Discussed herein are the Earth atmosphere processes dealing with space dust which allow us to regard it as an ecological factor. The estimates of the space dust flux density to the Earth obtained by various methods are presented. The spread of their values is large enough: from 0.1 to 60,000 tons per year. Keywords: space dust, meteoroids, atmosphere, ecology. DOI: 10.25791/esip.11.2025.1553 Pp. 03-12.
