Why do some animals live in groups?
You've seen flocks of birds swirling through the sky like ~~living clouds~~, herds of zebras thundering across the plain

You've seen flocks of birds swirling through the sky like living clouds, herds of zebras thundering across the plains, schools of fish turning all at once as if they share one brain. Why don't these animals just live alone, doing their own thing? Turns out, there's a pretty good reason: living together keeps you alive.

First big reason: more eyes watching for danger. Imagine you're a meerkat standing guard in the Kalahari Desert. One meerkat can watch maybe a quarter of the horizon. But ten meerkats? Now you've got lookouts in every direction. While some eat breakfast, others scan the sky for eagles. The second a hawk appears, someone squeaks the alarm and everyone dives for the burrow. Nobody gets surprised.
