Water is the basis of all life on earth and in the last few centuries human activities have degraded our fresh water supply more than any time in history. The Earth needs it to keep its moderate temperatures, vegetation needs it for its cohesive nature, and as a solvent it’s part of almost every chemical reaction inside our bodies. Even our own cells are made of 70% to 95% water. The increasing pollutants we have introduce into our water supply inhibits the properties of water that are so vital to life. Almost all great civilizations in history have built their cities near clean fresh water sources. For example, Ancient Rome was built near the River Tiber, and they eventually ended up polluting the river so much that they had to build …show more content…
With an increase in population, the U.N. Food and Agriculture Organizations estimates that food production will need to increase by 70% by the year 2050, placing a greater strain in our water supply. Today 70% of fresh water consumption comes from agriculture (United Nations World Water Development Report (UNWWDR), 2008), up to 90% in developing countries (Fry, 2009). The problem with increased agriculture production is the inefficient irrigation techniques that are use, up to 15% to 35% of irrigation is unsustainable (Fry, 2009). Meaning that we are using more water than we have to. For instance, one of the most striking events that deals with water over extraction has been the shrinking of the former fourth largest lake in the world, the Aral Sea in Asia. Aral Sea has been so heavily extracted for water since the 1960’s that today only 10% of it remains and it is predicted to disappear altogether by 2020 (Macklin and Aladin, 2008). Although 70% of the surface of our planet is cover by water only 2.5% is fresh water. Most of this fresh water is inaccessible for human consumption with most of it being trap in glaciers or underground (Fry, 2005). Earth has been able to clean and replenish our fresh water supply that humans and animals have used for millions of years. The Earth uses a natural cycle that is called the hydrologic cycle of water that includes: changes in state, precipitation, condensation, the atmosphere, evaporation, infiltration, runoff and
Water is a necessity for the existence of human beings and approximately 71 % of the earth is water and it exists in many different forms. Water is constantly moving from one place to the other and from one state to the other and this process is known as the water cycle. As water evaporates, vapors rise and condense into clouds. The clouds move over the land, and precipitation falls in the form of rain, ice or snow. The water fills streams and rivers, and eventually flows back into the oceans where evaporation starts the process anew. Although water continuously changes states, from solid to liquid to gas, the amount of water on Earth remains constant. There is as much water now as there were hundreds of millions of years ago (Project, 1995).
The Earth is a huge planet this is covered by 70 percent water. Astonishingly from this 70 percent the human population can only use 1 percent of the world’s water the rest of it is salt water, frozen, or in some way unattainable (Santa Clara Valley Water District, 2016). Humans have found many different ways to obtain this 1 percent of fresh water they need, but the techniques vary depending on location. In San Jose, California we obtain our water from 3 major sources: groundwater, imported surface water, and local mountain surface water. These 3 sources contribute different amounts of water to the San Jose community. Imported surface water composes about 50 percent of our water supply, while ground water composes roughly 40 percent, and local mountain surface water composes approximately 10 percent (Santa Jose Water Company, 2016). However, these percentages can change due to factors such as weather and global warming.
Water is all around us. This substance is of high importance to every living thing which is on planet earth. As much as we consider water to be life and the most important substance, still we don’t seem to appreciate it very much, as it is being wasted in such great amounts. Everyone believes that water will always be around but not taking into account that the majority of the water on planet earth are not for human consumption. Human beings can only survive on consuming fresh water. The percentage of
The society cannot afford to ignore the fact that water resources are limited. According to IFPRI (International Food Policy Research Institute), by 2050, there will be 4.8 billion people who will be struggling with limited water resources. This is over half of the world’s population. As the world’s population grows, there will be a greater need for economic development and more food. Factories producing grain use water more than any other input. In fact, water accounts for almost half of all inputs in the manufacturing industry across the globe. By
“Water is the driving force of all nature” a famous quote from Leonardo da Vinci [1]. Unfortunately, supplies are now running low at an alarming rate. The world’s population continues to soar but this growth in numbers has not been matched by an increase in availability of fresh water. In the last 50 years, the human population has more than doubled [2]. This rapid
Since the beginning of time fresh water has been a necessity for life, but only in recent years has the resource started to trickle away. This has been caused by the population explosion of the past few decades and the industrialization of the world. It is very simple to understand that there is only a certain amount of fresh water on the planet and when the demand for it exceeds the supply, you are going to run out of the fresh water. With the population more than doubling in the past decade just means more thirsty people and the need for more food. With the world being industrialized, more and more factories and companies need water for cooling and powering their machines. This is causing unprecedented water consumption and the Earth cannot keep up.
