All animals need water and air to live, and the pollutants that exist in them often do not leave the tissues of the consuming animal. Compounds like mercury and lead are absorbed by animals further down on the food chain and are collected in higher and higher levels as each animal is consumed on its way up the food chain (ADEQ, 2009). With humans on the top of this food chain, it is easy to see how all of the aggregate mercury contamination in Arizona's fish and cattle populations would end up pooling in the human population. Soil contamination affects everyone for generations to come, since homes and businesses will likely be built on mine tailings and other polluted areas of land in the future. These soil contaminants have to be removed from the soil manually, which is very expensive and time-consuming. There is much evidence that Arizona has started to reverse the effects of a century of mining, farming, ranching, and coal-powered energy production. But the...
The infrastructure and technology is in place for the state to begin to see some real positive results, and the permitting and waste clean up that has begun to occur has certainly put a positive dent in this very negative situation. Public transportation and other community-based projects will likely become part of Arizona's future, and help the pollution problem in the state as well (UPI, 2009).
This initiative roughly costs $4.4 million when fully implemented (CDC, 2010). The city council should make sure that there are policies that promote walking and cycling to work by providing bicycle storage at public transportation stations, bus stops, and city car-share points. Authorities should also ensure that there are well-lighted cross-walks and signal timing. The cyclists and the pedestrians need to use the road and the intersections freely with
Nitrate, Aluminum, And Lead in Drinking Water Three mayor harmful chemicals that affect water's natural condition are nitrate, aluminum, and lead. In recent years, public fears over the contamination of drinking water by these and other contaminants have grown. Certainly, the public is right to be concerned about the possible health effects of aluminum, nitrate, and lead. Aluminum has long been linked with an increased risk of Alzheimer's disease, bone diseases
The solution that Hardin proposes is that of a coercive method; as always he gives a lucid example to support the point that he proposes. Hardin reminds the reader that society mutually agreed to make it illegal to rob banks, rather than appeal to the sense of responsibility to those who wish to rob banks as a means of deterring them. Bank robbers (real and potential) know that very immediate
Disposable batteries have transformed the way that we live and the types of activities that we do. The purpose of this discussion is to provide the reader with a natural history of disposable batteries from the time the raw materials are extracted from the earth to the time they are recycled or in a land fill. We will seek to explain the environmental impact that batteries have along the path
Indoor Air Quality This report discusses viable options for reducing indoor pollutants in order to improve indoor air quality. This work focuses on three major concerns in regard to indoor air quality: poor ventilation, indoor smoking, and other indoor pollutants. The media bombards us daily with information regarding external pollution such as the emissions from automobiles, water contaminants, basic garbage and of course the smoke stacks of industry. But most
