How humans and seahorses 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. A natural resource is a resource that we use that is naturally on Earth. We use water and it is naturally on Earth so it is a Natural Resource.
2. We drink water and without it, we wouldn't be able to survive. Other living things often either use it to drink like us, or to breathe in.
