Algae — resource or scourge

In the quest for new sources of energy, renewed interest and consideration has been given to seaweed. Their biomass is large, and development of marine farms could conceivably be economically advantageous and environmentally tolerable. Large seaweeds are dominant in most shallow coastal waters; various species have been gathered and/or cultivated. Emphasis in Part I is placed on kelp. Marine farms could be more productive than natural ecosystems. Artificial upwellings can enhance productivity. Methane and other gases, electrical power, but also food, feed, and fertilizer can be produced from seaweed through physico‐chemical processes, or by direct use. Large ocean farms, however, pose environmental problems ranging from pollution to cluttering. Part 2 (Economies and Environment) will appear in the next issue of this journal
