"Unfortunately, yes. Some amount of unusual flora and fauna is almost to be expected given this clearly isn't any world that we're familiar with? But even so, there seems to be a rather excessive amount of things that can detrimentally effect someone."

It's perhaps not quite as harmful as it could be, perhaps. But only in the fact that no one has so far died, or been transformed into something else, and given the wide variety of other way there are for people to become ill or injured even on a world that doesn't boast the species this one does, that's not saying a whole lot. Especially when they're having to find out what everything does pretty much by trial and error.

"If we can find one that looks like it would be relatively easy to climb, that wouldn't be a bad idea, actually."
