Basic Necessities Required For Sustaining Life

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.

Around the world our water supply is depleting. Our water is becoming contaminated making it harmful for both mammals and aquatic life. Today over one billion people go without adequate water supply and every fifteen seconds a child dies of waterborne illness. Sources of water that once supplied water to millions can no longer meet the supply and demand of the water need. Scientist predict that the amount of useful water will keep depleting greatly in the years to come. In the next couple of pages it will talk about both the geological and human reasons as to why are water supply is depleting.

According to “Implications of Growth”, in many parts of the world natural water sources are already pushed to and past their limits. The human population greatly relies on water, therefore, it is essential and necessary to the future population growth in the entire world.

Water, like food, is a necessity for human life that is used for many purposes such as agricultural, industrial, and domestic systems. While water is a common element around the world not all of it is clean and able to be consumed or used by humans. With only a percentage of the world’s water being clean and the use of water increasing, the availability of water around the world has become a common issue in the developing and even the developed world. This may be a smaller problem in areas close to clean water sources compared to areas far from a clean water source but, the availability of water is not strictly based on location, it also depends on the specific political and social needs and issues of the area as well. These all become issues that must be accounted for when deciphering whether water is a basic human right or a commodity and what action must be taken to aid the developing water systems in community’s that lack them.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

Many people know that water is essential for human-being and it is not only valuable for health and life, but water is also important for industry and agriculture. Furthermore, use of water has a spiritual, cultural and recreational dimension. However, water resources are not infinite. Wide and inefficient use of water resources can lead to irreversible consequences, such as water shortage. This essay will firstly discuss the problem of water shortage on examples of developed and developing countries and include the diversification of the same issue in the different parts of the world. It will also identify causes and effects of this environmental problem on society and other spheres of life. Moreover, in this essay I am going to propose

Water is essential for life as we know it on earth. It is used by plants

Cloudy pond water – heterogeneous mixture, this is because it is cloudy, solute is dirt particles - in the water there is clay and humus.

Water is considered as an essential for human existence. We all can survive without food for some day but no one can live without water at least two days. Human body consists of 70% percent of water and our globe is covered by 69.9% percent of water. But unfortunately the useable fresh water is just 2.5% out of it. Water is a social good, water is an economic good, water has ecological value and water has religious, moral and cultural value.

It is clear that global water needs rose significantly between 1900 and 2000, and that agriculture accounted for the largest proportion of water used. We can also see that water consumption was considerably higher in Brazil than in the Congo.

Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes

Whether we realize it or not, water is surrounding us in different forms everywhere. Water actually makes up about 70% of Earth. Water is overall known as a good solvent that dissolves minerals it comes in contact with. As water moves through earth, it dissolves minerals and holds them in solution. The amount of metal cations, such as Calcium (Ca^2+) and Magnesium (Mg^2+) in water became known as water “hardness”. Water hardness can be detected by white residue and crystal like rocks when heated. Understanding water hardness is important to us because it has proven to create problems both in our households and in industry (1). These problems lead to expenses for homeowners and industry owners, they will end up spending money on expensive cleaning chemicals and machinery cleaners. In our household we water hardness pop up as soap scum in our dishes and in our laundry. Hard water also produces scale which, in industry and again in households can narrow pipes, block tubes, cause problems in brewing facilities, and can produce problems in farmland. The greater the presence of Calcium and Magnesium in water defines its hardness. For example a water sample with a large concentration of these two cations, along with smaller amounts of other polyvalent cations, is considered to be hard. (1, 2) And a sample with a smaller concentration of the cations is considered soft. Below is a table of the determination of water hardness scale.

Water is the lifeblood of every living creature on earth. Approximately 70 percent of the earth's surface is covered with water. Thought the wonders of nature, water can take on many different forms, form the water we drink, to the ice we use to chill a glass of lemonade, to the water vapor used to steam clean equipment equipment. It is easy to understand the significance water plays in our lives, but it may be much more difficult ot understand the water that exists below the earth's surface, called groundwater.

Interactions between groundwater and surface water are complex. Consequently, groundwater pollution, sometimes referred to as groundwater contamination, is not as easily classified as surface water pollution.[7] By its very nature, groundwater aquifers are susceptible to contamination from sources that may not directly affect surface water bodies, and the distinction of point vs. non-point source may be irrelevant. A spill or ongoing releases of chemical or radionuclide contaminants into soil (located away from a surface water body) may not create point source or non-point source pollution, but can contaminate the aquifer below, defined as a toxin plume. The movement of the plume, a plume front, can be part of a Hydrological transport model or Groundwater model. Analysis of groundwater contamination may focus on the soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants.

It is an essential resource for sustaining life as well as central to agriculture and rural development, and is intrinsically linked to global challenges of food insecurity and poverty, climate change adaptation and mitigation, as well as degradation and depletion of natural resources that affect the livelihoods of millions of people across the world. According to the World Bank, (2010) report, water is a scarce resource with multiple interwoven uses that range from drinking water, energy, irrigation, manufacturing things, transport of people and goods among others. The report further states that, more than one-sixth of the Worlds’ population does not have access to safe drinking water, with 80% living in rural areas thus access to water cannot not be guaranteed globally.
