How Humans and Elephant Seals Use and Need Water
1. Why is water considered a "Natural Resource?"
2. How is water essential (required) to our survival and the survival of all living things?
1. Water is considered a natural resource because nature produces it. Humans can't make water unless it is already there. So it is natural.
2. Water provides hydration, which means that it keeps us from dying of dehydration. Without water, many people would die, and our population would decrease by a lot.
