Why do those people in the church of the Holey Climate Change never stop to think about the plants?

Why do they hate plants so much?
I mean shit, can't they see that plants need CO2?
Why must they deny them the essentials?

Fortunately, one puff from a volcano outputs more CO2 than all the cars put together, so if stingy H.C.C.ers won't provide, the earth will.
