted her to be able to find patterns in their behaviors.

From here, the conversation moves on to discussions of the personalities, and personal histories, of some of the chimpanzees she got to know at the Gombe Stream Research Center in Tanzania.

The article is illustrated with a photo of Goodall in the 1960s holding hands with a chimpanzee named Figan.  This photo was  taken by Hugo Van Lawick.  There are also beautiful portraits  of some of the chimpanzees she worked with:  Frodo, Samwise, Gaia, Sparrow, Gremlin, Gizmo, and Nasa.

The New Face of Hunger, by Tracie McMillan, photographs by Kitra Cahana, Stephanie Sinclair, and Amy Toensing

The New Face of Hunger, this issue’s installment of the Future of Food series, is based in the United States.  The article focuses on the millions of Americans, most of whom are working full-time, who are facing food insecurity.  You are likely familiar with the term “food insecurity.”  This is the term which, since 2006, has replaced “hunger” in order to reflect the new reality of hunger in the United States.  In past generations, people either had plenty of food or were pretty consistently short on food.  In the current era, however, many people have plenty of calories but are short on nutrition, which can lead these people to become obese.  Additionally, these people cannot aquire  even the high-calorie low-nutrient-dense foods that they have the time and/or money predictably, which leads them to have this new term, rather than calling them “hungry.”

In The New Face of Hunger, we visit food-insecure families in Iowa, Texas, and New York. We talk about the food insecure and food deserts.  Many people live in what is known as a food desert.  A food desert, according to the United States Department of Agriculture, has to meet two criteria:

  1. They qualify as “low-income communities“, based on having: a) a poverty rate of 20 percent or greater, OR b) a median family income at or below 80 percent of the area median family income; AND
  2. They qualify as “low-access communities“, based on the determination that at least 500 persons and/or at least 33% of the census tract’s population live more than one mile from a supermarket or large grocery store (10 miles, in the case of non-metropolitan census tracts).

The article also discusses the role of subsidies in hunger.  The top five most highly subsidized crops between 1995 and 2012, were corn, cotton, wheat, soybeans, and rice.  The four of these that are edible are high-energy (which is the fancy way of saying that they have lots of calories) but are not so full of nutrients.  Fruits and vegetables, to the extent that they are subsidized, are subsidized at a much lower rate, which keeps those crops much more expensive (particularly on a per-calorie basis) than crops such as corn and wheat.  On the other hand, however, the subsidies that do exist help to keep the high-calorie foods that are highly subsidized more affordable to low-income people.  Without those subsidies, perhaps rather than food insecure people, we’d have a much higher rate of the truly undernourished poor in the United States.

While noodling around with the Food Access Research Atlas on the USDA website, I found evidence that apparently the USDA does not consider a Walmart Supercenter to be a supermarket, despite the fact that a Supercenter is about 1/3 groceries.  A new Supercenter opened in San Antonio last year and the area right next to it is shown as being a low-income area more than a mile from a supermarket or large grocery store.  Upon further looking at the map, I think that perhaps that’s just a side effect of the size of the census tract, because I just realized that there is an indisputable “supermarket or large grocery store” just about a mile from that Supercenter, also bordering on that same census tract.  Maybe, since the tract is so large, since the people on the far end are more than a mile from a store, all of them are considered to be in a food desert.

Franz Josef Land: The Meaning of North, by David Quammen, photographs by Cory Richards

In Franz Josef Land: The Meaning of North, Quammen and Richards accompany a scientific expedition to Franz Josef Land, an archipelago in the far north of Russia to determine why the ice is melting, how extensive the melting will be, and what the ecological consequences of the melting will be.  Their group of 40 people include experts and students in a variety of disciplines including but not limited to botany, microbiology, ichthyology, and ornithology.

We meet a number of the people on the expedition including Michael Fay, the botanist, who walked across the forests of Central Africa.  We also meet Enric Sala, whom we will see again in the September, 2014 article on the Southern Line Islands.

One of the things that is emphasized is how heavily armed the guards that accompany the expedition are.  I was wondering if the expedition was facing some kind of danger from humans.  I’m not sure who would be a threat that far north, maybe some kind of insurrectionists would be hanging out there, but it turns out that the guns are to protect them from polar bears.  And the author does have one close call.  Fortunately the situation is resoilved without violence,  There is a  lovely closeup photograph of a polar bear (not taken during that close call but with a remote camera).  The caption states that the remote camera was later chewed up by the polar bear.

And, of course, no conclusions can be made yet about the fate of the ice of Franz Josef Land.  All the scientists can do is collect data, watch trends, and see what conclusions they can draw from those down the line.

The Hidden World of the Great War, by Evan Hadingham, photographs by Jeffrey Gusky

The Hidden World of the Great War is about the reality of the trench warfare of World War I.  The soldiers did not just stand in trenches, they also built extensive tunnels and lived in ancient underground quarries.  These tunnels and quarries were dug into chalk and limestone, both of which are soft enough to carve, and some of the soldiers did just that.  There are, of course, the requisite names carved into the walls, but soldiers also left art behind.  There are portraits and symbols, including a praying soldier and a carving of Marianne, the symbol of the French Revolution.

National Geographic September 2014

I know that I should probably be doing October of 2014, since I’m sort of working my way outward from January of 2015.  This issue has an article on Nero in it, though, and I went to Rome in July of 2014, so I’m skipping ahead a bit.  Also, October of 2014 is probably somewhere in my son’s bedroom.  I’ll get to it once I find it. (note: I found it later, in between two Nature Conservancy magazines.)

The Evolution of Diet, by Ann Gibbons, photographs by Matthieu Paley

The Evolution of Diet talks about the “Paleo diet,” which posits that people should be eating a meat-based diet that limits, or eliminates, beans, grains, and dairy products. The theory is that the human genome hasn’t evolved in the last ten thousand or so years.  It starts out speaking kind of positively about the Paleo diet, arguing that the hunter-gatherers’ inclusion of meat in the diet is part of what allowed us to develop advanced brains.  However, as the article progresses, we get farther from this argument.  Gibbons quotes Amanda Henry, who has found evidence that humans have been eating grains and tubers for at least the last hundred thousand years.  Gibbons also quotes Sarah Tishkoff, who makes the point that humans did not stop evolving ten thousand years ago.  We are still evolving and many populations have evolved to digest lactose and starches that others have not.  Oneof the quotes that is highlighted is “The real hallmark of being human isn’t our taste for meat but our ability to adapt to many habitats and to create many healthy diets.” Continue reading “National Geographic September 2014”
