When editors or teachers ask you to write in “APA style,” they do not mean writing style. They are referring to the editorial style that many of the social and behavioral sciences have adopted to present written material in the field.
Editorial style consists of rules or guidelines that a publisher observes to ensure clear and consistent presentation of written material. Editorial style concerns uniform use of such elements as
The American Psychological Association has established a style that it uses in all of the books and journals that it publishes. Many others working in the social and behavioral sciences have adopted this style as their standard as well.

Peace and survival of life on Earth as we know it are threatened by human activities that lack a commitment to humanitarian values. Destruction of nature and natural resources results from ignorance, greed, and a lack of respect for the Earth's living things... . It is not difficult to forgive destruction in the past, which resulted from ignorance. Today, however, we have access to more information, and it is essential that we re-examine ethically what we have inherited, what we are responsible for, and what we will pass on to coming generations. Clearly this is a pivotal generation... . Our marvels of science and technology are matched if not outweighed by many current tragedies, including human starvation in some parts of the world, and extinction of other life forms... . We have the capability and responsibility. We must act before it is too late. Tenzin Gyatso the fourteenth Dalai Lama.
