EDITOR: I'm hopeful you've received a deluge of outraged mail in response to the Dec. 1 article about the U.S. Fish and Wildlife's plan to poison mice on the Farallones.
Where is the logic in killing one creature to save another? The dangers to ashy storm-petrels seem more the result of man-made threats such as global warming and pollution than natural predation.
How does the loss of 100 birds to owls out of a colony of 10,000 result in population decrease? It's not just whether the problem requires management; it's the obscenity of the scorched-earth method being suggested. This is an incomparably important ecosystem. To resort to aerial poisoning before other options are even attempted is ludicrous.
Also, there seems to be a lot of conjecture in the hoped-for outcome. What if the owls decide the baby petrels will do just fine once the mice are gone?
And why the concern at all from the U.S. Fish and Wildlife Service when it won't grant endangered-species status to the petrel?
Killing is counter to the concept of environmental action. It is our duty to manage in a responsible way, which the current proposal is not.
