David Roberts quotes:

The United States came within a whisker of invading Utah in 1858 and starting a civil war three years before the Civil War. Because the conflict ended up fizzling out, it's not the most dramatic story about the West.

Nobody realizes that Mormons were the first Americans to settle Las Vegas.

During the Spanish conquest of Mesoamerica in the 16th century, the Catholic Church's Friar Diego de Landa supervised the burning of hundreds of Maya codices - fig-bark books rich in mythological and astronomical information. Only four Maya codices are known to have survived.

I knew that alpaca wool, with its cashmere-soft weave, had been transformed into cuddly knick-knacks ranging from pillows to teddy bears. But through selective breeding over the past 6,000 years, alpacas have so diverged from their llama cousins as to become quite different animals.

It's not at all naturally human to see something like the Grand Canyon as beautiful.

It's about the climate-change "denial industry", ...we should have war crimes trials for these bastards - some sort of climate Nuremberg.

When you sling a saddle atop a llama's back, just after he's rolled in the dirt to scratch the unscratchable tickle of having lugged an ungrateful hiker's 90 pounds of impedimenta another eight miles along the trail, you're struck by how matted, coarse, and snarly the wool seems. But that's why it makes for versatile outdoor wear.

When we've finally gotten serious about global warming, when the impacts are really hitting us and we're in a full worldwide scramble to minimize the damage, we should have war crimes trials for these bastards-some sort of climate Nuremberg.

I went to the Grand Canyon with my family when I was about 8 years old, and I had a very blah experience. I think the scale of it is too huge - you don't appreciate it.

Perhaps the greatest Maya mystery of all is the cause of the civilization's abrupt decline. The last dated stela erected at Tikal was put up in A.D. 869; the last anywhere in the Maya world, in 909.

As scientific research demonstrates, llama wool's very coarseness and its range of fibers from fine to thick mean that it can be woven into clothing that's superior to down, fleece, sheep wool, and alpaca wool in criteria ranging from warmth to water resistance to usable life.

The black line is carbon emissions to date. The red line is the status quo - a projection of where emissions will go if no new substantial policy is passed to restrain greenhouse gas emissions.

People say 'Why do you make pots?' Because I'm compelled to - life isn't right without it.
