The dangers of salt pollution of Freshwater if preventive measures are not taken
Increased water salinity could have very high economic costs due to loss of ecosystem services and direct costs related to water treatment for human consumption. Human activities such as agriculture and resource extraction (coal, minerals, gas, etc.) are increasing water salinity and this has adverse effects on human health and ecosystem functioning. scientists call for global solutions and preventive policies based on the scientific consensus, taking into account social, economic and environmental issues in order to protect aquatic ecosystems from increasing salinity and to ensure access of future generations to the goods and services these ecosystems provide.The researchers propose incentives for good practices and the use of technology that will reduce salt concentrations in freshwater. For example, they argue for new agricultural techniques with cultivation of crops that permit a rational use of water. They also recommend permits and controls for enterprises that discharge salt-rich effluents into rivers and lakes in order to control the concentration and timing depending on the dilution capacity of receiving waters, as it is being done in Australia.
About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Only 2.5–2.75% is fresh water, including 1.75–2%frozen in glaciers, ice and snow, 0.5–0.75% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers. We have so much water but most of it is ruined by salt. Water water everywhere but not a drop to drink.
