This is a 3 (30 min) part documentary following the movement of one carbon atom's life.. it teaches you every detail of why our usage of oil is so alarming - and if you're a thinker, will start you considering the ramifications of the use of other fossil fuels such as uranium, and just how unknown their impacts may be.

ABC host this series on a server where you can watch them streaming with no lag or buffering time.. if you're on iinet, I believe it's not even metered.
I credit this show for my entire understanding of the oil problem.. it's brilliant.
