One solution to the nation’s 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.
