* Water is a natural resource of the utmost importance; nothing on earth can survive without it. Aside from drinking, water is used for agriculture, cooking, bathing, cleaning, industrial purposes and sanitation. When the demand for water exceeds its supply for an extended period of time, scientists refer to the situation as water stress. This serious issue leads to lower quantity and quality of freshwater resources. While most causes are human-related, others are uncontrollable. Population Growth * An increase in people means more water usage for bathing, washing dishes, cooking and other activities. World population tripled in the 1900s, resulting in six times the usage of water resources, reports World Water Council. With the …show more content…
Drought, caused by excessive sunlight and little to no rainfall for long periods, is a major cause of water stress on plants and agriculture, resulting in a reduction of crop yields. Little rainfall means less moisture within the soil, making it difficult for plants to exert the energy needed to get water. Wind can also contribute by causing plants and soil to dry out more quickly. Saline * Soil and water with high levels of salt also cause water stress. Saline adds weight to water, which puts incredible stress upon plants to draw the water in. Many crops are destroyed by salt water. Although water is abundant throughout the world, most is contained within expansive oceans. Only 2.5 percent is not saltwater and can be used by humans. Of this 2.5 percent, only one-third is liquid freshwater. Glaciers and permanently snow-covered regions contain the rest. Pollution * Rampant pollution of water can render it unusable. Humans litter and industrial plants dump waste into freshwater rivers, lakes and streams. This waste typically contains toxic chemicals that make the water dangerously unhealthy. If the problem is not resolved, an estimated 18,000 square kilometers of freshwater around the world could be destroyed by 2050, according to an article from The Age in Australia.

Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.
Water scarcity is an environmental problem that reaches around the globe. This lack of water is called the World Water Crisis. In the U.S, people are privileged enough to be able to use clean water for many things. However, the U.S is effected by water scarcity as well as countries who are underdeveloped and aren 't as privileged as we are. Only 2.5 percent of Earth 's water is fresh water, of which industrial uses account for 22 percent of available fresh water, domestic use requires only 8 percent, and the rest-over two-thirds of our demand-is used for agriculture. Water is said to be a right for all living things, however, many underdeveloped countries in the world, such as Ghana or Rajasthan, are victims of corporations who come
Climate change is arguably the greatest threat to humanity and the worst of it’s effects are fast approaching. It is the basis of a myriad of problems, one of which is water scarcity. As the world population grows and the climate warms, demand for fresh water has surged-- with water scarcity affecting more than 40 percent of the global population (United Nations, 2010). Conversely, the world’s fresh water supplies are dropping. Water is indispensable to biotic existence. While it aided in humankind's creation, it can also aid in its downfall. Bearing these elements in mind, one can consider the implications of this water crisis: What are the threats to its quality? Who will it affect? Is water a right or a commodity? What are the social, economic, and political variables and how do they connect? And ultimately, how can we fix this? Throughout my research I seek the answers to these critical questions.
Some areas of the world are already considered water stressed. In areas that are water stressed, the amount of sustainable water is running low. The people in these regions are in need of new and clean water to start being present. According to Roberts, “By 2050 more than half the world’s
The polluted water supply that results can become harmful to humans. Aquatic life quickly suffers the effects of watershed pollution.
Water pollution is when, “one or more substances have built up in the water to such an extent that they cause problems for animals and people” (Woodford). Water pollution is also bad for humans and animal’s health. Sewage, chemicals, radioactive waste, oil pollution, and plastic, are some causes for water pollution (Explain That Stuff). When water from rain runs off roofs and roads into rivers it carries away trash, toxic chemicals, dirt, and harmful organisms (NRDC Water). Some solutions to these are to throw things into the correct bin, use water wisely, and not throw chemicals, oil, paints, and medicine down the sink, drain, or toilet. Also plant lots of trees and have cities develop a sewage treatment plant to minimize pollution (eSchool Today). It’s important to protect our
The water crisis in the world is increasing, and it will continue to increase if something is not done. Water makes up approximately seventy-one percent of Earth’s surface. This does not include the water underground. Everyday water is being taken more than it is being put in, and people have a large role in this. Climate change, the number of people in the world, and water wasted is among the uppermost causes of the water crisis. It is simple, if you do not have water, you will eventually die. The water crisis is a health crisis for everyone globally.
