Water is life. It’s a fundamental need for every human being on the planet. Each person requires more than five gallons of clean and safe water a day for drinking, cooking, and keeping clean. Dirty water, on the other hand, can be deadly. An estimated 1.8 million people die every year as a result of diarrheal diseases like cholera. And tens of millions of people are seriously sickened by water-related maladies.
Augmenting food with preservatives is not a recent practice. For thousands of years, we have canned fruits with sugar, preserved meats with salt, and pickled vegetables so that they could keep in hot humid environments.
