How to grow your own fresh air: Kamal Meattle on TED.com

Posted by: Tedstaff

Researcher and activist Kamal Meattle shows how an arrangement of three common houseplants, used in specific spots in a home or office building, can result in measurably cleaner indoor air. (Recorded at TED U 2009, February 2009, in Long Beach, California. Duration: 04:04.)

    This is great for cities and for indoor environments, but what it really speaks to is our need for plants all around us. The world is overpopulated with humans and we are lessening the number of plants, especially large trees, constantly. We need to give plants more value and stop clearing forests and prairie and the like to support our burgeoning population with its excessive consumption and wasteful habits.

      In other words, what we really need is birth control. I agree this is great for the living hell that huge concrete jungles are with their lack of nature, but the real issue is not putting a bandaid on the effect, but changing the cause. We need to return to a more natural way of living with natural homes, gardens and greenspaces for everyone, and a respect for the laws of Nature and not the relatively insignificant laws of Economics.

    Adam, I don’t believe that the presenter is claiming that six plants are sufficient to replace the entire oxygen requirement of a person. I understood him as saying that according to his studies, six plants were needed per person to improve the indoor air quality to a healthy level.

    Has anyone had a chance to check those oxygen production figures?

    If you consider Biosphere 2 they had “a 900 square meter rainforest, an 850 square meter ocean with a coral reef, a 450 square meter mangrove wetlands, a 1300 square meter savannah grassland, a 1400 square meter fog desert, a 2500 square meter agricultural system” for eight people and they still needed to pump oxygen in (they had their maths about right on the plant to person ratio, but curing concrete absorbed oxygen).

    That six slow growing understory plants (the amount of oxygen produced is proportional to sunlight and growth rates) could provide enough oxygen for a person sounds incorrect to me.

    This is cool! I’m not surprised by the discovery just amazed at why the government thinks they have all the smart people in Washington. They need to come see you.
