Hello there!
Hinting, fishing, making houses, etc.
People can adapt, and use the resourses in the location easily.
If someone where is a heavily wooded area they can make spears out of rock and sticks, they can make tree houses for saftey, etc
If someone where to be in a desert they would have to use cactus for water, and they could use brushes for shelter or even blankets sometimes.
If someone where to be in an Antartic biome the best way to survive is to find loose wood to start fires or use random items that one person would already have.
