Animals with traits that are beneficial to the environment can live longer and potentially contribute more to the gene pool.
The latter is all that matters (biological fitness, or how many viable offspring are produced) in natural selection. Lifespan and any greater purpose (benefit to the environment) are not applicable.
As I see your revision it seems you are more careful in describing NS, but does your view on NS escape being a tautology?
Since contributing to the gene pool is the only definition you give, it either has no result (the author calls that a 'lame' definition, since it isolates the proces of NS so that it no longer tries to explain evolution), or the result is a difference in the gene pool (that is: a difference in the frequencies of genes) after one or several generations, and then we have a tautology again.

All tautologies are truisms, but not all truisms are tautologies.

Then it is still a tautology

You can know it's beneifical to a particular individual, but it's harder to say for populations.

I'm more inclined toward his logic, but possibly toward your conclusions.

we can't really know ahead of time what makes a specific trait benefical in that environment

Did you perhaps mean "beneficial in the environment" rather than "beneficial to the environment"?

yes. I did not really phrase that very clearly. *NM*

100% I think Moriaine is a very beneficial trait that contributes a lot to the RAFO pool *NM*
