American Trees
Where did the old forests go? Sailing masts for the British navy. Staves for wine barrels. They went into railroad cars, “snake fences,” and orange crates; they went up the hugely inefficient chimneys of settlers… From American Canopy, a May 20 column in the Sunday Globe.





Groundwater supplies all over the nation are dropping, even in the relatively wet Southeast. Wetlands have become as rare as sea-run salmon, and Lake Mead, which supplies 90 percent of Las Vegas’s water, could be dry by as soon as 2021. From
There’s certainly a chance we would not have heard of John James Audubon, still probably the world’s most famous ornithologist, if he’d decided not to get on a ship in New Orleans in April of 1826. Or if Lucy Audubon hadn’t supported her husband’s wishes to do so… An outtake from

Oh, you know, the idea that if the cosmos is infinite, it’s large enough to contain infinite versions of everything. Infinite copies of you in infinite universes reading infinite copies of this newspaper. From
The American writer Eleanor Clark, upon moving to Rome in the late 1940s, found herself swamped by the city’s “mess and the blazing sun, the incongruities, the too-muchness of everything.” That’s a pretty fair analogy for how one feels reading Chasing the Sun: it’s fascinating, but the “too-muchness” of the experience gradually overwhelms.

Once we improve sequencing and cell-transformation technologies, a well-to-do couple hoping to have a child could potentially create tens of thousands of embryos. Screen them all, select the strongest, smartest, prettiest, and — bingo — designer children. From
Without insects we’d have no vegetables, no birds, no flowers, no hamburgers, no cotton, no trout. No ice cream! No rose bushes! Terrestrial ecosystems would collapse. Dead bodies would rot in the streets. From
For years researchers have produced riveting evidence that genes and environment interface dynamically. Yellow grasshoppers can turn black if exposed to charred environments. Fertilized crocodile eggs can become male or female depending on temperature. Put the offspring of rats who test well solving mazes in boring, unstimulating cages and the pups will grow up to be terrible at mazes.. From
Labs around the country are finding that glial cells are involved in epilepsy, fetal brain development, mental illness, and the even generation of new neurons in adults. Some glia form a kind of super-aggressive Secret Service that can tunnel through the snarls of dendrites and attack intruding organisms. Still others serve more like maniacal sidewalk sweepers, collecting and absorbing discarded potassium ions that are released by neurons when they fire. From
Now we Americans rely on honeybees to pollinate our apples, almonds, blueberries, melons, onions, turnips, celery, squash, among dozens of other fruits, nuts, and seeds—a third of every forkful you put in your mouth. They also pollinate the alfalfa that feeds our beef and the cotton that’s spun into our T-shirts. All told, a Cornell University study values the contributions of bees to the U.S. economy at somewhere around $15 billion. From 
Can we transform media, divorce money from politics, build a carbon-neutral society, protect much larger sections of our oceans, and find leaders that can put sustainability into a moral context, as Lincoln was able to do with slavery? If we fail, the lives we’ll ruin are not only those of tree frogs or spotted owls or people who live in low-lying coastal cities. The lives we’ll ruin are the lives of our children. From
One way to look at the history of modern science is to say that it represents a century-by-century reordering of common sense. Copernicus showed us we weren’t standing still at the center of the universe. Galileo showed us that all motion is relative depending on who observes it. Darwin showed us that our bodies and minds are the result of eons of natural selection. None of these things seemed true at first glance. An outtake from
When British soldiers arrived in Jamestown in 1676 to quell a Colonial rebellion, a few daring farmers slipped some jimson weed into the British chow. The soldiers hallucinated for 11 days. “One would blow up a feather in the air,” writes a historian, “another would dart straws at it with much fury; and another, stark naked, was sitting up in a corner like a monkey.” From
The Milky Way belongs to a cluster of galaxies (we call it the Local Group), which in turn belongs to a vast conglomerate of tens of thousands of galaxies (the Virgo supercluster). Spiral-shaped, ellipse-shaped, sombrero-shaped – in the visible universe, at any given moment, there are hundreds of thousands of millions of galaxies. Maybe as many as 140 billion. All those galaxies, stuffed with all those stars, stuffed with how many worlds? If our sun is one in 10 sextillion, could our Earth be one in 10 sextillion as well? Or the Earth might be one – the only one, the one An outtake from
One can only hope, however naively, that in another 200 years, Darwin’s theory of natural selection will have ceased to be so controversial. Two centuries from now we may understand exactly how life originated on Earth. We may be synthesizing new kinds of life in laboratories. We may have even detected it on a distant planet. From
Morton points out that phrases like ‘climate change’ or ‘global warming’ brutally simplify what human inputs have done to the global atmosphere over the past two centuries. As utilitarian as phrases like these seem, to call what’s going on in Earth’s atmosphere ‘climate change’ is akin to calling what’s going on in global markets, ‘financial change.’ An outtake from
The most prominent and mystifying of Brooks’s 13 anomalies are the twin riddles of dark energy and dark matter. These enigmas account for 96 percent of the mass in the observable universe, yet their existence remains inferred and hypothetical. Some of our smartest cosmologists have invested two decades in figuring out dark matter, but we still don’t know what it is. From 

The implication was that big-brained Homo sapiens, perched at the top of the topmost twig, formed the pinnacle of evolution. This is a fallacy. Evolution proceeds by blind chance, not by design. We are adapted creatures, but we are not optimized creatures. As counterintuitive as it might seem, it’s inaccurate to suggest that humans are more evolved than, say, horseshoe crabs, which have been living and dying for 400 million years
