Notes and bibliography and index, yay!
001-004 silliness about the cost of the elements in your body ... actually the cost of purifying those elements. That can be turned upside down; there are 10 tonnes of CO2 carbon above my 0.7 acres, and another 30 tonnes (est) of carbon in my trees and bushes and grass. A few more tonnes in the wood of my house, and the books on my shelf, call that 10 tonnes, for a total of 50 tonnes for a "home price" of perhaps $500K; $10/kg carbon. For the rest of the elements, dig down, there is plenty of everything, arguably $4.7 trillion dollars worth of elements and compounds.
The reference human is Benedict Cumberbatch, 78 kg, ( 18.5% carbon by weight hence 15 kg, so the limiting element of human existence (carbon) cost of a my-backyard-sourced Cumberbatch is $150. Using a less expensive carbon source (like coal, closing at $340/ton (907 kg) is $0.40 per kilogram, or about $6 per Cumberbatch. Humans add 40 billion tonnes of CO2 to the atmosphere per year, perhaps 11 billion tonnes of carbon, or about one million "carbon-Cumberbatchs" per second.
Personally, I believe one Cumberbatch is ample, and would prefer the atmospheric excess turns into 3000 big trees per second. As I write this, way too many Oregon trees are burning into CO2 instead.
