Haidee's
voice booms out, and you both jump. You listen in as the bionauts talk,
half to you, half among themselves.
Theories.
You want a theory? Okay, here's mine. Foster's plants are not producing
enough O2. Plants produce O2 as a result of photosynthesis. Not enough
photosynthesis - not enough oxygen. Plants depend on light for photosynthesis.
If Foster hasn't been giving his plants enough light, that would explain
why he's running out of oxygen.
Now
Jerrold speaks up:
I believe other creatures are using up his O2. Each pod has crawdads, shrimp and creatures in it - they're necessary to keep the plants healthy and the ecosystem in balance. But if their numbers get out of control - they start to use up more oxygen than they should.
But now a new voice breaks in:
You're crazy, both of you.
The new voice is Foster's.
