More scientists agree that every modern house has some kinds of indoor pollution．People began to notice the problem in the early 1 9 70s. Builders made buildings in which the flow of air between inside and outside was limited．They also used manmade building materials which are known to let out harmful gases．As the problem became more serious，scientists began searching for a way to deal with it．They discovered a natural pollution control system for buildinggreen plants.
