"Considering these and many other major and still growing impacts of human activities on Earth and atmosphere, and at all, including global, scales, it seems to me more than appropriate to emphasize the central role of mankind in geology and ecology by proposing to use the term 'Anthropocene' for the current geological epoch."

— from The 'Anthropocene', 2000

"For the past three centuries, the effects of humans on the global environment have escalated. Because of these, it seems to me that it is more than appropriate to emphasize the central role of mankind in geology and ecology by proposing to use the term 'Anthropocene' for the current geological epoch."
