Water is one of the most important (1) natural resources on Earth. We need fresh water to drink, and we need it to grow and cook food, and to wash. Plants, animals, and people all need water to (2) live. About 70% of Earth is (3) covered with water, but most of this water is saltwater in oceans. People need fresh water to drink, but only about 3% of Earth's water is (4) fresh. In some countries, there isn't enough water. Sometimes, people have to travel a long way to (5) collect water, or they move to a new place where there is water.
