Carbon carbon carbon. Why would anyone dislike carbon? Plant food, an element worth its weight especially to plants.
Not just plants but almost all life, humans included, are built from carbon recently extracted from the trace CO2 in the air. Humans are 18% atmospheric carbon, although plants do the carbon capture for us.
Carbon dating works because free CO2 in the atmosphere is hit by cosmic rays turning some of it into radioactive carbon-14. The ratio of decaying radioactive carbon in something tells roughly how recently it was alive.
