Supplying the people of the world with sufficient food has been a constant issue ever since the population has begun to increase considerably. Now even movies are placing food shortage at the center of their Sci-Fi genre. Homemade food might be a possible working answer, people all over have resorted to such a solution in the last years. But how to go about more sustainable food systems?
“Aquaponics, is a food production system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria into nitrates and nitrites, which are utilized by the plants as nutrients. The water is then recirculated back to the aquaculture system.”
