Air, water, food. Without those three no life. It’s simple as that. And there is a reason water stands in the middle. Look at the latest space adventures. We want to go to Mars, we are talking about settlers or Mars and we look desperately for water. Any sign of water. Water will bring air and food. With a lot of help but it is achievable. Any planet with signs of water means life.

About 71 percent of the Earth's surface is water-covered and up to 60 percent of the human adult body is water. The human brain and heart are composed of 73 percent water, and the lungs are about 83 percent water. The skin contains 64 percent water, muscles and kidneys are 79 percent, and even the bones are watery: 31 percent. Each day humans must consume a certain amount of water to survive. Of course, this varies according to age and gender, and also by where someone lives. Generally, an adult male needs about 3 litters per day while an adult female needs about 2.2 litters per day. Some of this water is gotten in food.

Water serves a number of essential functions to keep us all going:

- A vital nutrient to the life of every cell, acts first as a building material.

- It regulates our internal body temperature by sweating and respiration

- The carbohydrates and proteins that our bodies use as food are metabolized and transported by water in the bloodstream;

- It assists in flushing waste mainly through urination, acts as a shock absorber for brain, spinal cord, and foetus forms saliva. Lubricates joints

Water is the essence of life but while we are looking for water in Mars there are humans dying on Earth lacking clean water or poisoned from water. Let’s get back to numbers.

- 783 million people - 1 in 10 of the world’s population - lack access to safe water.

- Globally, 1/3 of all schools lack access to safe water and adequate sanitation.

- 2.4 billion people - 1 in 3 of the world’s population - lack access to a toilet.

- 6 to 8 million people die annually from the consequences of disasters and water-related diseases.

- An estimated 801,000 children younger than 5 years of age perish from diarrhoea each year, mostly in developing countries. This amounts to 11 percent of the 7.6 million deaths of children under the age of five and means that about 2,200 children are dying every day as a result of diarrheal diseases.

- Unsafe drinking water, inadequate availability of water for hygiene, and lack of access to sanitation together contribute to about 88% of deaths from diarrheal diseases.

- Due to global warming water availability is expected to decrease in many regions. Yet future global agricultural water consumption alone is estimated to increase by around 19percent by 2050, and will be even greater in the absence of any technological progress or policy intervention.

Personally I was lost somewhere in the fact that 2,200 children younger than 5 die every single day because they lack clean drinkable water.

Air is free. Polluted or not, there is everywhere. Food is most of the time result of an exchange. I grow, I eat. I work, I make money, and I buy food. Water despite its necessity is in a limbo. Clean, drinkable water is not everywhere in nature despite the fact that our planet is consisted – at least in the surface – by 71 percent. Actually while 39 countries control nearly 90 percent of the clean water with water basins in their land, 21 countries have no access to drinkable water at all.

Unfortunately these last numbers hide a tragic reality. They hide conflict, political blackmails, geopolitical games, they hide wars and death, private interests, private companies and profit. The excuse? Clean water needs money to be clean. The result? 2,200 children younger than 5 dead every single day; 6 to 8 million people annually.

Water management is one of the answers but not in the hands of the private sector. Nobody can allow a matter of life and death in the hands of profiteers. This is a global matter for water without frontiers under the control of the United Nations, regulated by the UN and funded globally and unquestionably. Any action which will endanger a life or death issue like water it will call for a reaction and reactions over life and death issues never end well.

This is the only way to stop 2,200 children younger than 5, die every single day because they lack clean drinkable water.
