The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
The World Bank gives the total gross domestic product (GDP) in 1997 as $31.435, which would about equal the biosystem value. [4] Criticisms were addressed in a later publication, which gave an estimate of $125 trillion/yr for ecosystem services in 2011, which would make them twice as valuable as the GDP, with a yearly loss of 4.3–20.2 ...
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.

Prices for irrigation water that is being provided by a public agency are also typically determined administratively, usually using a flat rate, since metering is not common in agriculture in most countries of the world. The following pricing systems exist for irrigation: [6] Area-based tariffs, sometimes differentiated by type of crop grown
That’s much higher than the European Food Safety Authority recommendations that men drink 10.5 cups or 2.5 liters of water per day and women drink 8.3 cups or 2 liters per day.
This water — believed to be seven miles to 12 miles (11.5 kilometers to 20 kilometers) down in the Martian crust — most likely would have seeped from the surface billions of yea
Using the Federal Reserve’s $2.3 trillion M0 currency figure and a current world population of 8.17 billion, per Worldometer, there’s about $282 per person in the world, on average. Using the ...
