In the early twentieth century disposability, and the notion of using something once and then throwing it away grew to become a sign of wealth and cleanliness. Consumers were encouraged to use disposable products for their efficiency and to avoid contamination. The ideas of purification and convenience encouraged the development of ethical justifications for the use of disposable items.
Packaging plays an important role; it protects our food from contamination, dirt, and germs.
Logically we think that using a paper bag is a better alternative than non-biodegradable plastics. However, for every lorry needed to transport plastic bags to where they are needed it would take 7 lorries to deliver the same number of paper bags.
We must also consider the effects on scarce water supplies to maintain healthy plant production. If we were to replace plastic bags with paper in this country, it would require ‘a hundred and seventy million acres of extra forest land for paper production, an area the size of the United Kingdom […] and would also raise annual energy consumption by more than 225% each year’.
There are situations where the use of single use plastics are appropriate. In a medical setting where we want to avoid contamination, particularly when the skin is punctured. By using Smart syringes where the needle retracts as it is used ‘will hopefully help eliminate the 1.7 million new hepatitis B cases, the 300,000 hepatitis C cases and the 35,000 HIV cases every year’
