ABSTRACT
Saline water makes up 97% of the total water present in the world, and only a small part refers to fresh water in the form of snow and ice, groundwater and surface water. Seawater can be a good source of water for drinking and industry and can provide minerals that are essential for health. Seawater contains many different ions (sodium, chlorides, magnesium, sulfates, calcium, bicarbonates, etc.), gases, organic matter and trace matter. Seawater has a far higher proportion of dissolved ions than fresh water. Oceans and seas are very important for the global climate because, among other things, they absorb a significant part of the carbon dioxide emissions that come from the process of burning fossil fuels. Marine ecosystems hide numerous plant and animal species that have adapted to life in that habitat for millions of years. The positive effect of saline water on the physical and mental health of people has been known for centuries. The use of saline water can improve the cholesterol profile, affect the cardiovascular system, prevent atherogenesis and affect skin changes. Marine water pollution is a matter of concern to public health authorities about the risks to human health associated with such use. Polluted waters cause a large number of different diseases, especially causing acute microbial diarrhea, which is a major public health problem in developing countries. Marine ecosystems, in addition to being a major source of food for humans and animals, in the future can occupy a significant place in the production of energy from renewable sources (tidal energy, wave energy and conversion of ocean heat energy).
