Vegetarianism encompasses the practice of following plant-based diets (fruits, vegetables, etc.), with or without the inclusion of dairy products or eggs, and with the exclusion of meat (red meat, poultry, and seafood). Abstention from by-products of animal slaughter, such as animal-derived rennet and gelatin, may also be practiced.

Vegetarianism can be adopted for different reasons. Many object to eating meat out of respect for sentient life. Such ethical motivations have been codified under various religious beliefs, along with the concept of animal rights. Other motivations for vegetarianism include health, political, environmental, cultural, aesthetic or economic. There are varieties of the diet as well: an ovo-vegetarian diet includes eggs but not dairy products, a lacto-vegetarian diet includes dairy products but not eggs, and an ovo-lacto vegetarian diet includes both eggs and dairy products. A vegan diet excludes all animal products, including eggs, dairy, and honey.

Various packaged or processed foods, including cake, cookies, chocolate and marshmallows, often contain unfamiliar animal ingredients, and may be a special concern for vegetarians due to the likelihood of such additions. Often, products are scrutinized by vegetarians for animal-derived ingredients prior to purchase or consumption. Vegetarians vary in their feelings regarding these ingredients, however. For example, while some vegetarians may be unaware of animal-derived rennet's role in the usual production of cheese and may therefore unknowingly consume the product, other vegetarians may not be bothered by its consumption. The results of a 2009 International survey suggest the standard definition of vegetarianism is different in different nations. Vegetarians in some nations consume more animal products than those in others.

The Cure are an English alternative rock band formed in Crawley, West Sussex in 1976. The band has experienced several line-up changes, with frontman, vocalist, guitarist and principal songwriter Robert Smith being the only constant member. The Cure first began releasing music in the late 1970s with its debut album Three Imaginary Boys (1979); this, along with several early singles, placed the band as part of the post-punk and New Wave movements that had sprung up in the wake of the punk rock revolution in the United Kingdom. During the early 1980s, the band's increasingly dark and tormented music helped form the gothic rock genre.

After the release of Pornography (1982), the band's future was uncertain and Smith was keen to move past the gloomy reputation his band had acquired. With the 1982 single "Let's Go to Bed" Smith began to place a pop sensibility into the band's music (as well as a unique stage look). The Cure's popularity increased as the decade wore on, especially in the United States where the songs "Just Like Heaven", "Lovesong" and "Friday I'm in Love" entered the Billboard Hot 100 chart. By the start of the 1990s, The Cure were one of the most popular alternative rock bands in the world. The band is estimated to have sold 27 million albums as of 2004. The Cure have released thirteen studio albums, 10 EPs and over thirty singles during the course of their career. Since 2010, they have been working on a fourteenth studio album.

Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.

Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.

Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.
