Sea water and life under threat....:crying:

The disturbing truth is that humans are having unrecognized impacts on every part of the ocean, and there is much we have not seen that will disappear before we ever get a chance......

We need to fish less and in less destructive measures, waste less, pollute less and protect more....

Turn Salt Water Into Drinking Water....Feeling thirsty and all you have is salt water? Well, no problem. Turn it into drinking water.

Drinking seawater can be deadly to humans

Deployment of a CTD rosette
One of the instruments scientists can use to measure salinity is a CTD rosette, which measures the Conductivity (salinity), Temperature, and Depth of the water column.

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. Additionally, when we consume salt as part of our daily diets, we also drink liquids, which help to dilute the salt and keep it at a healthy level. Living cells do depend on sodium chloride (salt) to maintain the body’s chemical balances and reactions; however, too much sodium can be deadly.

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.
