The Earth is divided into geological time scales, each denoting events that occurred in Earth’s geological history, by scientists. The scale begins with the formation of the Earth about 4.5 billion years ago, known as “Hadean”. The current geological epoch is known as the “Holocene”, which began approximately 11,700 years ago. The Holocene epoch is characterized by the rapid proliferation and spread of the human species on Earth. The “Anthropocene” is a proposed epoch that follows the Holocene and marks the period when human activity has started to have a significant impact on the planet’s ecosystem. The term “Anthropocene” was first proposed by the Dutch chemist Paul J. Crutzen and American biologist Eugene F. Stoermer (Crutzen & Stoermer 2000) to denote the current period in Earth’s geological history wherein, instead of the environment shaping humans it is the humans who are shaping and drastically altering the environment.
The Anthropocene, according to Steffen et al. is divided into three periods (616). It begins with the industrial revolution, wherein man first harnessed the energy of fossil fuels, coal, and oil and gas. The extensive use of the newfound wealth of energy in the form of fossil fuels stamped a significant imprint on Earth’s environment, evident in the increase in deforestation and rise in the concentration of methane, carbon dioxide, and nitrous oxide in Earth’s atmosphere (616). The second period, from 1945-to 2015, is known as the “great acceleration”. This period is characterized by an exponential increase in the impact of humans on the Earth system. An increase in the population of humans and an increase in industrialization resulted in a substantial increase in the concentration of greenhouse gases in Earth’s atmosphere (618). The third period, from 2015 onwards, is known as “stewards of Earth’s system”. This period is marked by the recognition of Anthropogenic influences on the Earth system and the subsequent filtration of this growing awareness on decision-making processes (618).
The major problem represented by the Anthropocene is the radical shifts in Earth’s temperature and biodiversity. These shift include global warming, extinction of species, habitat loss, and changes in the chemical composition of oceans and soils. Other probelms inlclude sustenance of human vices like greed, indifference, and intemperance.
There are, according to Steffen et al., three philosophical approaches to dealing with these problems. Firstly, is the business-as-usual philosophy (619), which employs a laissez-faire mindset when dealing with the changing global environment. The second is mitigation which is “based on the recognition that the threat of further global change is serious enough that it must be dealt with proactively” (619). And the third option is geoengineering (619), which attempts to solve the problem of climate change with technology.
