A resin that pulls carbon dioxide out of the atmosphere may -- in the future -- join in the activity of natural plants in absorbing atmospheric carbon dioxide, writes David Biello. The resin is actually more hungry for CO2 than plants and converts the carbon it consumes into bicarbonate, a kind of salt. It would take many items using the resin to make a significant difference in CO2 levels, but the product is much less expensive than other methods being looked at, Biello adds.
