Anthropocene Debate Flashcards
(12 cards)
What is the Anthropocene?
A proposed geological epoch where humans have significantly altered Earth’s systems, especially climate, beyond Holocene variability
What evidence supports early agriculture influencing climate?
CO2 increases from deforestation
Methane from rice farming / livestock, ~5,000 years ago
What is the ‘Orbis Hypothesis’?
1610
A theory that forest regrowth in the Americas after Indigenous depopulation due to colonisation.
Because Indigenous people were not farming or managing the land
Caused a CO2 drop, leaving a geological marker in Antarctic Ice records, marking the start of the Anthropocene
Why might 1492 be considered the start of the Anthropocene?
Due to European colonisation, mass deaths, land abandonment, global trade and resulting ecological changes
What are other possible start points for the Anthropocene?
Early agriculture ~10,000 years ago
European colonisation ~1500
Industrial revolution ~1750
Great acceleration ~1945
What marks the great acceleration in the Anthropocene timeline?
Post WWII surge in population, fossil fuel use, industrial agriculture and globalised trade
What are the geological indicators used to date the Anthropocene?
Ice and sediment cores
Carbon isotopes
Extinction events
Why do people argue the Anthropocene began with agriculture?
Agriculture caused large scale land use changes, early CO2 and methane emissions
What impact did the Silk Road and early empires have on the Earth system?
Spread of crops, technology and trade networks that began shaping global food systems and ecological footprints
How is the Anthropocene linked to global inequality?
Those who contributed the least (global south, indigenous communities) often face the worst effects, while the wealthiest emit the most
Why do some resist using the term Anthropocene?
It generalises responsibility to ‘humanity’ without recognising that not all humans equally contributed to environmental damage
Whereas, Capitalocene argues capitalism and economic systems are the true root cause
What role did technological innovations play in triggering the Anthropocene?
Tools like ploughing, irrigation, fossil fuelled machines
Enables exponential resource extraction and landscape transformation
