The Ginkgos
The Ginkgos

Ginkgoes are often planted in cities not only because they're pretty trees but also because they thrive where air pollution is bad. It's not surprising that ginkgoes are air-pollution tolerant, because they are very primitive plants; they may have evolved when the earth's atmosphere was even more sulphurous and grimy than today, because of erupting volcanoes. In fact, ginkgoes are living fossils.
