Whater Footprint

A water footprint is the amount of water a person consumes each day. However, it's not aso simple as calculating the amount of water you drink or use to wash with. Your water footprint"is the amount of water that you consume by your way of life. It includes the water that is used to make your clothes, the food you eat, and any other products you consume.

Everywhere around the world people use water daily, but not everyone has access to clean water. The world's water supply is under pressure from a growing population. Already, 1.2 billion people, about a fifth of the world's population, are living in areas where water is scarce. And many people in the rest of the world use more water than they need which adds to the problem of water shortages.

So what can you do to reduce your water footprint? First, try changing some bad habits you have like taking a shower instead of a bath or turning off the tap while brushing your teeth. Another important way to reduce water waste is not to waste food. By eating all the food you buy, you help make the most of the water used to produce it. The less food you waste, the less water you waste. Finally, you should be aware of what foods and other products require a lot of water to produce and make smart consumer choices. Knowing your water footprint and making an effort to reduce it can really make a difference.
