Abstract: Observations of local galaxy I Zw 18 imply that the dust mass in star-forming, metal-poor environments is much lower than expected, and, therefore, that the amount of dust in young galaxies of the early Universe, such as redshift-6.6 galaxy Himiko, is probably a factor of about 100 less than previously thought.
