While population and demand on freshwater resources are increasing supply will always remain constant.

How much water is available for human use. Water is the fundamental ingredient for life on Earth. So if only 31 of the fresh water is available for drinking this means 31 of 25000775 which equates to less than 1. The average person will need 5 liters of water to drink daily to survive in a moderate climate with little activity.

There are a number of countries across South Asia Africa and Latin America which use more than 90 percent of water withdrawals for agriculture. You can find it in the atmosphere above us in the ocean rivers and lakes around us and in the rocks below us. Since surface water is easier to reach its become the most common way for humans to access clean water.

The daily four-to-six cup rule is for generally healthy people. Only 1 of the worlds fresh water is accessible for direct human uses. 79 percent for middle income and only 41 percent at high incomes.

Every ninety seconds a child dies of a water-related disease usually diarrhea from inadequate drinking water sanitation or hygienedeath and suffering that is preventable. Each American uses an average of 88 gallons of water a day at home. Only 100 gallons of that is household use per person as most is used for agriculture according to water expert Peter Gleick.

Geological Survey or USGS and the human body is about 60 percent water. The world has about 333 million cubic miles of water according to the US. 1 of the worlds fresh water 0007 of all water on earth is accessible for direct human uses.

The 2015 estimates put total withdrawals at the lowest level since before 1970 following the same overall trend of decreasing total withdrawals observed from 2005 to 2010. The average agricultural water use for low-income countries is 90 percent. We can all use at least 20 percent less water by installing water-efficient fixtures and appliances.

Here we see large variations geographically and by income level. Due to geography climate engineering regulation and competition for resources some. Of groundwater per day.

Agriculture alone can consume 75 to 90 of a regions available freshwater. So fresh clean water accounts for just 0003 of all water available globally. Of all of the water on Earth 97 is saltwater leaving a mere 3 as freshwater approximately 1 of.

Water use in the United States in 2015 was estimated to be about 322 billion gallons per day Bgald which was 9 percent less than in 2010. Of the fresh water available on earth only 31 is accessible for use. Most people need about four to six cups of water each day.

The Ten Facts One. Only this amount is regularly renewed by rain and snowfall and is therefore available on. Globally we consume around 4 trillion cubic meters of fresh water a year.

The rest is either salt water found in oceans fresh water frozen in the polar ice caps or too inaccessible for practical usage. 663 million or one in ten people in the world lack access to clean water. About 69 of the fresh water is in form of ice cap and glacier in places like the Antarctic and Greenland ice sheet further reducing the quantity of the available drinking water.

Globally we use about 321 billion gallons of surface water and about 77 billion gallons of groundwater per day. The Earth might seem like it has abundant water but in fact less than 1 percent is available for human use. This is the water found in lakes rivers reservoirs and those underground sources that are.

An average American uses 100 to 175 gallons of water per day. How much water should you drink a day. Water found in lakes rivers reservoirs and those underground sources that are shallow enough to be tapped at an affordable cost.
