From some druid site:

Yet die we must. As Sherwin Nuland points out in his book, How We Die, we must die for the sake of our species; if somehow we contrived to live forever, we would quickly overwhelm our environment’s carrying capacity and all perish like lemmings. “Must,” in biological terms, thus carries not only its ordinary meaning of inevitability, but also a sense of appropriateness. Our need for death is personified in Herne the Hunter, sometimes called Cernunnos by the Celts. He is the god of culling, who takes away life for the sake of balance and health in the world.

Note the uncanny resemblance to an Onion article written a year earlier.

Yahzi Coyote has a saying: “All that is necessary to defeat a theologian is to repeat his arguments back to him, changing the word God to any other word.” Likewise, all that is necessary to defeat a bioethicist is to imagine his eyes glowing red and his voice deepening whenever he mentions death, decay, suffering, and necessity.
