Why can't we physically reduce CO2 in the atmosphere?
Advertisements [?]
When I was in high school chemistry class, we learned a procedure in lab to convert carbon dioxide into oxygen and solid carbon.

Why can't this procedure be done on a grand scale? If we can reduce the carbon dioxide levels in the atmosphere, it will ease global warming.
