Life on this planet can be seen simply as a seemingly endless variation of carbon compounds. Biomass is basically a dispersion of carbonaceous matter in water—upon dehydration, about 45% of it, a share much higher than that of any other element, is carbon. Even in the biosphere taken as a whole, with its enormous stores of ocean water, carbon accounts for one-quarter of all atoms and shares second place with oxygen (hydrogen atoms are, obviously, most abundant).
