Antroposeenin

Antroposeenin is a proposed geological epoch dating from the commencement of significant human impact on Earth's geology and ecosystems. The term was popularized by atmospheric chemist Paul Crutzen and ecologist Eugene Stoermer in 2000. While not yet formally recognized by the International Commission on Stratigraphy, the concept suggests that human activities have become a dominant force shaping the planet's physical and biological systems. Evidence cited for the Antroposeenin includes changes in atmospheric composition, widespread land-use alteration, the introduction of invasive species, and the production of novel materials like plastics and concrete. The precise starting point of this epoch is a subject of ongoing debate, with proposed markers ranging from the advent of agriculture to the Industrial Revolution and the mid-20th century "Great Acceleration" of population growth and resource consumption. The Antroposeenin highlights the profound and lasting influence humanity exerts on Earth's geological record, distinguishing it from previous natural geological periods. Understanding this epoch is crucial for comprehending current environmental challenges and future planetary changes.
