Final answer:
Streams are a crucial source of water supply and provide recreational opportunities, and historically enabled transportation, but are not associated with the formation of deserts.
Step-by-step explanation:
Streams impact people's lives in various ways. One significant way they influence us is through water supply, as they are a source of fresh water for domestic, agricultural, and industrial use. Recreation is another important impact, with streams offering opportunities for activities like fishing, boating, and swimming. Streams are an important source of water for drinking and irrigation purposes.
As for transportation, historically streams have been vital for the movement of goods and people, although this is less common now with modern infrastructure. Despite their many benefits, streams are not typically associated with the formation of deserts; instead, their presence usually indicates a viable ecosystem that sustains plant and animal life.
