Recent advances in our understanding of star formation and the associated production of heavy elements at high redshift are reviewed. First, the host galaxies of star-formation regions at 2 - 4 redshift are characterized, and a comparison with their local counterparts is made. Then I will summarize the properties of the stellar content in these objects. A major theme is the interaction and feedback between star formation and the dynamical state of the interstellar medium of the host galaxy. Star formation enriches the interstellar medium with chemically processed material and may be able to drive the galaxy ISM into the intergalactic medium via powerful superwinds. The chemical composition of star-forming galaxies at high redshift is compared to abundances derived for damped Lyman-α absorbers and the Lyman-α forest. A consistent scenario for the metal production can be derived if the heavy elements produced in star-forming galaxies leave their formation sites and are effectively dispersed in the universe by a yet to be determined mechanism.