Water issues are big concern for every living thing on the planet. As the worlds population grows and the demand of products increase, industries are growing too. This demand on the worlds recourses especially water is becoming an issue. Around two percent of the worlds water is drinkable with much being locked up in glaciers. Moving water to places in need is a common practice, but this dose not make more drinking water. While salt water is easily accessible we can not consume it. The water must be processed with the salt being removed.
We have the world filled with people, towns, cities, and tons more stuff, but what really covers two-thirds of the Earth surface is water. When the world adds more populations in our world than our water sources increases. In our world, we have so many rivers and oceans, but the one river that is fresh and produces water the most is the Nile River.
Water is found everywhere on earth : from ice-covered lakes to tropical rains, yje surface of our planet is covered with almost three quarters of water. However, water is still one of the most precious resource for humanity : only 2.5% of water is pure. Water is therefore a renewable but no unlimited natural resource which is at the center of many debates : considered as the most sever threat in the world, water shortage crisis is spreading in the news. This essay will discuss the following : first, we will see how water is linked to everything; ten we will see that water crisis has a lot of repercussions on developing countries and their growth. Finally we will discuss
In the present world, water has become a highly contested resource. It is no secret that we are consuming much more water than humanity originally intended. Consumerism is such a prevalent factor in today 's society, which is why multi-billion dollar companies thrive at economic development. As a global population we are shackled by society, forced to conform to the materialistic viewpoints that were adapted from prior generations. The trend will inevitably continue if we do not begin to challenge our society, as well as economy. Water is one of the only resources that humanity is
Through the day an average United States citizen uses anywhere from eighty to one hundred gallons of water. This number doesn't even include the vast amounts that are trickling away through broken and leaky pipes, dripping faucets, and even people unnecessarily leaving the water on. Even though people use vast amounts of water, much of this water can be saved by doing simple daily tasks slightly differently. One example of this is the time it takes to shower. Simply by reducing one's shower time to five minutes would help save water. Another simple task to do is to wash dishes with the sink filled with water instead of constantly flowing water down the drain. Every wasted drop of water can and would be used for other things if given the opportunity. An increasing population simply means that more water is needed. More for agriculture, more for toilets, and more to keep people from dying of
water scarcity is the biggest threat to our food security. agriculture uses about 70 percent of all our freshwater from rivers every single year from around the world. river water is used to irrigate farms and feed billions of people around the world. the level of threat to the ongoing supply of fresh water available depends on the place. river systems and the water that the farmers capture store and distribute are the most threatened natural environments on earth. an increasing demand for water is by far the most common threat to food security around the world. with so much water being used it is easy to run out of the water what makes the crops die of dehydration.
The global supply of freshwater resources depends on different regions. The picture on the right shows that 97% of the global water supplies is found in the oceans, which contain saline. A small amount of salty water is the remaining 3% is fresh water. Icecaps and glaciers are about 69% of the total freshwater supply. In addition, fresh water is found underneath the Earth's surface as groundwater, which is estimated to be 30% of the total freshwater supply and in surface water storages such as lakes, streams, and swamps. Small amounts of freshwater are also deposited in the soil, the atmosphere and in organic
Water has always been -- and will always remain -- the basis of life on Earth. Scientists have yet to find a single living and breathing creature that is able to survive without the supply of such a powerful substance. Humans can live for a month without food, yet we can only survive a week without water (Ali Gold Robets). The importance of water has not been as truly appreciated as it should be until now. With water reservoirs shrinking, the global water crisis will only continue to grow. Within the next decade, humanity will begin to see a shift where water will replace oil as our most valuable resource.
