Saving water is important as water resources are decreasing around the world. Some ways to save water include brushing teeth with a cup of water instead of leaving the tap running, taking quick showers instead of baths to use less water, turning off the tap while washing hands and only using a small stream of water, tightening taps to prevent leaks, and using water-saving programs on appliances like washing machines and dishwashers. These small changes can help save thousands of liters of water per year.
