What do?
They're both equally exciting, they might not even accept me for the volunteering project considering I have 0 experience in the field.
But then again they don't seem to be looking for specialized people.

And even if the allowed me to take a couple of weeks off I wouldn't be able to join the trip because it's thousand of km from civilization.