Freshwater ecosystems such as rivers and lakes provide drinking water, food, energy, transportation and even joy. But a staggering amount of fresh water is wasted or spoiled every day. Experts warn that in the next 20 years, half of the world’s population could face water shortages. There are practical solutions to freshwater conservation. These solutions ensure we meet our current needs and conserve this precious resource for
The air we breathe is essential to keep us alive, the same also apply for the water. From every forms of life, the production of as little as a paper clip to as big as an airplane, everything needs water. Water covers 70 percent of the earth’s surface with 96.5 percent found in seas and ocean, known as saltwater or seawater. The rest 3.5 percent is known as freshwater which the primary source of water needed to support our life, found in groundwater and in glaciers and the ice caps of Antarctica and Greenland. Nonetheless, “of that small number, less than 1 percent is easily accessible for human use; most of the rest is locked up in polar ice caps or buried deep in underground aquifers that catch and hold groundwater” (Haugen and Musser
Human survival on earth relies on water as an everyday necessity, creating the urge to preserve water. The earth’s surface is covered by 71 percent water. Water is also found in rivers, lakes, glaciers, ground soil, and aquifers. Water is vital to every aspect of human life, directly and indirectly; therefore, it is imperative to conserve it to ensure that the cycle of life continues. Water supports vegetation resulting in the creation of
“There has been significant public attention paid to the issue of water scarcity, and for good reason. Although water is a renewable resource, it is also a finite one. Only 2.53 percent of earth’s water is fresh, and some two-thirds of that is locked up in glaciers and permanent snow cover. But despite the very real danger of future global water shortages, for the vast majority of the nearly one billion people without safe drinking water, today’s water crisis is not an issue of scarcity, but of access” (Water.org, 2015).
Water covers approximately seventy percent of the Earth surface, but less than one percent of that is available for human use. The world must share this small amount for agricultural, domestic, commercial industrial and environment needs. Across the globe, water consumption has tripled in the last fifty years. Managing the supply and availability of water is one of the most critical natural resource issues facing the United States and
One of the most important resource that every lifeform requires to strive is undoubtedly water. Water is the start to every lifeform and continues to be the reason why there’s so much life on Earth. We have continually used water for many years. It is a necessary resource that needs to be used by all living beings in order to survive. In the past fresh water was considered a valuable Today water is taken for granted and there are many people that that don’t care about preserving water as much as other do. This is becoming a major concern since the amount of natural fresh water is not very high compared to the amount of water that is unusable. Which makes even more important to take an effort to reduce the amount of pollution to water.
Water is one of the necessities of life for people all around the world. It seems like a basic need that is readily available, as 70% of the Earth’s surface is covered in water. However, many people lack a source of clean drinking water. Unfortunately, this number, as well as the number of people who die due to not having clean water, is rising. According to the Natural Resource Defense Council, “Less than two-tenths of 1 percent of the planet’s water is drinkable, and 90 percent of that goes to uses in buildings, including flushing toilets.” Therefore, only a minuscule fraction of the water of the water on Earth is available for drinking. In addition, the average American uses 2,220 gallons of water per day, a number out of proportion with the 844 million people who lack access to safe drinking water. While these statistics sound dire, there are ways to solve this problem. The problem isn’t that we don’t have enough water, but how we use the water we have. If we utilize water and the other resources we have access to in an effective way, we can supply the human race as well as other species with sufficient water to survive.
There are a few facts about water that compels great concern and these should be noted. The cosmos holds an average of 1.4 billion cubic kilometers of water and of this, the fresh water resources constitute on average 35 million cubic kilometers, say 2.5% of the entire volume. Shifting attention to the fresh water resources, 24 million km3 or say 70% is preserved by nature in the form of ice or permanent snow covers on mountain tops as well as the arctic region. The other almost 30% is stored underground in the form of ground water leaving only 0.3% fresh and usable water in the rivers and fresh water lakes, a paltry 200,000 km3 of fresh and usable water (UN Water, 2013).
We all have heard that 70 percent of the Earth’s surface is water-covered – most of it in the form of oceans. Though it may sound like a lot, the fact that most of them are not fresh water. According to Jay Kimball 's calculation, it shows that freshwater in the world is only 10.7 billion cubic kilometers. It means clean water represents 0.77 percent of total volume of water in the Earth. In addition, we also have 1.74 percent of clean water which can be seen in different places such as the ice, glaciers, and permanent snow, but these resources are almost untouchable. The Food and Agriculture Organization of the United Nations (FAO) projects that two-thirds of the planet will be water stressed by 2025 (Kimball). So are you ready for
