In a conference held in France, a group of scientists made a symbolic designation that holds significant meaning. They officially declared Lake Crawford as the starting point of a new geological epoch, known as the Anthropocene era. This epoch is defined by the profound and far-reaching impact of human activities on our planet.

Lake Crawford, located near the city of Toronto in Canada, is a charming and relatively small body of water with great depth. However, its importance took a dramatic turn when scientists symbolically identified it as the epicenter of the early Anthropocene era.

Remarkable characteristics of the Crawford Lake

Out of 11 potential sites, Crawford Lake stood out as the chosen location due to its remarkable characteristics. This lake boasts a depth of 29 meters and spans an impressive area of 24,000 square meters.

The decision to select Crawford Lake was primarily driven by its exceptional preservation of the yearly impacts of human activity on the Earth’s soil, atmosphere, and biology. These impacts are vividly recorded within the layers of sediment found in the lake.

The sediments found within Crawford Lake serve as a compelling reflection of our changing era. These sediment layers bear witness to various forms of debris associated with human activities such as pollution, fuel combustion, fertilizer utilization, and pesticide application.

They stand as undeniable evidence of mankind’s immense influence, positioning us as one of the most significant geological forces shaping our planet.

Anthropocene era time period

Referred to as the Anthropocene era, a term derived from the Greek words for “human” and “new,” this epoch is believed to have commenced between the years 1950 and 1954, as determined by the scientific community.

This places the influence of humans in a comparable category to the catastrophic meteorite impact that occurred approximately 66 million years ago. This event led to the extinction of dinosaurs and marked the beginning of the Cenozoic Era, also known as the “age of mammals.”

However, it is important to note that the power of human impact, while significant, does not precisely parallel the magnitude of that ancient event.

New geological era after a meteorite impact

While the meteorite impact initiated an entirely new geological era, the collective findings and conclusions of the scientific working group indicate that the influence of humans has led to the establishment of a more modest geological epoch. This epoch represents a relatively smaller span of geological time.

Geologists employ various units to measure time, including eons, eras, periods, epochs, and ages. The scientific working group proposes that the Anthropocene Epoch, following the Holocene Epoch, emerged after the conclusion of the ice age approximately 11,700 years ago.
