# Big History and Environmental History History I · Thinking History · https://tryals.app/learn/history-i/big-history-and-environmental-history ## Widening the Frame Every scale of history is a choice about causes. **Big History** spans 13.8 billion years from the Big Bang, focusing on complexity and energy. **Environmental history** makes climate, soil, and disease active participants rather than mere scenery. Consider why Eurasia conquered the Americas. **Eurasia runs east-west**, letting crops and animals spread along matching climates. **The Americas and Africa run north-south**, blocking diffusion across climate zones. | Factor | Consequence | | --- | --- | | East-west axis | Crops spread easily | | Herd animals | Zoonotic disease | | No livestock | Zero immunity | Centuries of living near animals bred smallpox and measles. This caused **50-90% mortality** in the Americas, with most dying before Europeans even arrived. ## Climate as Actor and the Determinism Trap Climate data reveals history's hidden drivers. The **Little Ice Age** (1300-1850) brought global harvest failures. The 1815 **Tambora** eruption caused the year without a summer, while the **Black Death** (1347-51) killed up to half of Europe and broke western serfdom. The core charge against this view is **determinism**: if geography explains everything, human agency vanishes. But environmental factors merely set the **field of possibility**. **Disease enabled the conquest; it did not dictate the slave trade or mines.** Widening the frame does not remove responsibility; it locates agency where it actually operated. ## Practice questions 10 of this lesson's 14 practice questions, with answers. The full set is in the app. ### 1. What does widening the frame to environmental and deep time actually buy a historian? A. Questions unanswerable at conventional scale become tractable B. Climate, disease, and animals can be treated as causes rather than scenery C. It establishes that human choices were never historically decisive D. It shows at which speed a given cause operates, locating agency precisely **Answer:** A. Questions unanswerable at conventional scale become tractable; B. Climate, disease, and animals can be treated as causes rather than scenery; D. It shows at which speed a given cause operates, locating agency precisely **Why:** Tractability, new causes, and precision about scale, this is Braudel’s question in different clothes. the third option is the failure mode, not the payoff.

How did the Black Death reorganize western European society? A. It triggered the collapse of long-distance trade for two centuries B. Labour scarcity strengthened peasants and helped break serfdom C. It concentrated land in the hands of lords and deepened serfdom D. It had no measurable economic effects beyond the mortality itself **Answer:** B. Labour scarcity strengthened peasants and helped break serfdom **Why:** Kill half the workers and the survivors can name a price, which they did, over furious legislative resistance. A pathogen with no interest in politics did more for peasant bargaining power than any revolt of the era.

Complete the honest formulation. **Answer:** Eurasia’s east–west **axis** let domesticates spread along one climate band, producing dense populations, herd animals, and the **zoonotic disease** that gave Eurasians endemic immunity and devastated the Americas. But environment sets the field of possibility; the encomienda, the mines, and the slave trade were **decisions** made by people who had alternatives. **Why:** Axis, disease, decisions. Widening the frame is not a way of relieving anyone of responsibility, it is how you find out where the responsibility actually sits.

Why does a continent’s east–west axis matter for the diffusion of crops and animals? A. Rivers on east–west continents run in the direction of travel B. East–west routes are shorter than north–south routes C. Domesticates spread along a shared latitude and climate band D. Prevailing winds blow east–west across all continents **Answer:** C. Domesticates spread along a shared latitude and climate band **Why:** Crops track latitude, day length and temperature. Eurasia’s east–west span let a domesticate travel thousands of kilometres inside one band; the Americas and Africa force every diffusion through climate zones that kill it.

Why did Eurasian populations carry epidemic diseases that American populations did not? A. European urban filth and poor sanitation alone B. Ships’ rats carrying pathogens across the Atlantic C. Millennia of living beside domesticated herd animals D. Deliberate biological warfare from the first contact onward **Answer:** C. Millennia of living beside domesticated herd animals **Why:** They are zoonoses: the price Eurasia paid for cattle, pigs, and horses was millennia of livestock disease crossing over, and the immunity that came with surviving it. The Americas had almost no herd domesticates and therefore no exposure.

The majority of epidemic deaths in the Americas occurred after sustained European settlement, as a direct consequence of military campaigns. **Answer:** False **Why:** Disease ran ahead of the conquerors along indigenous trade networks, a large share of the dead never saw a European. Estimates run to 50–90% mortality within a century and a half, a scale that makes every battle of the conquest a rounding error.

Match each environmental event to its historical consequence. **Answer:** - Black Death (1347–51) → Wages rose and western serfdom lost its grip - Little Ice Age (~1300–1850) → Harvest failure and revolt in the seventeenth-century general crisis - Tambora eruption (1815) → The year without a summer: famine and migration in 1816 - Eurasian herd domesticates → Zoonotic epidemics, and the immunity of surviving them **Why:** A pandemic that raised wages, a cold snap that toppled states, a volcano that starved New England, and the livestock that armed a hemisphere without anyone intending it.

Environmental history relies on pollen cores, ice cores and tree rings. What did admitting these as sources change about the discipline? A. It made history a branch of the natural sciences B. It replaced documentary evidence, which was found to be unreliable C. It extended history into periods with no documents at all D. It confirmed environmental determinism, since natural data drives the accounts **Answer:** C. It extended history into periods with no documents at all **Why:** A bog records the vegetation of a valley for ten thousand years with no scribe involved, so the past becomes legible where writing never reached. Option 4 inverts it: the same data has been used to *refute* determinist claims, by showing societies responding differently to identical climate events.

Sort each item: was it set by the **environmental field of possibility**, or was it a **human decision**? **Answer:** - Field of possibility: Which populations carried smallpox and which had no immunity, Which continent’s crops could diffuse without crossing climate zones - Human decision: The encomienda system of forced indigenous labour, The transatlantic slave trade **Why:** Geography decided who arrived carrying which pathogens. It did not decide the encomienda, the mines, or the slave trade, those were made by people with names who had alternatives. Widening the frame locates agency; it does not dissolve it.

What is the central criticism of environmentally determinist accounts such as _Guns, Germs, and Steel_? A. Inevitability quietly excuses what people chose to do B. They apply only to the Americas and nowhere else C. They rely on climate data that has since been disproved D. They ignore the role of disease in historical change **Answer:** A. Inevitability quietly excuses what people chose to do **Why:** The framework handles the continental pattern well and specific decisions badly, and when it slips, conquest becomes something that _happened_ rather than something that was _done_. That slide is the objection, and it has force. Page: https://tryals.app/practice/history-i/big-history-and-environmental-history/what-is-the-central-criticism-of-environmentally-determinist-accounts
