No chemical compound in the atmosphere has a worse reputation than CO2, thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control and energy production.

I've always liked making things that don't deny the medium that they're made in. If it's collage, I'm happy for it to look like that. If it's a film made with computers, I don't mind that it looks like a film made with computers as long as it still has a feeling or a mood or an atmosphere that is relevant.
