Water consumed this year  (million of liters) The data on water consumption in the world is provided by the United Nations (UN, UNESCO, and FAO, see list of publications below). Worldwide, agriculture accounts for 70% of all water consumption, compared to 20% for industry and 10% for domestic use. In industrialized nations, however, industries consume more than half of the water available for human use.

Why is so little of Earth's water available for human use? Lets look at this: First of all, only 2.5% of the Earth's water is fresh water. Of course, making salt water drinkable is possible, but inefficient due to the Earth's population. (Its pricy!) Now, 68.7% of freshwater on Earth is in the poles, frozen.

Water distribution on Earth Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 70% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot.

What percentage of the Earth's water is drinkable? 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.

Drinking water Water covers some 70% of the Earth's surface. 1  Approximately 97.2% of it is saline, just 2.8% fresh. Potable water is available in almost all populated areas of the Earth, although it may be expensive and the supply may not always be sustainable. Sources where water may be obtained include:

How Do We Use Water and Why Conserve? All of the water that we use comes from local lakes, rivers, streams or underground aquifers, depending on your city and state. Household Uses. Common household uses consume a lot of water. It may take between 30 and 40 gallons for one bath while the average toilet uses about 5 gallons of water per flush.

Uses of Water Most of this water use was fresh water, about 341,000 MGD, or about 85 percent, while 60,800 MGD was saline water. The majority of fresh-water withdrawals, about 264,000 MGD, or about 77 percent, came from surface-water sources, while about 76,400 MGD came from groundwater. The source of saline water is surface 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.

WATER CONSUMPTION AROUND THE WORLD THE USA. In the United States the population growth is one of the highest in industrialized countries and the average American uses over 420 litres per day. This is one of the highest in the world, and with diminishing supplies this has forced the government to increase prices and change its approach to water supply.

Atom 1 Nearly 98% of the Earth's water is in the oceans. Freshwater makes up less than 3% of water on earth, and over two-thirds of this is tied up in polar ice caps and glaciers. Freshwater lakes and rivers make up only 0.009% of water on Earth and groundwater makes up 0.28%.  Water is essential for all life forms.

- That’s hard to imagine if you just think about drinking water, flushing the toilet and taking a shower. But most of it comes from 'hidden' water usage; the water needed to grow the food we eat and make the products we use. The total global requirement for water is over four trillion litres a year.

- Water is a finite resource: there are some 1 400 million cubic kilometres on earth and circulating through the hydrological cycle. Nearly all of this is salt water and most of the rest is frozen or under ground. Only one-hundredth of 1 percent of the world's water is readily available for human use. This would be enough to meet humanity's needs-if it were evenly distributed.

Environmental Science: Earth's Water Even though the planet is 71 percent water, the largest percentage of Earth's water is saltwater in the oceans and cannot be used for drinking. The table describes the main locations of water on Earth. Notice that about 98 percent of Earth's water is saltwater. The remaining 2 percent is freshwater, but the majority of that percentage is found in the polar ice caps and glaciers, which is not readily available to us.

- We only have the water that we have now. Ninety-seven percent of all the water on the earth is salt water which is not suitable for drinking. Only three percent of all the water is fresh water, and only one percent is available for drinking water. The other two percent is locked in ice caps and glaciers.

Water quantity FAQ Frequently Asked Questions Front and back of the earth. The blue area represents water. As oceans are very wide and there are multiple to be found on earth, oceans store most of the earth's water. This is apparently 97% of the total amount of water on earth, 2% of which is frozen. Of all the water on earth, which is 97,14% of the total amount of surface water, only 2,59% is freshwater. Of this 2,59% another percentage is trapped in ice caps and glaciers, which is about 2%.
