There are many ramifications of the development of modern conveniences for individuals and their families over the past 150 or more years. The many labor-saving devices have kept pace with growing houses and furnishings and allow for greater
leisure. There are also some negative effects, some of which are also as the result of advancements in
chemical technology in the food that we eat or products that we use. In these cases there are also conflicting opinions about the extent to which some of the products are harmful. Here are a few examples of positive and negative effects of modern conveniences.
Positive effects Health care Some of the major improvements over the past century has been in improved
health care. For example,
modern medicine has made leaps in preventing
infectious diseases in part due to improved
water and
sewage treatment. This is obvious in the marked rises in
life expectancy.
Technological advancement in underdeveloped countries Some of the most dramatic technological benefits are seen in underdeveloped countries. For instance, cabling for
landline telephone service is expensive and requires a lot of time to complete, especially in the most remote areas. Introduction of
cellphone service, on the other hand, is much cheaper and dramatically improves individual's ability to be economically productive, often in
microbusinesses. It is estimated that 80% of the world's population is now located within range of cellular towers, 1.5 billion cellular phones are in use in developing countries and, in India alone, five million customers sign up for cellular service each week. The
Four Asian Tigers—i.e.,
Hong Kong,
Singapore,
Taiwan, and
South Korea—are a few of the countries that have leveraged technology to become a presence in the global community. :Another example, led by
Nicholas Negroponte of
MIT's
Media Lab in rural Asia, Latin America and Africa, provides $100 laptop computers to underdeveloped countries.
Meat consumption Because of the enormous productivity growth in
intensive agriculture and
meat industry, meat has become a major part of the diet in most developed countries and is on the rise in developing countries.
Red meat consumption has been linked to
colon cancer; besides,
growth hormone and
antibiotics treatment of cattle and poultry has raised serious concerns about the adverse effects of those substances in industrially produced meat.
Processed food and food preparation :
Processed foods,
high-fructose corn syrup, and increased fat—the greater reliance on processed, packaged, microwaveable food has resulted in a rise in
Type 2 diabetes,
obesity, and other health concerns.
Margarine, once seen as a great alternative to butter, does not help with absorption of
nutrients and may contribute to
heart disease.
Other :
Styrofoam cups release
styrene as the food or drink is consumed.
Leaded fuel is another hazardous chemical. Although it has been outlawed in the United States, its use in developing countries impacts the health of local people and the global environment. ==See also==
