Sustainability is the capacity to endure through renewal, maintenance, and sustenance, or nourishment, in contrast to durability, the capacity to endure through unchanging resistance to change. For humans in social systems or ecosystems, sustainability is the long-term maintenance of responsibility, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use. In ecology, sustainability describes how biological systems remain diverse, robust, and productive over time, a necessary precondition for the well-being of humans and other organisms. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. Robust, diverse, productive ecosystems and environments provide vital resources and processes (known as "ecosystem services"). There are two major ways of managing human impact on ecosystem services. One approach is environmental management; this approach is based largely on information gained from educated professionals in earth science, environmental science, and conservation biology. Another approach is management of consumption of resources, which is based largely on information gained from educated professionals in economics.

A scene from Oscar Wilde's 1895 play An Ideal Husband, originally published in a 1901 collected edition of Wilde's works. The comedy, which opened January 3, 1896, at the Haymarket Theatre in London, revolves around blackmail and political corruption, and touches on the themes of public and private honour. It has been adapted into television, radio/audio, and three films. The published version differs slightly from the performed play, for Wilde added many passages and cut others. Prominent additions included written stage directions and character descriptions. Wilde was a leader in the effort to make plays accessible to the reading public.

"Jack the Ripper" is the best known pseudonym given to an unidentified serial killer active in the largely impoverished areas in and around the Whitechapel district of London in 1888. The name originated in a letter by someone claiming to be the murderer that was disseminated in the media. Attacks ascribed to the Ripper typically involved women prostitutes from the slums whose throats were cut prior to abdominal mutilations. Rumours that the murders were connected intensified in September and October 1888, and extremely disturbing letters from a writer or writers purporting to be the murderer were received by media outlets and Scotland Yard. Mainly because of the extraordinarily brutal character of the murders, and because of media treatment of the events, the public came increasingly to believe in a single serial killer, Jack the Ripper. Extensive newspaper coverage bestowed widespread and enduring international notoriety on the Ripper. An investigation into a series of brutal killings in Whitechapel up to 1891 was unable to connect all the killings conclusively to the murders of 1888, but the legend of Jack the Ripper solidified. As the murders were never solved, the legends surrounding them became a combination of genuine historical research, folklore, and pseudohistory. The term "ripperology" was coined to describe the study and analysis of the Ripper cases. There are over one hundred theories about the Ripper's identity, and the murders have inspired multiple works of fiction. (Full article...)
