1. Only 0.007% of the water on earth is drinkable

Yes, exactly 70% of the water on earth is salt water. This is obviously not suitable for drinking. Only 30% of the earth's water resources are on land. Of this 30% fresh water, only 2.5% is fresh water, of which only 1% is accessible. Large amounts of fresh water reserves are locked up in glaciers. One thing leads to another, so that only 0.007% is drinkable. Hard to believe, right?

2. Where does our water come from?

We sip from groundwater: 61%, or more than half of our drinking water in Germany, is obtained from groundwater. A further 12% is taken from dams and lakes, 9% comes from spring water, enriched groundwater and bank filtration. Only 1% of our drinking water comes from rivers.

3. Tap water is one of the safest foods

Through various treatment processes, the water in the waterworks is made into drinking water and is tested several times before it ends up in your pipes. Just so you know: Tap water is one of the best-controlled foods in Germany. Simply turn on the tap, fill up the soulbottles drinking bottle , and you're done. The drinking water regulations guarantee perfect water. The transmission of diseases and viruses is almost impossible. However, you are responsible for the house connection yourself.

4. Virtual water consumption pollutes the environment

On average, a person in Germany consumes 123 liters of water per day: for drinking, cooking, washing, and personal hygiene. This does not include the so-called virtual water consumption - the water needed to produce food, clothing, and other consumer goods. About 140 liters of water are needed for a cup of coffee, and more than 1,000 liters are needed to produce 1 kg of avocado. Would you have thought that?

5. Drinking tap water is good for the climate

On average, 202.74 g of CO₂ are produced per liter of bottled water, compared to just 0.35 g for tap water. The high climate impact of mineral water is due to the high costs of transport and packaging. If everyone in Germany switched from mineral to tap water, three million tons of CO₂ could be saved. That's 1.5 times as much CO₂ as if all domestic air traffic in Germany were to be stopped. Would you have thought that?

6. Water is a true prodigy of alchemy

The sun evaporates water into water vapor and then it comes back to earth in liquid form as rain. At low temperatures, water freezes into ice and becomes solid. At geysers, you can watch water change to a gaseous state. And here's the thing: Under certain circumstances, water can freeze, evaporate and remain in liquid form at the same time. This point is called the triple point. Pretty cool.

7. Drinking water makes you smart

The human body is made up of 80% water, and blood is 90% water. Around 2.5 liters of water are excreted through the kidneys, skin and lungs every day. To compensate for this loss of fluid, it is important that you drink water regularly. If you haven't drunk anything for a long time, the blood thickens and flows more slowly. As a result, the brain suffers from a lack of oxygen and you can no longer concentrate.
