Artificial trees to remove CO2 from the air

A new breed of artificial trees able to scrub carbon dioxide from the air could help to reduce greenhouse gas pollution.
The air filtering device will feature strands of a resin-based material that will attract the CO2 and bind to it - capturing the carbon dioxide directly from the air and creating bicarbonate salt.
It could take as many as 10 million 'artificial trees' to lower the atmospheric CO2 concentrations by 0.5ppm per year. While this application may be a bit in the future, the device could have a more near-future use. The CO2 can also be released at will by adding water to the material, which could make it useful as a way to supply CO2 to greenhouse plants in order to help ensure healthy plant growth.
