Well, think of it this way Syphon. If we produce exactly what we need and nothing more (assuming that algae reproduces at an exact rate, it should be relatively effortless, given how anal most scientists are, to track and calculate), and keep a quantity in reserve, than it shouldn't harm any natural ecosystem, as what is creating and feeding it would be humans, and we'd control all exterior variables.
That's exactly what I meant.
Tending algae is serious business.
None.
