The article discusses the possibility of Earth entering a new epoch called the Anthropocene, which would be defined by significant planetary changes caused by human activities. The Anthropocene Working Group (AWG) has selected Crawford Lake in Canada as the site with the best geological evidence for this new epoch. Plutonium isotopes from nuclear weapons fallout at the bottom of the lake date the start of the Anthropocene to the early 1950s. However, there is disagreement among researchers about whether the Anthropocene should be defined as a geological epoch or an ongoing event. The proposal will undergo further rounds of voting before it is officially added to the geological timescale. [Extracted from the article]
