Processing of findings The Importance of Water: Water is life and ultimately it is essential to life. For millions of years life on earth has been dependant on water for survival. 70% of the earth’s surface is covered with water but of this, approximately 97% is salt water, with the remaining 3% being fresh water (Water wise, 2016) Of this 3%, less than 1% is available for life on earth to both drink and use in our households, whilst the rest is in the form of ice at the poles and thus one can see the need for water on our Earth as only 1% can be used for life on Earth. The amount of water on earth is similar to energy it is constant kit cannot decrease or increase or be created, however, water can be destroyed through pollution and not caring for it properly, but it is unevenly distributed across the earth. South Africa receives an annual rainfall of 497 mm whereas the rest of the earth receives 860 mm.
According to a study conducted by the US geological survey, “about 71% of the Earth is covered by water” (Perlman). Based on that number, people think there is plenty of water for us to use and never ask how much of that 71% is usable for our daily activities. According to Jay Withgott, who is an environmental scientist at Yale University, “only 2.5% out of 71% of water is available for our daily life” (WithGott & Brennan, p.255). This means that we have over used the water resources than it’s generated. Therefore, this paper will describe how water is used in our homes, ways to save water, and the benefits of saving water.
Introduction For this research task I have chosen compare various methods of water purification in a household as researching the health and environmental factors. I will look at the following sources of water: Oasis purified water, bottled water and the municipal tap water (Municipal- muzunduzi). I will be looking at the effect of each source on the natural environment. My reason for doing this as my research task is that I personally think that purified water is generally healthier for you due to all the chemicals that is found in the municipal water. In my house we only drink water bought from Oasis so I thought this would be a very interesting project to research due to its closeness to the home.
The water-crisis claims more lives through disease than any war through guns. More than eight hundred million people lack access to safe drinking water. This is more than the combined populations of the United States, Brazil, Japan, Germany, France and Italy. Many organizations work to improve water conditions in developing countries. From 1990 to 2006 the
"When the well is dry, we learn the worth of water", Benjamin Franklin. Water; the most fundamental building block for a thriving ecosystem. Providing ample amounts of freshwater has been a major issue in human history, tracing back to the ancient civilizations. Despite being around for hundreds of centuries, even today 1 out of 6 people do not have access to water, and more than double that lack basic sanitation. The distribution of fresh water has always been a problem, and now as the world faces a growth by up to 1 billion by 2030, the issue is strained to continue to supply not only safe drinking and bathing water, but also enough to support farming and industrial practices.
When they eventually get home, the little water they collected is contaminated. This causes diseases the need for medical assistance to rise to enormous amounts. If untreated, one person – especially babies – die every 19 seconds! Each day, almost one billion people live like this… and we just carry on wasting
DUET Karachi Date: 18-10-2016 Purpose and Introduction: Water is the most essential and most important thing in the earth. Every human being and every living organism need water. 80% of human body’s made by water. Water is crucial element of our food and materials. 75% of earth’s surface is covered with water, and only 3% is clean water and only 1% of the water is available for human consumption.
Everyone requires freshwater in order to live, as a result about 1.1 million people in this world lack access to freshwater. In India alone, only 18% of the population has access to freshwater. 38 million people in India are affected with waterborne diseases each year. Almost 75% of them are children. This is just in India, which is a developing country right now.
It is reported that 80% of all illness in developing countries is related to water and sanitation (Pritchard, Mkandawire & O’neill). It is estimated that more than 3 million people die every year due to infectious diseases caused by drinking contaminated water. The majority of people affected are young people of age younger than 5 years (Viji, Priyanka, Manish & Pawn, 2013). Access to safe drinking water in Mutele village is complex. Many households in Mutele village lack access to piped water in their homes, and as a result of that people go to rivers, wells and springs to fetch water using containers (Viji, Priyanka, Manish & Pawn, 2013).
Agriculture is currently the largest user of water at the global level. The food production and supply chain accounts for about 30% of total global energy consumption. Rice and wheat are the staple food in South Asia. It is about 50% of dietary energy comes from these two crops. However, these crops need about 1000 tonnes of water to produce 1 tonne of grain (Brown, 2009).
