Synthetic Food

The use of synthetic food for people, animals, and fish is becoming common. This food is usually less expensive to manufacture than natural food grown or raised from organic sources. Manufactures can put hormones and nutrients into the food to increase the growth and supposedly the health of those eating the food. In some cases, body parts of butchered animals that can't be used for anything else are placed in the food to provide inexpensive "filler" to increase the substance and weight of the food.

Some scientists are concerned about the manufacturing of synthetic food, and they are researching the processes used to make the food. Here are links to some of their research.
People are eating more and more fish. To meet rising demand, fish are increasingly being cultivated in fish farms. Aquaculture is the fastest-developing branch of the global food industry, with annual growth of nine per cent. This rapid rise is also pushing up demand for fish feed, producers of which are facing a formidable challenge, because the supply of fishmeal and fish oil -- important ingredients in feed -- is dwindling. They are set to be replaced by crops such as soya, maize and rape, but the trouble with these is that feed pellets made from them might contain pesticides.
