Gustation and ecology

Due to its high natural deliciousness the pancake, alas, is very nearly extinct. The decline in numbers was swift, perhaps inevitable. Unfortunately for many organisms, their deliciousness - or lack thereof - is largely not under their control, but rather the domain of the organism performing the tasting.

What lesson can be drawn from this? One which immediately comes to mind is of utility. If the quality of deliciousness can result so swiftly in the near-extinction of the pancake, and if it is property existing only in the context of an observer - a taster - then a solution to certain pest problems readily suggests itself.

If humans were modified to find cockroaches supremely delicious, for example, then they would soon cease to suffer from cockroach infestations. Except, perhaps, from the lack thereof.

Watching The Lion, the Witch and the Wardrobe and the Professor, when talking with the children on the possible truthfulness of Lucy's tale of Narnia, used the same 'Lunatic, liar or Lord' argument I am told C. S. Lewis used as an argument for Jesus as Christ.

Now I am wondering if this is from the novel or if it were added in to the film. It never seemed a convincing argument, since there seemed far too much unexamined space in the first two parts of the trilemma. I have not yet seen Lewis' own formulation, though (beyond this).
