Fresh water makes up only about one percent of all the water on Earth. However, fresh water is essential for human life and other living organisms. The majority of Earth’s freshwater is stored in ice and snow in polar regions, with the rest being locked in other non-permanent forms, like groundwater or freshwater lakes. The world’s supply of freshwater is shrinking fast, due to pollution, overuse, and climate change. Freshwater ecosystems are also under threat from deforestation and urbanization. Understanding how much freshwater there is on Earth might help us protect our sources better. Let’s take a look at what percentage of Earth’s water is fresh and why it matters so much to us.
What Percentage Of Earth’s Water is Freshwater?
The most recent estimates from the United Nations put the world’s total water resources at about 1.4 trillion cubic kilometers. Of this, just 2.5% is freshwater, and 69% of that is locked up in glaciers and snow cover. So that leaves us with about 315,000 cubic kilometers of freshwater, of which only 3% is easily accessible (not accounting for pollution or other factors). That comes out to around 9,500 cubic kilometers of available freshwater per year.
How Much Water Is There On Earth?
1. The Earth is about 96.4% water, with the remaining 3.6% being mostly helium, neon, argon, and xenon. Water on Earth is divided into two main categories: freshwater and saltwater. Freshwater makes up about 97% of all water on Earth, while the remaining 3% is saltwater.
2. The amount of fresh water on Earth varies depending on your location. This means that the amount of freshwater in different parts of the world can vary considerably. For example, Egypt has a lot of fresh water because it has a lot of desert areas to store it in. On the other hand, Alaska has little or no freshwater because it has very few lakes or rivers to store it in. Freshwater makes up about 97% of all water on Earth.
3. Freshwater is essential for life on Earth. It’s necessary for drinking, bathing, and other activities that require a lot of water. The human body is made up of about 60% water, so we need to drink to stay alive.
4. The world’s supply of freshwater is shrinking fast, due to pollution and climate change. The world’s glaciers are melting faster than ever before, especially in places like Greenland and Antarctica, which are both experiencing record-breaking melting rates as they warm up due to climate change. Glaciers contain a lot of ice that can also be used to store freshwater in the future. However, if they melt too much or all at once, they could cause major flooding problems by releasing all that stored water into the ocean at once.
How Much Freshwater Is There?
1. Freshwater is made up of about 97% of the water on Earth.
2. Freshwater is found in oceans, lakes, rivers, and other bodies of water.
3. Freshwater lakes and reservoirs are important sources of drinking water for billions of people around the world.
4. The amount of freshwater on Earth has declined by about 1% per year since 1900 due to human activity. This trend is expected to continue with some negative effects on humans in the near future.
What Percentage Of Earth’s Water Is Freshwater?
1. Freshwater Is Essential To Life On Earth.
Fresh water is an essential part of the water cycle. The water cycle consists of evaporation, condensation, precipitation, and runoff. This process takes place in a series of six steps: evaporation, condensation, precipitation, runoff, storage, and discharge. Some freshwater is available only to live organisms and may not be present in large quantities. For example, freshwater can only exist in liquid form in ice or snow. However, this does not mean that fresh water cannot be found on Earth – it just has to be “hidden” somewhere else.
2. Freshwater Is Vital For Human Survival On Earth!
Freshwater makes up about 96% of the planet’s surface area at an average depth of 1 meter or 3 feet below sea level (see figure 2). Freshwater covers more than 70% of the Earth’s surface (see figure 4). The total amount of fresh water on Earth is estimated to be around 1,370,000 cubic kilometers.
3. Freshwater Is Essential To The Survival Of Life On Earth!
Freshwater is essential for the survival of life on Earth. For example, freshwater contains essential elements that are necessary for humans to survive (see figure 3). Without water, humans would not be able to survive. The human body needs water to survive, and it also needs water to absorb nutrients and grow. The human body uses more than 60% of its total mass in the form of water (see figure 5). Water is also needed for respiration and digestion by living organisms.
4. Freshwater Is Vital For Crops And Livestock Production!
Freshwater is vital for crops and livestock production. Crop production depends on adequate amounts of fresh water for irrigation purposes (see figure 6). For example, two-thirds of the world’s food supply comes from farming – most of which depends on rainfall or irrigation from freshwater to live for more than a few hours.
Why Is Knowing The Amount Of Freshwater Important?
1. Freshwater Is Essential For Human Life
Fresh water is essential for human life. It supplies drinking water, food, and industrial uses, such as electricity generation and the production of chemicals. There are more than 3 billion people who depend on freshwater for their livelihoods.
2. Freshwater Is Vital For Plants And Animals
It’s not just humans that need fresh water; plants and animals do too. A wide range of plants and animals use the water in rivers, lakes, seas and other bodies of freshwater to grow. Some of the most important freshwater species include fish, shellfish, several types of birds (including bald eagles), large animals like whales and seals (which can have a lifespan of 50-100 years), and many other species that live in or near freshwater bodies…we’re not even counting the microscopic creatures that live in these same bodies of water! The livelihoods of all these animals are also dependent on freshwater sources…from their food to their habitat, the freshwater supply is vital.
3. Freshwater Is Important For Food And Agriculture
Fresh water is essential for food production because it’s used to grow crops and raise livestock. In fact, without fresh water, there would be no food. As water becomes more scarce – due to overuse or pollution – the quality of freshwater available to us decreases. This means that we can’t produce as much food as we do today…making it harder to feed ourselves and our families in the future! The amount of freshwater that we use today depends on how much land we have available and how many crops are being grown. There are a number of ways that humans can use less water in the future…such as efficient irrigation techniques, which help increase crop yields by up to 50 percent!
4. Freshwater Is Important For Nature’s Balance
Freshwater also helps maintain nature’s balance by regulating salinity levels in oceans e no food, as nearly all plants need water to grow. The majority of the world’s crops are grown in the river basins of the Nile, Tigris-Euphrates, and Indus-Ganga rivers. The United Nations Food and Agriculture Organization (FAO) estimates that without fresh water, there would be no food to eat on Earth…that’s over a billion people!

Fresh water makes up only about one percent of all the water on Earth. However, fresh water is essential for human life and other living organisms. The majority of Earth’s freshwater is stored in ice and snow in polar regions, with the rest being locked in other non-permanent forms, like groundwater or freshwater lakes.
