The Environment and Human Health - Coursework Example This can lower the concentration of oxygen to a level that is immediately dangerous for human health; (2) Frostbite. Solid carbon dioxide is always below -78 oC at regular atmospheric pressure, regardless of the air temperature. Handling this material for more than a second or two without proper protection can cause serious blisters, and other unwanted effects. Carbon dioxide gas released from a steel cylinder, such as a fire extinguisher, causes similar effects; and (3) Kidney damage or coma. This is caused by a disturbance in chemical equilibrium of the carbonate buffer. When carbon dioxide concentrations increase or decrease, causing the equilibrium to be disturbed, a life threatening situation may occur† (Lenntech, 2009, par. 29). b. Environmental Impact of Tire Discard The Tire Conversion Technologies (2008) indicated that the environmental impact of discarded tires range from â€Å"the aesthetic (ugly piles of tires stockpiled on a parcel of land) to the hazardous (poten tial for fire and toxic chemicals from smoke) to public health concerns (carelessly discarded tires are an excellent breeding ground for mosquitoes)† (par. 1). ...

Also, many of the buildings for the Olympics are being built with green features† (Howard, 2008, par. 4). The report confirms the acknowledgement of the China government and the Olympic promoters for the need to control high air pollution in Beijing and therefore resorted to drastic and immediate methods to curb pollution, hopefully, not only in the short term, but in the long run. 2. a. International and Intranational Water Conflicts A report authored by Shamir, a contribution from UNESCO’s International Hydrological Programme to the World Water Assessment Programme contained relevant information that provides examples of international and intranational water conflicts.
