Question
The total amount of municipal solid waste (MSW) generated in the United States has increased from 80 million metric tons (88 million U.S. tons) in 1960 to 232 million metric tons (255 million U.S. tons) in 2007.
(a) Describe reasons for this increase and explain how the United States became the leader of the “throw-away society.”
(b) Explain why reducing is more favorable than reusing, which in turn is more favorable than recycling.
(c) Describe the process of composting and compare a home composting system with that of a large-scale municipal facility.
Given the differences in health risks that exist between low- and high-income countries, consider the following issues.
(a) What strategies might you use to reduce the health risks of low-income countries?
(b) What strategies might you use to reduce the health risks of high-income countries?
(C) Suppose a low-income country discovers oil and is projected to become a high-income country within a decade. what changes in the country’s healthcare system might you suggest?
Explanation / Answer
a)the reasons are that manufacturing of solid products increased exponentially becaause of which solid waste also increased exponentially and also the three R reduce ,reuse ,recycle are not followed properly
the other reasons are also : population increased, as the u.s. began to industrialize people were able to buy household items that could be used then thrown away. Some objects even contained materials that were hard to recycle. the u.s. became the leader of the "throw away society" by inventing household items that could be used and then thrown away; plastic forks and spoon, paper plates and cups, disposable diapers.
b) Reduce is more favorable than reuse because it reduces the amount of a substance used which will then reduce the amount that is discarded. Reuse is more favorable than recycling because it allows for the substance to kept in the cycle for a longer period of time and energy is not needed to do this whereas in recycling, energy is used.
c) Composting creates organic matter that has decomposed under controlled conditions to produce an organic-rich material. Home composting system can be as simple as food and yard waste in the corner of the yard while and large scale compost systems consists of piled up organic material that is turned to expose to the mixture of air and water which will speed the process up
2) differences in health risks between low and high income countries
a) Provide means for good childhood nutrition and prenatal care.
Provide sources of clean water.
Provide clean-burning fuels for cooking and heating.
Provide high-quality medical care
b) Provide information about good nutrition and wellness.
Reduce air pollution.
Encourage exercise and discourage use of tobacco products.
Emphasize the importance of a well-managed, safe workplace
c) There should be more emphasis on wellness, good nutrition, and timely medical checkups
