2. Plants and animals need water. If there was no water, there would be no fish, and sea animals are a big part of our diet. Animals require water, just like we do. Also, plants wouldn't stay alive for very long. (with the exceptions of cacti and a few others)
3. We need to recycle water to keep it reusable. If we recycle water we can reuse it, therefore not needing to take more water away from the ocean. Water needs to be recycled and we need to keep it in our lives. We also need the power plants that clean the water because without them we couldn't and wouldn't be able to drink water, or even use it at all.
4. Water is interesting because it can change into different forms and has many different, small unnoticed facts about it. Water can take the shape of what it is in. Also, water is interesting to learn about because, with learning about water, you learn about things that the water does, or what lies in water, OR learn about how WE use water.
5. Water is important for scientists to study because they can find out things that they never knew before! Maybe scientists will discover that water has a magical healing property combined with something else! Who knows what could be discovered!?
