Plants are the lungs of the earth: they produce the oxygen that makes life possible, add precious moisture and filter toxins. Houseplants can perform these essential functions in your home or office with the same efficiency as a rainforest in our biosphere. In research designed to create a breathable environment for a NASA lunar habitat, noted scientist Bill Wolverton discovered that houseplants are the best filters of common pollutants, such as ammonia, formaldehyde and benzene - chemicals released by furniture, carpets, building materials and photocopiers and then trapped by closed ventilation, leading to a host of respiratory and allergic problems now called Sick Building Syndrome. Here Dr Wolverton shows you how to grow 50 plants as accessible and trouble-free as the tulip. He rates each plant for its effectiveness in removing various pollutants.
