Day 315 – About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water. The remaining water is found in water vapor, in rivers and lakes, in icecaps and glaciers. When you consider how much water is drinkable you are down to 1 percent. That is not much water for over 7.9 billion people.
So, why can’t we drink ocean water?
“Seawater contains salt. When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body. Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier.” – National Oceanic and Atmospheric Administration
Thankfully, there are NGOs (non-governmental organizations) like GivePower that are trying to address the issue of unsafe drinking water.
“Their most recent success story is related to Kenya and the village named Kiunga, where they managed to install a solar-powered desalination system. This system transforms ocean water into drinkable water and can produce enough water for 35 000 people per day (around 70 thousand liters). Before Give Power, the inhabitants of Kiunga had to travel one hour each day to reach a water source, but it was one used also by animals and full of parasites. Such improvements, like Give Power’s initiative, are constantly needed as according to the World Health Organization, there are still 2.2 billion people around the world who do not have access to drinking water and 4.2 billion can’t access safely managed sanitation services.” – Goods Home Design
