A forest, also referred to as a wood or the woods, is an area with a high density of trees. As with cities, depending on various cultural definitions, what is considered a forest may vary significantly in size and have different classifications according to how and what of the forest is composed.[vague] These plant communities cover approximately 9.4 percent of the Earth's surface (or 30 percent of total land area), though they once covered much more (about 50 percent of total land area), in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the biosphere. Although forests are classified primarily by trees, the concept of a forest ecosystem includes additional species (such as smaller plants, fungi, bacteria, and animals) as well as physical and chemical processes such as energy flow and nutrient cycling.
A typical forest is composed of the overstory (canopy or upper tree layer) and the understory. The understory is further subdivided into the shrub layer, herb layer, and also the moss layer and soil microbes. In some complex forests, there is also a well-defined lower tree layer. Forests are central to all human life because they provide a diverse range of resources: they store carbon, aid in regulating the planetary climate, purify water and mitigate natural hazards such as floods. Forests also contain roughly 90 percent of the world's terrestrial biodiversity.
A festival or gala is an event, usually and ordinarily staged by a local community, which centers on and celebrates some unique aspect of that community and the Festival.
Among many religions, a feast is a set of celebrations in honour of God or gods. A feast and a festival are historically interchangeable. However, the term "feast" has also entered common secular parlance as a synonym for any large or elaborate meal. When used as in the meaning of a festival, most often refers to a religious festival rather than a film or art festival.
In the Christian liturgical calendar there are two principal feasts, properly known as the Feast of the Nativity of our Lord (Christmas) and the Feast of the Resurrection, (Easter). In the Catholic, Eastern Orthodox, and Anglican liturgical calendars there are a great number of lesser feasts throughout the year commemorating saints, sacred events, doctrines, etc.
The word fest derives from the Middle English, from Middle French word festivus, from the Latin word festivus. Festival was first recorded as a noun in 1589. Before it had been used as an adjective from the fourteenth century, meaning to celebrate a church holiday. The etymology of feast is very similar to that of festival. The word "feste" comes from Middle English, from Middle French, from the Latin word festa. Feast first came into usage as a noun circa 1200, and feast was used as a verb circa 1300. A festival is a special occasion of feasting or celebration, that is usually religious. There can be many different types of festivals, like Halloween, Saturnellia, and Christmas.
