You dig it. You bastard, I hope you acknowledge the pun :D

I mean, a botanist I guess would be responsible for charting all the weird and wonderful plants of a new world. So who knows what could be growing- trees that glow in the dark due to a luminecent compound, or crazy shit like that. Also, they'd be responsible for food in time- I mean, even if the exos can keep going, there's only so long our people inside will, so the local food sources will eventually come down to that.
