Both climate change and extinction are results of our tyranny over the nonhuman world and our domination of, and exploitation of, whole categories of each other - and those, in turn, are clearly linked to agriculture, the cattle-industrial complex, capitalism.

In the 1970s, Safari Club International asked the federal government to approve its import of 1,125 not-yet-killed trophies of 40 endangered species, including gorillas, orangutans and tigers, according to the Humane Society of the United States.

For almost two centuries, American gray wolves, vilified in fact as well as fiction, were the victims of vicious government extermination programs. By the time the Endangered Species Act was passed in 1973, only a few hundred of these once-great predators were left in the lower 48 states.

We read our children stories starring elephants and monkeys and bears to teach them about nobility, curiosity and courage, to warn them against selfishness and stubbornness.

I advise, if you're stymied by a passage or paragraph or plot point - whether it's for an assignment from the outside world or one that comes only from within - get up from wherever you're sitting, walk outdoors, and do nothing but look at the sky for five minutes. Just stare at that thing. Then execute a small bow and go back in.

I don't like names that are clever or made-up sounding.

Without elephants, Africa's landscape would be unrecognizable, yet these animals have fallen by the hundreds of thousands as a result of two enormous waves of poaching in this century - one in the 1970s and 1980s, the other, beginning around 2009, now underway.

The grizzly bears that live in and around Yellowstone make up almost half the population in the lower 48 states, and now those bears are at risk.

Trophy hunters are not Everyman. These world-traveling endangered-species shooters are a far cry from the hunters who spend weekends in the American outback near their suburban or rural homes.

Economic and health statistics, as well as police-violence statistics, shed light on the pressures on American Indian communities and individuals: Indian youths have the highest suicide rate of any United States ethnic group.

Snark describes a cynical position, and I'm not interested in that.

People who are obsessed amuse me.

African elephants have long been thought of as a single species, but a critical mass of genetic studies now proves there are two.

You need not fear my extinction. Fear my proliferation! I've already reproduced!

After numerous generations of people dedicated to killing wolves on the North American continent, one generation devoted itself to letting wolves live.

When 'Watchmen' was published in 1986, the vast majority of comics readers deemed it a watershed in comics history. The 12-part serial comic book was widely acclaimed as a genius subversion of the superhero genre, and it did much to popularize comics to adults.

The question of one versus two species of African elephants isn't about settling an arcane DNA argument; it's about life or death for these majestic, extraordinary creatures.

I worry about the very pernicious way we elevate and separate ourselves from other beasts, the way we rationalize our comfort and ease, our worship of the self, as healthy. It's enticing, but with a terrible taint of evil.

I've seen a few wild grizzly bears, mostly in Alaska and British Columbia, and always from a distance. But each grizzly I've caught sight of was as fearsome and sublime as the last. You never get used to their raw power and massive bodies, or the mysterious intelligence in their dark, close-set eyes.

Most climate debates have focused on cutting the use of fossil fuels. But besides a few high-profile scuffles over fuel extraction in vulnerable wild places like the offshore Arctic, political leaders have ignored fossil fuel production as a necessary piece of climate strategy.

Everyone desires to laugh sometimes, and I want to make that available.

Fiction should be an ethically safe space, free of fancy ideas. It should be dedicated modestly to relationships or escapism or the needs of luscious voyeurs.

I've always been interested in obsessive, insane people.

If you're doing creative work, that work should never feel trivial - even if what you're doing is for hire or lightly intended. Even the mundane doesn't have to be trivial.

Names and other proper nouns shouldn't distract from the language.

Wyoming, home to Yellowstone National Park and the Grand Tetons, is also the country's largest coal producer and one of its largest gas drillers. Two-thirds of the state's gas-drilling rigs are on public lands in the increasingly industrialized Greater Green River Basin.

I had hoped that going to Hiroshima would reveal something small, gritty, and precise to countervail the epic quality of historical accounts.

It seems to me that the time for subtlety in our American life has passed.

People from the rest of the state tend to hate Phoenix, with that typical resentment of the boroughs and the towns for the big city.

At 16, I was more resilient and easygoing than I am now.

Children depend mightily on animals for comfort, inspiration, imagination, and art. And parents have long recognized this.

When I was 16, I went to Berlin - West Berlin, since at that time a wall still divided the city - to live for three months with a family on an exchange program.

Historically, grizzlies ranged from Alaska to Mexico, with at least 50,000 bears living in the western half of the contiguous United States. With European colonization, the bears were shot, poisoned, and trapped to the brink of extinction.

I wanted to write about this tropical honeymoon in part because I had the most drastically terrible honeymoon.

On climate change, we have only a handful of years to make massive changes, according to the scientists. The politicians have to act, and only the people can make them, because Royal Dutch Shell's not going to do it.

More than two million years ago, mammoths and Asian elephants took different evolutionary paths - and around the same time, according to DNA research, so did their lumbering relatives in Africa.

The Safari Club International has worked the legal system hard to try to keep polar bears - threatened primarily by climate change, but also by hunting - on the list of creatures people can import as trophies after shooting.

I'm not calculating enough in the way I approach writing.

Without even knowing why, we believe that to learn how to be human - which we have many years to do, for human beings have longer childhoods than any other species, a feature that to biologists and philosophers alike is one of our race's distinguishing characteristics - children must be surrounded by animal imagery.

About half of all potential future global warming emissions from United States fossil fuels lie in oil, gas and coal buried beneath our public lands, controlled by the federal government and owned by the American people - and not yet leased to private industry for fuel extraction.

Pugs are creatures of habit.

If Oak Flat were a Christian holy site or, for that matter, Jewish or Muslim, no senator who wished to remain in office would dare to sneak a backdoor deal for its destruction into a spending bill - no matter what mining-company profits or jobs might result. But this is Indian religion.

We were a Seuss family. As a child, I read almost all of his books, but the one I loved best was 'The Lorax.'

Shouldn't the cascades of extinction and rapid planetary warming register in our literature?

What makes 'The Lorax' such a powerful fable is partly its shamelessness. It pulls no punches; it wears its teacher heart on its sleeve.

Work-wise, I try not to repeat myself too often. And I have to love whatever I'm doing.

My motto is, if you love something, don't set it free. No matter how hard it struggles. That would be stupid.

If I can't find a way to love it, I let it go. Kind of the opposite of the popular homily.

'Dept. of Speculation' contains numerous enviable lines.

The comic novels I did when I was in my 20s had a harder edge - less sympathy for people. Or a sympathy that was harder to detect: Characters' foibles and obsessive bents were unrelenting, like caricatures.
