Conventional Agriculture vs. Aquaponics for Sustainable Food Systems

I'm sharing a couple of diagrams I'm working on for a paper I'm working on. In the paper I'm advocating for increased research into aquaponics as a possible significant contributor to future sustainable food systems. I'd greatly appreciate any thoughts on the idea in general, and more specifically, on the drawings below.

What do you think? Are they a fair conceptual representation? Am I leaving anything out? Don't hesitate to jump in with your thoughts.

Thank you,

Chris
