- IDEA 1 OF 8
Societies choose to fail or survive
Diamond studies why some societies collapsed while others survived.
He argues that collapse is not inevitable, because the choices societies make about their environment and their neighbours often decide their fate.
- IDEA 2 OF 8
Five factors explain collapse
Diamond proposes a framework of five factors: environmental damage, climate change, hostile neighbours, loss of trading partners and a society's response to its problems.
The last factor, he argues, is often the most important.
- IDEA 3 OF 8
Easter Island lost its forests
Diamond describes how the people of Easter Island cut down their forests, partly to move giant statues.
Without trees, they lost resources for boats, fuel and farming. Its decline was a warning.
- IDEA 4 OF 8
The Norse failed in Greenland
Diamond describes how Norse settlers in Greenland held on to European farming ways that did not suit the harsh environment.
Unlike the Inuit, they failed to adapt and eventually disappeared.
- IDEA 5 OF 8
The Maya faced many pressures
Diamond argues that the Classic Maya collapse involved deforestation, drought, warfare and leaders who focused on short-term goals.
These pressures combined to destroy cities. Elites ignored warning signs. Short-term thinking proved fatal.
- IDEA 6 OF 8
Rwanda's tragedy had environmental roots
Diamond discusses how population pressure and land scarcity contributed to tensions in Rwanda before the genocide.
He presents this as one factor among many. Scarcity can fuel conflict. It was one cause.
- IDEA 7 OF 8
Neighbours can take different paths
Diamond compares Haiti and the Dominican Republic, which share an island.
Different choices about forests and governance led to very different outcomes. Choices made a difference. One island, two fates.
- IDEA 8 OF 8
Some societies succeeded
Diamond describes societies that managed their environments well, such as Tokugawa Japan, which protected its forests.
He argues that modern societies can learn from these examples. Good choices can prevent disaster.
