In this kind of essay, the aim is to explain the causes (reasons) or the effects (results) of an event or situation.
e.g. Causes of air pollution (multiple factors leading to air pollution).
e.g. Effects of watching too much TV (many effects of a situation).
Depending on the topic, there may be three patterns of organization:
1. Multiple causes–>effect
In this pattern, the organization is as follows:
thesis statement: Air pollution is caused by the following factors: exhaust gases from cars, uncontrolled factory releases, and burning of low-quality coal for heating.
I. exhaust gases from cars
A. government does not have enough control
B. citizens are not conscientious
II. uncontrolled factory gases
A. no regular checks on gases released
B. factories are inside the borders of residential areas
III. burning of low-quality coal for heating
A. no governmental control
B. other forms of energy too expensive
Each developmental paragraph is devoted to one of the causes of air pollution. Each cause is supported by two minor supports. While writing, these major and minor ideas should be adequately explained and exemplified as well.
2. Cause–>Multiple effects
In this pattern, the effects of a certain situation are explained in separate paragraphs, with the following organization:
thesis statement: Watching too much TV is one of the major sociological issues of this century, which has many effects on the physiology and psychology of people.
I. eating disorders
A. TV meals
II. communication problems
A. more violence
B. no interpersonal talk
Cohessive devices used in cause and effect essays:
To explain reasons and results, we use:
-As a result,
-As a consequence,
-One reason why …
-One of the most important reasons why …
-The main reasons why …
-There are other reasons, too, …
Do not forget that using transitions enables the piece of writing to be coherent; it is easier for the reader to follow our ideas when transitions are used to link them together. However, overuse of transitions causes a traffic jam and should be avoided. We should be using transitions sparingly (only when necessary).
Sample cause and effect essay:
EFFECTS OF WATCHING TOO MUCH TV
Discoveries and invention of devices are always welcome till we, humans, find a way to abuse its benefits and be adversely affected by it. This was the case when Wilhelm Roentgen discovered x-ray and within five years, the British Army was using a mobile x-ray unit to locate bullets and shrapnel in wounded soldiers in the Sudan. TV was also invented with positive thoughts in mind – there would be no national borders, education and communication would be worldwide, etc. However, we are now trying to overcome its physiological and psychological adverse effects on human beings.
One of the physiological effects of watching TV in excessive amounts is eye-strain. It is true that there are specifications for watching TV; TV should be 5 m. away from the eye, the room should be adequately lit, TV should be placed at the same height with our eyes, etc. However, these do not prevent our eyes from getting tired if we keep watching TV for a long time. Another effect is obesity, which is widely observed in people who like watching TV and eating snacks everyday (there is even a term “TV snacks” to refer to fast food that is suitable for eating in front of the TV). TV is such a powerful machine that people cannot get away from it – it is addictive.
Apart from the physiological effects, TV also causes psychological effects. One is a result of being exposed to violence. After seeing so many violent scenes on TV, people start considering violent actions normal and they lose their sensitivity to their environment. Partly connected to this effect, the interpersonal communication among people decreases. Being insensitive to the suffering of other people causes people to become alienated. Also, after coming home from work people seek to relax in front of the TV, and generally people prefer watching TV to talking to each other. This issue is very important since lack of interpersonal relationships mostly end with divorces.
Shortly, inventions are meant to be beneficial for human beings, if we know how to benefit from them. TV is one of such inventions that need to be used for the right purpose only – being educated and entertained for a reasonable (according to age) period of time. We may, then, be safe from or at least reduce the adverse physiological and psychological effects of watching too much TV.
