Just banning "Trees" would save a million trees

Kay Ryan was named poet laureate of the United States. "I might take it upon myself," she said, "to prevent all bad poetry from being published."

She's a poet,
And boy, does she know it.
Just because she's the Laureate,
She feels entitled to excoriate
The poetasters among us?
As if we were fungus,
To be scraped away.
But how can say
What is superior in verse
Without preserving what's worse?
