While I do agree that recycling has to be done.........I sometimes feel that we are bombarded with conflicting information that makes choices difficult.

If I remember my O level biology correctly, plants(and trees) remove CO2 and create O2 when they are in sunlight. When the light level drops below a set amount the process is reversed i.e. they use O2 and create CO2. This was the reason why they say its bad to keep plants in a bedroom.
