It is believed that the Earth is currently in the Holocene Epoch, which started around 10,000 years ago when the last glacial period ended. However, scientists believe the Earth may have entered a new epoch called the Anthropocene Epoch. The Anthropocene Epoch is described as a geological time interval characterised by changes in the Earth’s eco-system due to the influence of human activities— such as the use of the Earth’s resources, pollution and deforestation.
For many years, the Anthropocene Working Group (AWG), a group of geologists, has been carrying out studies to determine if the impact of human activities on the Earth is significant enough to be able to include the Anthropocene Epoch as a distinct geological period in the Earth’s timescale. According to evaluations by the AWG, the Anthropocene Epoch started in the 1950s. During this period, there has been a significant increase in plastic pollution, radioactive material, deforestation, emission of greenhouse gases and other effects of human activities on nature.
Crawford Lake in Canada has provided geologists with evidence of the impact human activities have had on the Earth. Examinations of the layered sediments at the bottom of the lake reveal traces of fossil fuel combustion, nuclear material from weapons, plastic and other materials. This is a crucial development in the inclusion of the Anthropocene Epoch in the Earth’s official timeline. However, there are disagreements among scientists regarding the commencement of the epoch and the proof that supports its commencement.
Nevertheless, these findings mark a new chapter in the planet’s history as the impact of human actions on the environment is evident and indelible. Entering the Anthropocene Epoch also emphasises the need for humans to act responsibly and protect Mother Earth.
