')Only if you really believe humans are dependant on anything besides their crops. And really, I doubt civilization will even be based on biological humans in several hundred years.
oh christ, another star trekker.
Lets start simple.
Have you, Dezakin, ever heard of something called pollination? Its a process, a function carried out by an organism, often a bug but can be a bird, animal, or the wind (depending on crop). Without a pollinator, most of your crops are just weeds. Just crops?
You might retort that farmers can ship in pollinating bees in hives, which indeed they do. Thats fine for bee pollinated crops (you eat much canola?), but... unfortnately US bees are suffering their own dieoff due to the veroa destructor (sp?) mite. Just crops?
Your crops also reqs good soil ecology, what it is that makes nutrients available to crop roots and without which they don't grow: bacteria, fungi, microfauna, and more. (fertilisers replace some/most NPK demand, but thats far from all plants require of soils). Just crops?
I could go on, but it'd take many years and we don't actually know the half of it. My point is, even if humans only needed crops (laughable idea), they in turn require at least hundreds of other species.
If its all so easy, if endless nuke energy is there waiting for us, you go find us:
a) a working breeder reactor
b) a human living on crops alone, using no other biological products (making own oxygen, fresh water, ...)
oh, and computer science? Electronics with a big head. Computer science as a good intro to planet systems science?
