# Everything is Connected

> An encyclopedia of connections: how is X connected to Y? Each page explains a surprising pair — step by step, through a network of entities and relations.

Each page answers one question — how is X connected to Y? — and derives the answer through Benedikt Müller's relations model (entities, relations, three states, network levels). The model itself is documented on the sister site.

## Connections
- [How is coffee connected to climate change?](https://everything-is-connected.info/en/connections/coffee-and-climate-change): Coffee and climate change are closely linked, in both directions. Coffee only grows well in a narrow band of warmth and rain near the equator. As the world heats up, that band is shrinking, so growing coffee gets harder and prices go up. At the same time, clearing forests for new plantations adds to the warming. Your cup and the planet's weather sit on the same chain.
- [How is sleep connected to the economy?](https://everything-is-connected.info/en/connections/sleep-and-the-economy): Sleep and the economy are tightly linked. Rested people focus better, make fewer mistakes and stay healthier, so they work better. When work culture eats into sleep, it flips: productivity falls, accidents, sick days and health costs rise and drag whole economies down — researchers estimate the loss at hundreds of billions of dollars a year. Your night's rest quietly powers the day's work.
- [How are octopuses connected to the World Cup?](https://everything-is-connected.info/en/connections/octopuses-and-the-world-cup): Octopuses and the football World Cup are linked through a remarkable phenomenon: ever since Paul the Octopus correctly 'predicted' eight consecutive World Cup matches in 2010, media worldwide have used animals as oracles. Behind it is not clairvoyance but the interplay of chance, human pattern-seeking and real animal intelligence — a chain connecting marine biology, mass media and global sport.
