The symbol above represents extinction. The circle signifies the planet, while the hourglass inside serves as a warning that time is rapidly running out for many species. The world is currently undergoing a mass extinction event, and this symbol is intended to help raise awareness of the urgent need for change in order to address this crisis. Estimates are that somewhere between 30,000 and 140,000  species are becoming extinct every year in what scientists have named the Holocene, or Sixth Mass Extinction. This ongoing process of destruction is being caused by the impact of human activity. Within the next few decades approximately 50% of all species that now exist will have become extinct. Such a catastrophic loss of biodiversity is highly likely to cause widespread ecosystem collapse and consequently render the planet uninhabitable for humans.

In order to spread the message as widely as possible, please create this symbol in any location you feel able to. Thank you.

Please note: In response to several companies attempting to use the symbol on their mass-produced clothing/giftware products, the following clarification is now made:
The extinction symbol is a not-for-profit participatory project. The creation and free use of the extinction symbol by individuals in their personal artwork or other forms of expression is strongly welcomed and encouraged, but any form of commercial use of the symbol is completely against its ethos and should therefore be refrained from. Thank you.
