The world's oceans contain roughly 97% of Earth's water, but surprisingly, they are not the saltiest bodies of water. Instead, some smaller, geographically isolated lakes hold the record for extreme salt concentrations. This fact raises a fascinating question: which water contains more salt?

As the third most plentiful element dissolved in seawater, magnesium is readily available in the world's oceans. So, **does magnesium come from the ocean**? Yes, a significant portion of commercial magnesium has historically been, and continues to be, extracted from this immense natural reservoir.

The average salinity of ocean water is about 3.5%, a concentration far too high for human consumption. This high salt content is the primary reason why is sea water unsafe to drink, leading to serious and potentially fatal health consequences if consumed, even in small quantities.

According to the Centers for Disease Control and Prevention (CDC), foodborne illnesses from raw or undercooked seafood affect thousands of people every year. This statistic highlights the significant risks associated with consuming raw fish directly from the ocean, as it can harbor a variety of pathogens that pose serious health threats.

Over 70% of the Earth's surface is covered by ocean, yet contrary to popular misconception, simply boiling seawater does not make it suitable for cooking. The process concentrates the salt and minerals, leading to unpalatably salty and potentially harmful results.

With an average salinity of about 3.5%, seawater contains a concentration of dissolved salts that is dangerously high for human consumption. While a small, accidental gulp of seawater is not harmful, relying on it for hydration leads to severe dehydration and puts immense strain on the body's vital organs. This biological fact is a crucial aspect of survival at sea, explaining why even when surrounded by water, a person can die of thirst.

While water covers over 70% of the Earth’s surface, only about 3% of it is freshwater. This vast ocean resource is unfortunately undrinkable for humans, a biological limitation that makes it essential to understand why can humans not drink salt water and how our bodies react to high salinity.

The world's oceans cover nearly two-thirds of the Earth's surface, yet this vast water supply is completely undrinkable for humans. The reason lies in a fundamental physiological conflict between our bodies and the ocean's high salinity.

Sodium is the sixth most abundant element in the Earth's crust, comprising about 2.6% of its mass. But where does sodium come from in a usable form, and how does it end up on our tables and in our food? This article explores its diverse origins, from ancient geological deposits to modern-day processing methods.
