Can anyone identify when onscreen (season and episode, or movie) Spock (or someone else) said this (or something very near to it)?
"To destroy your home planet's ecosystem for imaginary wealth is highly illogical."
Or did he (or anyone on Star Trek) not say it?
See this quotation attributed to Spock, for example, in this product on Ebay, as well as on various meme-blogs:
The quotation sounds familiar (particularly the "imaginary wealth" bit), it sounds like Star Trek ethos, and it sounds like a comment Spock would make (even without the word "illogical"). But I can't find a source for it (I tried searching various sources on the web, including http://www.chakoteya.net/). Thanks!
By the way, I'm familiar with the similar Quark quotation: "They irradiated their own planet?!" (Deep Space Nine, season 4, episode 8, "Little Green Men")…as well as the similar Spock quote: "Judging by the pollution content of the atmosphere, I believe we have arrived at the latter half of the twentieth century" (Star Trek IV: The Voyage Home).
