What’s the answer? Aquaculture.
At least it’s one of the answers. Aquaculture, also known as fish farming or aquafarming, is the practice of farming aquatic organisms such as fish, shellfish, and aquatic plants. This practice is not a new idea and, in fact, has been around for thousands of years, with the first historical accounts of aquaculture dating back to 2500 BC.

Aquaculture is a very viable method of food (protein) production, about seven times more efficient than cattle production.
We raise animals for human consumption but what we often don’t think about is the food that these animals must eat and, subsequently, the resulting demands on natural resources. Farmers measure these demands by using a food conversion ratio (FCR), which is the estimated amount of feed required to gain one pound of body mass in the animal being raised. You might be surprised to learn that it takes around 6.8 pounds of feed to produce 1 pound of cattle body mass. Fish, on the other hand, only need 1.1 pounds of feed to produce 1 pound of body mass. To meet rising demand for food with limited land (and water), we are going to have to produce more efficiently. Raising fish is about seven times more efficient than raising cattle, about three times more efficient than raising pigs, and about one and a half times more efficient than raising chickens.
