One solution to the nations termite problem could be growing in the fields of Africa. Seaphire International of Phoenix is developing termite-proof particleboard made from sea asparagus, a crop harvested annually in Africa and Mexico for its oil and asparagus tips. Because the plant is irrigated with seawater, the board has a salt content of 450 milligrams per ounce-salty enough to ruin the appetite of hungry termites. Particleboard is used for cabinetry, flooring, and other nonstructural elements of a house. The new board is as strong as other medium-density agro-based particleboards, such as those made from rice, straw, and soy. In addition, says Seaphires Roy Hodges, the boards high salt content retards fires (its retardancy is comparable with that of particleboard specially treated to resists fire). The new board should appear commercially in about a year, first in deforested Eritrea-a small African country on the Red Sea with the worlds largest sea asparagus farms-then in the United States around 2004. Seaphire plans to expand its farms in Mexico to manufacture boards for the United States. That may help alleviate the termite problem that plagues Southern California and other warm regions.The new particleboard will first be produced in Africa because

Some people do experience mild side effects like upset stomach, headaches, difficulty sleeping, drowsiness, anxiety and nervousness. These tend to g away within a few weeks of starting treatment and usually arent serious enough to make most people stop taking them.This article would probably make depressed people feel more
