By the year 2050, the global population will likely be around 9 billion people. The current way we produce food is unsustainable due to its overuse of water, overproduction of land, and heavy use of insecticides, pesticides, and herbicides.
There is a need for sustainable agricultural systems. Two of these systems are hydroponics and aquaponics, which are soilless systems. They are similar, but the main difference between the two is that hydroponics uses added fertilizer while aquaponics uses waste from fish. Basically, they are aquariums that produce food!
Georgia Southern University has conducted research using both hydroponic and aquaponic setups, using crayfish in their aquaponic systems. This video explains their research and gives a demonstration on how you can set up your own aquaponics system.
