Is the human race heading for a mass extinction event?
A cartoon showing geological rock strata and fossils, including the iridium layer that appeared at the time of the mass extinction of the dinosaurs.
The rock strata also include a layer of manufactured waste that is directly above the layer of rock that contains fossils of humans
The implication is that while the event that created the iridium layer destroyed the dinosaurs, the event that created the layer of anthropogenic waste destroyed the human race.
The current geological era or epoch is sometimes referred to as the anthropocene, as the major influence on the environment is the human race.
An earlier version of this cartoon appeared in my book of environmental cartoons, When Humans Roamed the Earth, published by Earthscan/WWF in 1991
