Sea Vegetables (Algae as Food for Man)

Abstract

Seaweed as a staple item of diet has been used in Japan and China for a very long time. To a lesser extent various species have been employed in Europe and North America. On the Continent and larger islands where normal agriculture can be supported, there is no great demand for seaweed as food. There are, however, many islands where conventional agriculture cannot meet local demands, and it is here that people have, of necessity, relied on the sea as a major source of food.
