Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, mammoths, ground sloths, thylacines, trilobites and golden toads. Through evolution, species arise through the process of speciation—where new varieties of organisms arise and thrive when they are able to find and exploit an ecological niche—and species become extinct when they are no longer able to survive in changing conditions or against superior competition. The relationship between animals and their ecological niches has been firmly established. A typical species becomes extinct within 10 million years of its first appearance, although some species, called living fossils, survive with little to no morphological change for hundreds of millions of years. Mass extinctions are relatively rare events; however, isolated extinctions are quite common. Only recently have extinctions been recorded and scientists have become alarmed at the current high rate of extinctions. Most species that become extinct are never scientifically documented. Some scientists estimate that up to half of presently existing plant and animal species may become extinct by 2100. A 2018 report indicated that the phylogenetic diversity of 300 mammalian species erased during the human era since the Late Pleistocene would require 5 to 7 million years to recover.According to the 2019 Global Assessment Report on Biodiversity and Ecosystem Services by IPBES, the biomass of wild mammals has fallen by 82%, natural ecosystems have lost about half their area and a million species are at risk of extinction—all largely as a result of human actions. Twenty-five percent of plant and animal species are threatened with extinction.In June 2019, one million species of plants and animals were at risk of extinction. At least 571 species have been lost since 1750, but likely many more. The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming.A dagger symbol (†) placed next to the name of a species or other taxon normally indicates its status as extinct.A crisis (plural: "crises"; adjectival form: "critical") is any event or period that will lead, or may lead, to an unstable and dangerous situation affecting an individual, group, or all of society. Crises are negative changes in the human or environmental affairs, especially when they occur abruptly, with little or no warning. More loosely, a crisis is a testing time or an emergency. Circumstance or circumstances may refer to:Surroundings are the area around a given physical or geographical point or place. The exact definition depends on the field. Surroundings can also be used in geography (when it is more precisely known as vicinity, or vicinage) and mathematics, as well as philosophy, with the literal or metaphorically extended definition. In thermodynamics, the term (and its synonym, environment) is used in a more restricted sense, meaning everything outside the thermodynamic system. Often, the simplifying assumptions are that energy and matter may move freely within the surroundings, and that the surroundings have a uniform composition. Carson may refer to:Glastonbury (, UK also ) is a town and civil parish in Somerset, England, situated at a dry point on the low-lying Somerset Levels, 23 miles (37 km) south of Bristol. The town, which is in the Mendip district, had a population of 8,932 in the 2011 census. Glastonbury is less than 1 mile (2 km) across the River Brue from Street, which is now larger than Glastonbury. Evidence from timber trackways such as the Sweet Track show that the town has been inhabited since Neolithic times. Glastonbury Lake Village was an Iron Age village, close to the old course of the River Brue and Sharpham Park approximately 2 miles (3 km) west of Glastonbury, that dates back to the Bronze Age. Centwine was the first Saxon patron of Glastonbury Abbey, which dominated the town for the next 700 years. One of the most important abbeys in England, it was the site of Edmund Ironside's coronation as King of England in 1016. Many of the oldest surviving buildings in the town, including the Tribunal, George Hotel and Pilgrims' Inn and the Somerset Rural Life Museum, which is based at the site of a 14th-century abbey manor barn, often referred to as a tithe barn, are associated with the abbey. The Church of St John the Baptist dates from the 15th century. The town became a centre for commerce, which led to the construction of the market cross, Glastonbury Canal and the Glastonbury and Street railway station, the largest station on the original Somerset and Dorset Joint Railway. The Brue Valley Living Landscape is a conservation project managed by the Somerset Wildlife Trust and nearby is the Ham Wall National Nature Reserve. Glastonbury has been described as having a New Age community, and possibly being where New Age beliefs originated at the turn of the twentieth century when a feminine landscape was created where Christianity had ‘first touched Britain’, which attracts people with New Age and Neopagan beliefs, and is notable for myths and legends often related to Glastonbury Tor, concerning Joseph of Arimathea, the Holy Grail and King Arthur. Joseph is said to have arrived in Glastonbury and stuck his staff into the ground, when it flowered miraculously into the Glastonbury Thorn. The presence of a landscape zodiac around the town has been suggested but no evidence has been discovered. The Glastonbury Festival, held in the nearby village of Pilton, takes its name from the town.
