So with all this carbon constantly being depleted from the atmosphere, we really need to keep carbon output up to a certain point.
So why all the bad press for burning carbon?
Well, turns out it's the source of the carbon being burned that's the key.
It's in fact the burning of what we call "fossil carbon" that creates the imbalance.
Fossil fuels, coal, oil, natural gas, these substances are all mined, we have to dig them up or drill a well to release them.
-And this is carbon that was in the atmosphere millions of years ago.
So what happens is: when we burn this carbon, OK, it doesn't really release a whole lot compared to the amount that's already there in the atmosphere, but it adds to the pool.
-And over years it accumulates, think of the atmosphere as a big bathtub.
It's basically already filled to the brim with carbon, when we start adding fossil carbon into the mix, it starts to spill over.
That being said, there's actually a category that's in-between: what we call biomass fuels, probably the most common one is wood.
