Carbon Sources Harmful?

Narrator: Baabob, did you know that carbon sources can be harmful?
Baabob: Really! Then I will never breathe again!
Narrator: Uh... Baabob...
Baabob: You lie!
--Slap--
Narrator: Anyway, carbon sources can be harmful because they add carbon dioxide to the air, which contributes to global warming.
Baabob: Carbon bad! Die, you Carbon!
Narrator: Baabob, we still need carbon in our atmosphere if we want to live.
Baabob: We need bad stuff?
Narrator: Yes Baabob. Still, carbon sources are also bad because there is less oxygen for us to breathe, due to the halting of photosynthesis.
