Introduction

´╗┐Introduction What is the ?Water Crisis? exactly? This term refers to the global problem of lack of access to clean water to the people of this earth. While the world's population tripled in the 20th century, the use of renewable water resources has grown six-fold. Within the next fifty years, the world population will increase by another 40 to 50 %. This population growth coupled with industrialization and urbanization will result in an increasing demand for water and will have serious consequences on the environment. This image shows the scarcity in most parts of the world. This scarcity affects people in many ways. Countless number of people die every day because of lack water, water-borne diseases and lack of water to water their crops. Facts about the Water Crisis: 1. 884 million people lack access to safe water supplies; approximately one in eight people. 2. 3.575 million people die each year from water-related disease. 3. Every 20 seconds, a child dies from a water-related disease. 4. Over 50 percent of all water projects fail and less than five percent of projects are visited, and far less than one percent have any long-term monitoring. 5. More than 80% of sewage in developing countries is discharged and untreated, polluting rivers, lakes and coastal areas. Why is water an inseparable part of life? The human body is 75% water and our blood is 90% water. ...read more.

Organic water pollutants refer to substances like plant residue, manure or sewage. When bacteria are in the water, it decomposes organic material which in turn decreases the oxygen level in the water. When the oxygen level is decreased, it kills organisms which in turn create a cycle where there are more decomposers in the water and less oxygen. This cycle is called eutrophication. Various Factors Which Lead to Water Crisis According to me, the main factor which leads to a water crisis is population overgrowth. Since there are more people, the demand for water will increase and it will become scarce. Another effect of population is that it will lead to more pollution as more factories will be opened and they will be dumping waste chemicals in bodies of water. Another effect is when trees are cut down to make space for houses and agriculture. When the trees are cut down, the soil can be eroded and contaminate rivers and other bodies of water. Misusage of water is another contributing factor. The reason why people waste water is because they are not educated on why water is so important and how scarce it is. They don?t know how to save water. Some people do not know how valuable water can be to the 2 billion people who don?t have access to clean water. ...read more.

Conclusion

Another way to purify water is through filtration but this is not fool-proof because there is no perfect filter which can prevent even the tiniest of residue from getting past it. If science could discover a fool-proof perfect filter, it would benefit a lot of people. Factors Environmental When science discovers new techniques of recycling waste chemicals that come out of the factories, there would be less toxic chemicals dumped into rivers and lakes around the world. This would benefit the environment because we are saving an ecosystem and marine creatures from dying because of being poisoned. Since all the ecosystems are interconnected, if even one ecosystem is disrupted, so will all the others and this is why it is important to prevent water pollution. Social Lots of people would be benefited if science discovers cheap ways of providing clean water to rural areas and to people who don?t have access to clean water. It is estimated that about 1 billion people don?t have access to clean water. All of these people could benefit if they had access to clean water and there wouldn?t be so many deaths caused by water-borne diseases. If they had access, it would prevent women and school children from walking kilometers under the sun to collect contaminated water. It would also allow the children to go to school instead of skipping school hours to find water. ...read more.
