"Ethics" article poses interesting questions. The pre-sapient scenario reminds me of a story in Stephen Baxter's Vacuum Diagrams in which the main characters explore an object in the Oort cloud and their body heat nearly destroys a civilization then didn’t know was there.

I finally got around to reading the story you recommended, Tony - my "to read" list is very long. The story is an apt metaphor for so much of what humans do, from pumping greenhouse gases into the air to personal relationships: We enver really examine, or maybe even can know, the full consequences of our actions. Thanks for the suggestion!
