Whether snipping little bits of plants to make more, sowing seeds or simply piling up dead leaves for compost, your efforts are assisting the oxygen factory. Recently on the oxytherapy mailing list, the topic was raised of those house plants that help to remove toxic gases from the air. Someone wanted to know what plants were on the list and how many one should have in the home. The NASA list has been published ad nauseam in many magazines, newspapers and in radio and television. To my way of thinking, the robotic reaction of buying one of each of the plants on the list does offer a solution.
All plants transform air into a more oxygen-rich variety.

For the most part, they find that my advice is detrimental to the sale of the products their advertisers offer.
