Sea water is not tasty. It is salty, and often bitter, due to the high concentration of dissolved minerals, primarily sodium chloride (table salt).
Here's why:
- High Salt Content: Sea water contains about 3.5% salt by weight. This is significantly higher than the salt concentration we find palatable in our food and drinks.
- Other Minerals: Besides salt, sea water contains other minerals like magnesium, potassium, and calcium, which contribute to its bitter taste.
- Evolutionary Adaptation: Our taste buds are designed to detect and enjoy the taste of fresh water, which is essential for survival. The salty, bitter taste of sea water signals our bodies that it's not suitable for drinking.
While sea water is not tasty, it's crucial for life on Earth. It supports a vast ecosystem of marine life and plays a vital role in regulating the global climate.
