not so ludicrous. Some species are more important than the other. In terms of biomedicine, the lack of a single species having evolved a unique substance could change the human history. Without knowing the list, we can't infer a lot about the impact or lack of impact. Some of those species could be obscure hybrids without real impact, the lack of other could be potentially catastrophic; but the effects would have been forgotten by now and assimilated as "the new normality". This is a glimpse of 1950's.
