I comment on primordial abundances, their implications for cosmic baryon density (all are consistent with 4 ≤ η10 ≤ 5), the nature of baryonic dark matter (probably mainly hot intergalactic gas), its metallicity and implications for the overall yield. Recent estimates of the cosmic star formation rate as a function of red-shift are discussed in the light of the present-day densities of stars and heavy elements.
