The Unextinction Machine is excited by the Extinction Symbol. This is an hourglass inside a circle representing Earth. The symbol is available for anyone to use and reproduce anywhere (with an Attribution and Non-commercial license) to raise awareness of the Mass Extinction Event we are undergoing. 30,000 to 130,000 species are becoming extinct each year. Extinction of too many species will cause ecosystem collapse. Humans depend on biodiversity. Share it, and the news.
