Today, people are facing many serious problems about the environment. Some of the urgent issues are biodiversity loss, pollution and water scarcity. However, the problem, which needs to be more considered is the water scarcity. It means the existing water sources are depleting due to the increased needs in human activity. This is an important issue because water is a major factor of life. It is very necessary to grow crops for food and many other needs in life. This essay will examine about the main causes of water scarcity. In addition, it also looks at two possible solutions: technological development and water conservation. The main reasons for water scarcity are human activities. There has been an increase in world’s population led to the demand is higher. Glennon (2005, p.5) points out that the development of population is the cause of an increase in the needs of water supply. Therefore, the water resources are more and more disappearing. There has been the depletion in safe water supplies in some areas of America (Glennon, 2005, p.3). Furthermore, human is using too much water to grow crops for food as well as agriculture farming. The United Nations (2008, p.3) points out that the water resources are depleting again because the amount of water that uses for irrigation is fourfold in comparison with the past. A solution for depleting water source is improved technology to get more water from the environment. A part of the method is desalination because most surface of the planet covered by 70 per cent ocean water. This means some countries can use technologies to remove salt from the seawater for drinkable water and it is a possible method to find other fresh water sources from nature (Glennon, 2005, p.12). What is more, drip irrigation is also a way to solve the issues water by techniques. In agriculture, farmers usually choose this technique to
