How did the geography affect early humans use of resources

People had to learn to use the land to their advantage. So depending on the type of ground (i. e marshy lands) they had to grow crops that would specifically grow there. You couldnt grow a crop that belonged to dry lands in wet lands. Also, animals, your source of meat could be abundant or very limited. If you lived in lands without many plants you sure as heck wont be finding many herbivores.
