artificial trees

Heard this thing about artifical trees being used to capture CO2 emissions. Personally, i'm not convinced. It's like Carbon Capture and Storage, and reflects how little has been learnt from the current economic downturn/crisis/recession etc.
Just sticking it all underground does not solve the fundamental issue of producing too much crap and killing the planet.
I'd much prefer some systematic and sustainable solutions that actually address the problem at hand, not a sticking plaster, though i accept they would have a role to play.
To me, massive green taxes with tax breaks and incentives to better alternatives
