A realistic extension of the electroweak model is proposed in which electroweak magnetic monopoles and Z-strings appear as topological defects. The ensuing cosmology is discussed and it is pointed out that electroweak strings and, more generally, light superconducting strings may yield a significant flux of antiprotons in our galaxy.
