Water is a critical source used all around the world to keep our way of life flowing. The use of water goes from regular house needs to creating energy in many ways. Around the world drinkable water starting to run low and the water stored is being contaminated by pollutants causing sickness and death. Countries are going through droughts which affects the water supply needed to maintain irrigation, and public supply. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment.
The public health intervention most widely used to prevent these diseases is the water fluoridation. It improves dental health by being incorporated into the tooth crystalline structure to form fluorapatite, the solubility of this is less than hydroxypatite, and also inhibits the demineralisation process or decay (M. Jason, 2010, p.656). The fluoride water disturbs the enzymatic process of caries which is causing bacteria and impedes odontopathic organism’s attachment to teethes; fluoride retards progression of caries through these processes (public health ethics, 2012, p. 2). Since the1960’s the drinking water has been fluoridated in many parts of Australia. Community water fluoridation is the fluoride adjustment in drinking water to a level that protects teeth by preventing decay (M. Mike, 2012, p. 1).
Although the economy has been developing, the quality of water in Tianjin is decreased year by year. Because of water pollution is getting worse; I have to install a household water purification system, to ensure the domestic water could be used safely. Meanwhile, water must be boiled because this process can ensure the water is harmless to the body. Water pollution not only increased my living costs but also caused a waste of energy.
A greywater recycling system can “reduce one’s water usage by about 50%” so in theory, one could potentially cut their water bills in half as well as reduce their water footprint ("What Are the Benefits of Water Conservation?”). These facts positively answer the question of whether or not greywater is cost-effective as it demonstrates that not only does this recycled water help to cut back on the amount of water used in a household, but it also saves users thousands of dollars, if not more, over the years. Greywater has been proven to be a very safe way of recycling water. There is not a single documented case of an illness in the developed world caused through greywater. Overall, the many benefits to using greywater outweigh the few negatives.
Does the city of grand rapids add fluoride to their water source? Why am I writing this paper? Well because it is an assignment and it will show the pros and cons of adding fluoride to the water. Cities started putting fluoride in the water in the late 1940’s. According to the website I read “ putting fluoride in the water decreased the number of cavities in children.” Fluoride is actually in water and foods already.
After the evaporation, the remaining part must be warmed up and condensed, so it can become freshwater (Nield, 2015, p.1). B. Advantages Using pervaporation will help us in many different ways. According to Danise (2015, p.1), the membrane can be built using cheap materials, which would be a great choice for developed countries. The technology can also clean water from high concentrated salt effectively (Nield, 2015, p.2).
Water fluoridation is to increase the level of the fluoride that occurs naturally in the water to reduce tooth decay and strengthen teeth. Fluorides are minerals found very commonly in the earth 's crust and in all water supplies. In the 1930s, American scientists discovered out much less tooth decay experienced by people living in areas with higher level of fluoride in the water, than people in area with lower fluoride level. Therefore from 1945, in America, once its effectiveness against tooth decay become obvious, water fluoridation community spread out rapidly (Australian Dental Association, Unknown Date) There are people who support the water fluoridation and people who oppose it. There are few number of advantages and disadvantage of water fluoridation that are commonly mentioned by people.
While we cannot control the rainfall, we are compelled to conserve and create water. There is a pond that I pass by every day when I drive to school. Through the last five years, it has greatly decreased in size and what was once green foliage surrounding it is now withered. This visual reminder reminds me to think carefully about how others and I use and waste water. While the Rainmaker is a great solution to the drought, there are steps that Californians can take to reduce their water consumption.
Compliance with rules has greatly improved through education (Indian companies target children to push green messages). Priest Mishra got support from India’s central government for a cleanup scheme (Ridge). Hindus, and others participating in the festival of Ganesh Chaturthi are complying with governmental efforts to use mud clay, papier mache, and natural paints when making their Ganesh idols (Gaur). Working together to purify this world-renowned river is a step in the right direction. However, it will take time to bring the pollution from Hindus to a halt and reverse the damage done (The Ganges River).
Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world. Most of the waste produced on land is either intentionally or unconsciously discharged into the oceans. Marine pollution and aquatic debris can utterly destroy the oceans causing extinction of the marine creatures. Innovative techniques should be implemented in the law to prevent the marine environment from any further damage. In order to improve the marine environment, the government and the Environment Public Authority of Kuwait should take immediate actions that can influence the society and help in minimizing aquatic debris and pollution.
