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

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

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

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

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.

Pugs are creatures of habit.

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.

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.

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

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.

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.

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.

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

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.

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.

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

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

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.

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

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

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.

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

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.

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