Golf

Golf is a sport in which a player, using many types of clubs including woods, irons, and putters, hits a ball into each hole on a golf course in the lowest possible number of strokes. Golf is one of the few ball games that do not use a standardized playing area; rather, the game is played on golf "courses", each one of which has a unique design and typically consists of either 9 or 18 holes. Golf is defined in the Rules of Golf as "playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules"

The first game of golf for which records survive was played at Bruntsfield Links, in Edinburgh, Scotland, in A.D. 1456, recorded in the archives of the Edinburgh Burgess Golfing Society, now The Royal Burgess Golfing Society. The modern game of golf spread from Scotland to England and has now become a worldwide game, with golf courses in the majority of affluent countries.
Golf competition is generally played as stroke play, in which the individual with the lowest number of strokes is declared the winner, or as match play with the winner determined by whichever individual or team posts the lower score on the most individual holes during a complete round.
Golf as a spectator sport has become increasingly popular, with several different levels of professional and amateur tours in many regions of the world. Players such as Arnold Palmer, Tiger Woods, Jack Nicklaus, Lorena Ochoa and Annika Sörenstam have become well-recognized sports figures across the world. Sponsorship has also become a huge part of the game and players often earn more from their sponsorship contracts than they do from the game itself.

Golf is played in an area of land designated a golf course. A course consists of a series of holes, each with a teeing area, fairway, rough and other hazards, and the green with the pin (flagstick) and cup. Different levels of grass are varied to increase difficulty or to allow for putting in the case of the green. A typical golf course consists of eighteen holes, but many smaller courses may only have nine. Early Scottish golf courses, and similarly designed courses, are mostly laid out on linksland, soil covered sand dunes directly inland from beaches. This gave rise to the common description of a seaside course as a golf links. The turn of the 20th century, with its widespread use of heavy earth-moving equipment, saw a movement toward golf course design with an emphasis on reshaping the land to create hazards, and add strategic interest. Modern golf course design has seen a return to its roots. Architects appreciate once again how to maximize the subtleties in the existing land while tempering how much dirt they move.

Environmental concerns over the use of land for golf courses have grown over the past fifty years. Specific issues include the amount of water and chemical pesticides and fertilizers used for maintenance, as well as the destruction of wetlands and other environmentally important areas during construction. The UN estimates that golf courses use about 2.5 billion gallons/9.5 billion liters of water daily, enough to provide drinking water for 4.7 billion people. In response, there has been research into more environmentally sound practices and turf grasses.
