Some people in the world have safe water to drink. Around 800 million people have no safe water to drink. Some people can normally buy water in a plastic bottle. Bottled water is the most popular drink in the US.

This water is not better than water from a tap. It is much more expensive. It is much worse for the natural world.

Companies need three liters of water to make one liter of bottled water. They also must burn oil to make the bottles. Bottled water needs much more energy than water from a tap.

Difficult words: bottled (in a bottle), popular (something that many people like), tap (a device through which water comes in homes).
