Ran across these numbers in a microbiology textbook I'm considering adopting for my class. While not directly marine related, it bears on the subject of conservation. These numbers are to produce one kilogram of edible protein

Spirulina algae requires 0.6 square meters of land, 2100 liters of water and a total energy input of 35,000,000 kJ

Corn requires 22 square meters of land, 12,500 liters of water and a total energy input of 117,000,000 kJ

Grain Fed Beef 190 square meters of land, 105,000 liters of water and a total energy input of 4,560,000,000 kJ

will did more research into these numbers, but definitely

Food for thought.
