NASA Research Focuses on Living Plants
We all may be breathing a lot easier thanks to promising NASA research on a most sophisticated pollution-absorbing device: the common office and house plant. The Interior Plantscape Division of the Associated Landscape Contractors of America has joined with NASA in a two-year program to study the effectiveness of popular office plants in cleaning indoor air. NASA research on indoor plants has found that living plants are so efficient at absorbing contaminants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations. Dr. Bill Wolverton, a NASA research scientist, believes that NASA's findings about indoor plants have some down-to-earth applications for cleaning dirty indoor air. He estimates that 5 to 20 Golden Pothos and Spider Plantscan clean and refresh the air in the average 1,800 square-foot home.
