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 previous epochs, which were characterized by natural climatic shifts and biological evolution, the Anthropocene is marked by human-induced changes such as nuclear fallout, plastic pollution, and accelerated species extinction. However, the formal recognition of this epoch remains contentious. Critics argue that human activity has been altering the environment for millennia, making it difficult to pinpoint a precise starting point. Proponents suggest the mid-20th century, coinciding with the 'Great Acceleration' of industrial growth and global-scale impacts, as the most appropriate boundary. This debate highlights broader questions about how humanity's legacy will be preserved in the geological record and whether our species' influence warrants a distinct stratigraphic designation.
❓ Según el pasaje, ¿por qué es controvertido el reconocimiento formal del Antropoceno?
A. A) Porque el impacto humano en el medio ambiente ha sido relativamente menor en comparación con los cambios naturales.
B. B) Porque existe desacuerdo sobre cuándo la influencia humana comenzó a definir una época geológica distinta.
C. C) Porque la lluvia radiactiva y la contaminación por plásticos no se consideran marcadores geológicos duraderos.
D. D) Porque el concepto de Antropoceno carece de apoyo por parte de la comunidad científica.
✅ 正确答案
B) Because there is disagreement over when human influence began to define a distinct geological epoch.
