Look at first two paragraphs. Which details provide a clue to the author's point of view about water?
Water is a natural resource that makes life on Earth possible. Nothing can live without it. Around the world, many people are running low on water to meet their needs. People use larger amounts of water for drinking, energy, farming, and industry. These needs influence, or affect, the demand for fresh water. Also, waste from human activities can pollute, or poison, the water in rivers, lakes, and the ocean. This lowers water supplies even more.
It may seem odd that we might run low on water because Earth’s surface is mostly water. Seventy percent of Earth’s surface is covered by oceans. They hold about 97 percent of Earth’s water. However, ocean water is too salty to be useful. People need fresh water. Fortunately, something exists that makes ocean water fresh.
