The American society has been facing many challenges including the social and political conflicts that pose a big question on the sustainability of the common good. Common good has been a term that originated from the writings of Aristotle, Plato and Cicero, almost two thousand years ago. According to John Rawls common good is stated as: "certain general conditions that are equally to everyone's advantage".
Sir pollution has been increased to a devastating limit and posing a potential threat to the sustainability of all the nations across the globe. World Health Organization WHO has been doing efforts to maintain their Databases with the updated level of air pollution in all major countries (91 countries & 1100 cities), when found London to exhibit air pollution levels going up almost double since four years in March 2013 (Nick Evershed, Newcastle Herald).
Common or public good constitutes the broad spectrum of three main systems including:
Talking about the environment part, shrimp farming though has been a lucrative business contributing to the economic development in Vietnam. As with a boost in economic development shrimp farming has been a major threat concerning environmental pollution. In the past, many researches have been focused on the harmful and toxic effluents from Vietnamese shrimp farms and their direct impact on polluting surrounding waters. In addition to this the farmed shrimp’s health has been adversely affected due to this activity. The natural aquatic resources in the country have been a point of concern as there is very little knowledge regarding the adverse impacts of farming effluents. Many of the current studies are directed to highlight the water pollution and its consequences related to the shrimp farms on natural farms. May 2005 to April 2006 was the period selected for conducting a fieldwork was conducted in Can Gio, Ho Chi Minh City and Vietnam. The field work involved the collection of samples from water and shrimps directed at three different areas right out if the mainstream that included: -Area 1 (A1 - improved-extensive-farms) -Area 2 (A2 - intensive and semi-intensive farms) -Area 3 (A3 - semi-intensive and rice-shrimp systems). The above three areas were assessed against some of the viral parameters of water that decide the quality of water and fish biodiversity. These include the dissolved oxygen content as (DO), unionized ammonia (NH3-N), nitrite, chemical oxygen demand function (COD) and biochemical oxygen demand function (BOD5). As expected, the three different areas thus studied, exhibited statistically variant information with respect to the quality of water parameters. Findings of the study are as under: -The two latter areas A2 and A3 gave clear insight to traces of water pollution and supporting the study - The amount of Dissolved oxygen at A2 and A3 did not match the Vietnam standard and wre found to be lower. -the amount of nitrite, unionized ammonia, COD and BOD5, and COD in A2 and A3 wre reported to be higher than the allowed Vietnamese limits There was a vivid difference in the number of fish species found to exist in A2 and A3 as they fall remarkably below the other area A1 pointing to water pollution. This study is conducted to help and guide the shrimp farmers and the legal regulating bodies of environmental awareness among the local shrimp farmers and promoting sustainable farming systems to ensure environmental protection. The aim of this paper is to stress on the benefits imparted to all people due to access to healthy environment, clean air and benefits of unpolluted water and other social welfare aims for the betterment of public. There are social or societal institutions that work for the provision of benefits to common or public good. These institutions may include the legal systems, governments, hospitals, charities and foundations, business corporations and universities etc. According to Hiller (189-202) societal or social
