Dave Becomes Even More Insufferable (Thanks Charles C. Mann!)

I just finished the new Charles C. Mann book The Wizard and the Prophet (including both appendices) and now I'm chock full of facts and leaking whole lot of half-assed opinions; the Wizard is represented by the so-called father of the Green Revolution, Norman Borlaug, and the Prophet is symbolized by conservationist and ecologist William Vogt . . . Prophets prophesy doom unless we "cut back! cut back!" and Prophets preach conserving wetlands and open spaces, reducing consumption, utilizing bottom up energy solutions, and basically halting constant economic growth and development, which comes at the cost of the earth's resources; Wizards are the "techno-optimists" and they are sure that we will think our way through all these problems, often with large scale projects-- whether they be to harness wind, sun, and tide, desalinate the oceans, or curb global warming by putting sulfur-dioxide in the air; there's also a lot about wheat in the book, Norman Borlaug painstakingly bred super-wheat in order to feed the starving masses (a fun fact, wheat is incredibly diverse genetically and thus there are infinite variations to breed, while humans are incredibly similar genetically-- chew on that, racists!-- and two humans who look nothing alike are more similar genetically than two chimpanzees from the same troop) and Mann describes this wheat breeding in great detail . . . I definitely skimmed this portion of the book-- it's more intense than the corn section of The Omnivore's Dilemma-- but I'm certain that if you select for extra rubisco, throw in a little Haber-Bosch, then you're feeding the billions . . . but a planet with ten billion humans will not resemble our current conception of earth (although we are rapidly approaching this future as far as biodiversity is concerned, see various posts on The Sixth Extinction) and the Prophets worry that super-wheat will simply exacerbate the population bomb . . . and there's a chance that both the Wizards and the Prophets are wrong and Lynn Margulis is right; Margulis, one of the most prominent researchers in the field of microorganisms, believes our planet is a Petri dish, and like most other species, we will breed and exceed-- we will use up all our resources until calamity strikes . . . there are a few indications that she could be wrong-- but nothing to write home about-- violence is at an all time low, in an exponential sense, and there have been some bottom-up successes in Burkina Faso that indicate that we could reforest the desert, creating a giant carbon sink, reinvigorated soil, and a more humid landscape . . . anyway, the conflict in the book, between the Wizard's desire to create technology "to soar beyond natural constraints" and the Prophets hope that we can learn to live in a "steady state" negotiation with our planet, is going to come to a head in our lifetime and Charles C. Mann does a fantastic job with an even-handed look on how things might change (I also highly recommend his two other noted books, 1491 and 1493, which describe the Americas before and after the Columbian exchange).

Dave Should Be a Future Leader (According to Obama)

I was pleased to learn that Hillary Clinton agreed with me on the importance of Robert D. Putnam's new book Our Kids: The American Dream in Crisis, but President Obama trumps her with his reading list for future leaders . . . I've read four of the ten:

The Sixth Extinction by Elizabeth Kolbert;

Thinking Fast and Slow by Daniel Kahneman;

Behind the Beautiful Forevers by Katherine Boo;

Sapiens: A Brief History of Humankind by Yuval Noah Harari;

and these were definitely some of the best books of the past decade (read my reviews if you're in need of some hyperbole) and so Obama either really loves to read, or he reads my blog and respects my reviews, or perhaps he's got really good reading advisers-- it's probably a combination of the three-- and I realize that this is a political "signal" to release this list, as it indicates that the President values high quality non-fiction, just as Donald Trump could never admit that reading books is necessary, as it would alienate his constituency and mark him as an elitist intellectual communist, which is why he gets his information from "the shows."

Words for Beyond Words

I finally finished Carl Safina's book Beyond Words: What Animals Think and Feel and it's one of the most powerful and moving things I've read in a long time-- I actually had ambitious plans to summarize numerous portions, but the book is over four hundred pages and dense with details, so you're going to have to trust me, this is a really good one; here are a few things to whet your appetite:

1) Lyell Watson's description of an old lonely matriarch elephant standing beside the ocean enjoying the ultrasound rumble of a blue whale and possibly communicating back with her own deep voice: "the blue whale was on the surface again, pointed inshore, resting, her blowhole clearly visible . . . the largest animal in the ocean and the largest living land animal were no more than a hundred yards apart, . . . commiserating over the back fence of this rocky Cape shore";

2) the cruelty of the ivory trade, both to human-slaves and to elephants . . . as late as 1882, slavers chained humans together and had them carry the heavy tusks from the Upper Congo to port-- a 1000 mile slog-- and, as protocol had it, if you got sick, you were killed (to prevent malingering) and if you grew to weak to carry your tusk and your child, then your child was killed, because, as the headman logically explained: "We cannot leave valuable ivory on the road . . . we spear the child and make her burden lighter . . . ivory first";

3) the descriptions of wolves in Yellowstone, their infinitely complex personalities and hierarchies and forays and betrayals . . . the touching moment when Wolf Twenty-one, at the tail end of his years, watched his pack hunt an elk and then headed in the opposite direction, to the top of Druid Peak-- his favorite family rendezvous point-- where he lay down in the shade of a big tree and died . . . on his own terms;

4) the tool use of various animals, including apes, chimps, elephants, insects, dolphins;

5) the self-awareness and theory of other minds that dogs, dolphins, killer whales and primates possess;

6) the variety of killer whale types-- fish eaters, whale eaters, dolphin eaters, seal eaters-- and the various strategies that different tribes of whales use to hunt;

7) the intelligence and creativity of dolphins . . . you can train dolphins to "do something new" for a treat . . . and they will synchronize this creativity with another dolphin . . . my students have trouble with that task;

8) the vast intelligence, empathy, and abstract thinking ability of killer whales . . . and the many injustices done to them in the wild and in marine parks;

9) a lot of other stuff . . . this book is groundbreaking and belongs on the same shelf with two other recent great books about nature: The Sixth Extinction and Wild Ones . . . read all three before you die!

