📖 Reading Passage

The concept of the 'Anthropocene' has gained traction among geologists as a proposed new geological epoch defined by significant human impact on Earth's geology and ecosystems. Unlike prior epochs, which were characterized by natural climatic shifts or biological events, the Anthropocene is marked by human-induced changes such as nuclear fallout, plastic pollution, and accelerated species extinction. Proponents argue that these markers are stratigraphically distinct, warranting formal recognition. However, critics contend that the term oversimplifies complex human-environment interactions and that its start date remains ambiguous, with suggestions ranging from the advent of agriculture to the mid-20th century. This debate highlights broader questions about how scientific classifications reflect societal values and whether they adequately capture the scale of human influence.
