Ernst Haeckel, ancient forests, and the Anthropocene.

Area of Science:

• Historical environmental science
• Geological time concepts
• History of science

Background:

• This addendum revisits Ernst Haeckel's early concept of the "Anthropozoic Age" (1868), a 19th-century precursor to the modern
• Anthropocene" epoch, coinciding with the centenary of his death.
• Haeckel's work was influenced by 19th-century Romantic-era writers, including Alexander von Humboldt, Antonio Stoppani, and George P. Marsh.

Discussion:

• George P. Marsh extensively detailed human impact on natural ecosystems, especially forests, from the 1840s onwards.
• Marsh and Haeckel independently described extensive planetary remodeling by humans, coining the term "Anthropozoic Age" to characterize this human-dominated era.
• The concept highlights a long-standing awareness of significant anthropogenic environmental change.

Key Insights:

• Ernst Haeckel was an early proponent of the "Anthropozoic Age," a term anticipating the "Anthropocene."
• George P. Marsh provided detailed accounts of human-induced environmental destruction, particularly deforestation, in the mid-19th century.
• Both Marsh and Haeckel recognized and articulated the profound human influence on the planet's geology and ecosystems.

Outlook:

• Re-evaluating historical concepts like the "Anthropozoic Age" enriches our understanding of the Anthropocene's intellectual origins.
• Recognizing the historical depth of human impact underscores the urgency of addressing contemporary environmental challenges.
• Further research into 19th-century environmental thought can reveal more precursors to current scientific paradigms.
