One proposal for resuscitating Japan's moribund coastal fishery is to propagate artificial underwater forests, in a plan to double the marine resources available. Created on a nationwide scale, artificial underwater forests of kelp (konbu) could be grown as food, animal feed, medical ingredients, fertilizer and industrial feedstocks. These underwater forests are also expected to have an environmental cleansing function. One proposal for resuscitating Japan's moribund coastal fishery is to use existing seaweeds culture techniques to create temporary marine forests with good care by coastal fishermen every year. Combining small, medium, and large scale kelp and other seaweeds culture along Japan's coasts makes artificial marine forests to prevent eutrophication at coastal waters, double fisheries production, and add economic values to the people through utilization for foods, feeds, medicine, fertilizer, and other industrial resource materials.

The planting efforts began in 1988 as a task of the Hokkaido Fishing Co-op Ladies Auxiliary. Soon everyone in the fishing co-op was involved in "planting forests for fish," and today it is one of the region's most prominent activities. In the 16 years to the present, some 600,000 plants were planted. Inspired by the slogans "plant trees to spawn more fish" and "preserving the natural environment of 100 years ago, 100 years from now," the effort continues today.

The rapid growth in the world's population is destroying the food-chain pyramid, threatening an arrival of a century of hunger. The solution is to reduce the global population, but that will take three generations-an entire century. To survive this long transitional period, we advocate the use of drifting Megafloats on which two or three crops a year can be planted.