Are You Reading It Yet?

I'm sure, due to all my hyperbole and ultimatums,  you are well into Elizabeth Kolbert's The Sixth Extinction, but if you haven't finished, don't get discouraged, as the book has a slightly upbeat ending-- though the evidence is nearly incontrovertible that not only are we inadvertently killing off species at a unprecedentedly rapid rate -- with climate change, ocean acidification, and a reshuffling of native and invasive species -- but there was probably no time in the Anthropocene when humanity was "one with nature,"as the "pulse" of colonization of primitive people's across the globe went hand in hand with a devastating loss of super-awesome mega-fauna -- nothing makes more more melancholy than the list of animals early North American natives hunted to to extinction (glyptodonts, cave bears, dire wolves, wooly mammoths and rhinoceros, giants beavers, giant sloths, giant camels and llamas, American lions, American cheetahs, etc. etc.) . . . and not only that but we also wiped out our main humanoid competition, the neanderthals, but due to the "leaky-replacement hypothesis" and some very adventurous swinging souls, the good news is that present day homo sapiens posses 1-4 % neanderthal genes -- so the neanderthals aren't totally extinct, they survive inside of us . . . and while there may be no way to stop this sixth extinction, Kolbert admires the folks that are trying, as these are the kind of people who will "give a Hawaiian crow a hand-job," stick their arm up a Sumatran rhinos anus, and cryogenically freeze and preserve the genes of many species just in case we can resurrect them in the future . . . but it all may be too little, too late, but perhaps next time around, in a few million years when creatures have had a chance to evolve diversely once again -- if we are still in the picture-- we will do a better job of it.



Due to Extinction, There Will Be No April Fool's Post This Year


I haven't gotten much response indicating that all the people out there in the human race are obeying my command to read Elizabeth Kolbert's book The Sixth Extinction: An Unnatural History, and so I am canceling today's April Fool's sentence due to mass extinction (caused by humanity) and there will be no more April Fooling on this blog until the Anthropocene ends, the human race fades away, and the rats and cockroaches explode into all the available evolutionary niches, ushering in a new age of very gross bio-diversity that we will not be around to name (but you can enjoy previous April Fool's posts, as I'm not so hardhearted as to remove those . . . it's not like we wanted to kill all these creatures, right?)

Book Review with a Side of Hyperbole, Please . . .


If you're only going to read one book this year, it should be War and Peace, but if you're going to read two books this year, then the other one should be Elizabeth Kolbert's The Sixth Extinction: An Unnatural History; while the message is grim, the writing is clear and engaging, and Kolbert narrates her own adventures in places as far-flung and varied as the Amazon, the Andes, the Great Barrier Reef, Italy, Vermont, and a littered fossil-filled stream in an undisclosed location near a ball field in the vicinity of Princeton, New Jersey to provide a counterpoint to some shockingly depressing lessons and predictions, and while I shouldn't be doing this, because you must read this book, I will provide a thumb-nail sketch of the content . . . before humans, there were five major extinctions, and "as in Tolstoy, every extinction event appears to be unhappy-- and fatally so-- in its own way"; there was the well-documented K-Pg extinction event (formerly known as the K-T extinction event) which wiped out the dinosaurs sixty-six million years ago, when a huge asteroid hit the earth near the Yucatan Peninsula, but the four other extinction events are more mysterious . . . they may have been because of climate change, shifting continents, habitat loss, and/or ocean acidification (global warming's "equally evil twin") and Kolbert wants to welcome us to the sixth extinction event, the Anthropocene, where all of these forces -- cranked up to a much faster velocity-- are wiping out species faster than we can count them, and there is an apt comparison deep in the book, after Kolbert recounts the story of the brown tree snake, an invasive species that has voraciously eaten every indigenous bird, mammal, and reptile on the island of Guam, and she cites the great nature writer David Quammen for this analogy: "while it is easy to demonize the brown tree snake, the animal is not evil; it's just amoral and in the wrong place . . . what Boiga irregularis has done in Guam is precisely what Homo sapiens has done all over the planet: succeed extravagantly at the expense of other species."

People Ruin Everything


More from The Best American Science Writing of 2010: Elizabeth Kolbert, in her essay "The Sixth Extinction?" points out that whenever people come to town, all the cool creatures are wiped out; the mastodons, mammoths, giant beavers, dire wolves, short-faced bears, giant ground sloths, toxodons, and saber tooth tigers died out just after we came to the Americas . . . the giant wombats, giant tortoises (as big as a VW Beetle!) and giant ten foot tall kangaroos died out soon after we colonized to Australia; this pattern holds true for New Zealand, Hawaii, and pretty much everywhere else-- the big and cool looking stuff can't survive in the places we colonize, but this is happening with smaller creatures as well-- there is a great die off of amphibians happening right now, notably the Colombian golden frog (which is technically a toad) and bat populations are also rapidly declining-- and Kolbert explains (and demonstrates) that this is probably caused by a chytrid fungus spread by humanity called Bd (actually it's called Batrachochytrium dendrobatidis, but by the time you finish saying that, another species has gone extinct) but, luckily, some species are not affected, including the hardy salamanders that we discovered in the woods near the litter strewn banks of the polluted Raritan River, but it does make me worry that we might have to stop visiting our "Jersey tough" amphibians.
