- Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare. Only 3% of the world’s water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use. As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year.

Introduction Surface waters make up the majority of the water used for public supply and irrigation. It plays less of a role in mining and livestock industries. Oceans, which are the largest source of surface water, comprise approximately 97 percent of the Earth's surface water. However, since the oceans have high salinity, the water is not useful as drinking water.

- Seventy percent of all the fresh water is used for irrigation. 1  agriculture uses the largest amount of freshwater (70%). 2  40 percent of the world grain harvest is produced on irrigated land, t herefore, a water shortage will become a food shortage. 3  Countries are importing grain as a way to import water.resh water is a finite resource. The amount of fresh water supply provided by the hydrological cycle does not increase. Water everywhere on the planet is an integral part of the global hydrologic cycle. Precipitation originates as evaporation from land and the oceans.

What percent of the earths water is available for human use?? Shockingly, only about 0.3%, which is not much. We get our drinking water from lakes, rivers, and resevoirs. Though earth is called the blue planet because of the 71% water on our planet, most of it is in oceans, ice caps, not usabe for drinking. As far as human use, I don't know if you mean drinking or other uses. Check the web site below.

Are we using up more than what is available? Only 2.5% of the world’s total water volume is fresh water. Of that 2.5%, 70% is frozen (2). The depletion of our water resources is more serious that the current oil depletion. There are substitutes for oil but nothing can replace our drinking water. 70% of the available fresh water that remains in used in agriculture, 20% in industry and only 10% is being used for human consumption.

Total Percent Of Fresh Water Remaining On The Surface Of The Earth Is Shockingly Small Only 0.000067 of the total water on earth is available on the surface as non-saline fresh water in our rivers, lakes, and streams. That’s just 1/150th of one percent of the total water on the planet! 0.0067 percent. That’s how precious our fresh water is.

Why Only One Percent of the Worldâs Water Is Drinkable NATURAL WATER Only 3% of the earth’s water is fresh, non-saline water. Of that non-saline water, 31% is accessible as fresh water. For every gallon of fresh surface water, there are 30 gallons that lie underground. The primary source of water for municipalities is ground water. Water is held in underground reservoirs known as aquifers.

Introduction But, the Earth cleans and replenishes the water supply through the hydrologic cycle. The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere. Still, much of the 0.3 percent that is useable is unattainable.

What percentage of the Earth's water is drinkable? This ice is fresh water and could be melted; however, it is too far away from where people live to be usable. Less than 1% of all the water on earth is fresh water that we can actually use. We use this small amount of water for drinking, transportation, heating and cooling, industry, and many other purposes.

Water resources Water resources. Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water. Only 2.5% of water on the Earth is fresh water, and over two thirds of this is frozen in glaciers and polar ice caps. Water demand already exceeds supply in many parts of the world, and many more areas are expected to experience this imbalance in the near future.

- People tend to think that the amount of water on the planet is unlimited, yet the amount of water on the Earth will actually stay the same. Of the water on Earth, 97.3% is oceans, inland seas, and salt lakes; the rest is fresh water (icecaps/glaciers, groundwater, freshwater lakes, atmosphere, rivers). The amount of available fresh water to humans and wildlife depends largely on how water quality is maintained.

How much water is there? How much water is there? Water covers nearly three-fourths of the Earth's surface and is mostly found in the oceans and seas. That sounds like a lot of water, right? Well, it is, but we can't drink much of it. Since more than 97% of the water on earth is in the form of salt water, only a tiny amount of water is usable as fresh, drinking water. Human beings cannot drink salt water. We need fresh water to survive. So, just exactly how much fresh water is there? Two percent (2%) of the water on Earth is in the form of frozen fresh water, but it is not usable by human beings. Only about 1% of the total water on Earth is in the form of fresh water that is found in lakes, streams, rivers, soil and underground reservoirs or aquifers.

- Why Is Water So Important ? by Alick Bartholomew. Water is the essential component of all life. It comprises 70% of the Earth's surface, 75% of. the human body, 90% of blood and sap. 97% of Earth's water is in the oceans, 2% is frozen in icecaps, 1% is fresh, but much of this is inaccessible, deep in the Earth. From what is. left, we use 98% for industrial purposes and agriculture, only 2% for the nutrition and health. of every living organism.

How Much of the Earthâs Water Is Drinkable? It is interesting and quite shocking to note that less than 1% of the water on earth is drinkable. Freshwater. This may come as a surprise for many because water makes up seventy-percent of the Earth’s surface. However, despite the fact that three-fourths of the Earth is made up of water, only 2.5% of this is freshwater, while the rest is in the form of sea water, and is therefore not suitable for drinking. Furthermore, of the 2.5% freshwater supply we have, the majority or 66.67% of this is in the form of ice caps or glaciers, which means that most of this is not available for human consumption.
