International Union for Conservation of Nature
–
The International Union for Conservation of Nature is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in gathering and analysis, research, field projects, advocacy, lobbying. IUCNs mission is to influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of resources is equitable. Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to equality, poverty alleviation. Unlike other international NGOs, IUCN does not itself aim to mobilize the public in support of nature conservation and it tries to influence the actions of governments, business and other stakeholders by providing information and advice, and through lobbying and partnerships. The organization is best known to the public for compiling and publishing the IUCN Red List. IUCN has a membership of over 1200 governmental and non-governmental organizations, some 11,000 scientists and experts participate in the work of IUCN commissions on a voluntary basis. It employs approximately 1000 full-time staff in more than 60 countries and its headquarters are in Gland, Switzerland. IUCN has observer and consultative status at the United Nations, and plays a role in the implementation of several conventions on nature conservation. It was involved in establishing the World Wide Fund for Nature, in the past, IUCN has been criticized for placing the interests of nature over those of indigenous peoples. In recent years, its relations with the business sector have caused controversy. It was previously called the International Union for Protection of Nature, establishment In 1947, the Swiss League for the Protection of Nature organised an international conference on the protection of nature in Brunnen. It is considered to be the first government-organized non-governmental organization, the initiative to set up the new organisation came from UNESCO and especially from its first Director General, the British biologist Julian Huxley. At the time of its founding IUPN was the international organisation focusing on the entire spectrum of nature conservation Early years. Its secretariat was located in Brussels and its first work program focused on saving species and habitats, increasing and applying knowledge, advancing education, promoting international agreements and promoting conservation. Providing a solid base for conservation action was the heart of all activities. IUPN and UNESCO were closely associated and they jointly organized the 1949 Conference on Protection of Nature. In preparation for this conference a list of endangered species was drawn up for the first time

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

President of the United States
–
The President of the United States is the head of state and head of government of the United States. The president directs the executive branch of the government and is the commander-in-chief of the United States Armed Forces. The president is considered to be one of the worlds most powerful political figures, the role includes being the commander-in-chief of the worlds most expensive military with the second largest nuclear arsenal and leading the nation with the largest economy by nominal GDP. The office of President holds significant hard and soft power both in the United States and abroad, Constitution vests the executive power of the United States in the president. The president is empowered to grant federal pardons and reprieves. The president is responsible for dictating the legislative agenda of the party to which the president is a member. The president also directs the foreign and domestic policy of the United States, since the office of President was established in 1789, its power has grown substantially, as has the power of the federal government as a whole. However, nine vice presidents have assumed the presidency without having elected to the office. The Twenty-second Amendment prohibits anyone from being elected president for a third term, in all,44 individuals have served 45 presidencies spanning 57 full four-year terms. On January 20,2017, Donald Trump was sworn in as the 45th, in 1776, the Thirteen Colonies, acting through the Second Continental Congress, declared political independence from Great Britain during the American Revolution. The new states, though independent of each other as nation states, desiring to avoid anything that remotely resembled a monarchy, Congress negotiated the Articles of Confederation to establish a weak alliance between the states. Out from under any monarchy, the states assigned some formerly royal prerogatives to Congress, only after all the states agreed to a resolution settling competing western land claims did the Articles take effect on March 1,1781, when Maryland became the final state to ratify them. In 1783, the Treaty of Paris secured independence for each of the former colonies, with peace at hand, the states each turned toward their own internal affairs. Prospects for the convention appeared bleak until James Madison and Edmund Randolph succeeded in securing George Washingtons attendance to Philadelphia as a delegate for Virginia. It was through the negotiations at Philadelphia that the presidency framed in the U. S. The first power the Constitution confers upon the president is the veto, the Presentment Clause requires any bill passed by Congress to be presented to the president before it can become law. Once the legislation has been presented, the president has three options, Sign the legislation, the bill becomes law. Veto the legislation and return it to Congress, expressing any objections, in this instance, the president neither signs nor vetoes the legislation

Theodore Roosevelt
–
Theodore Roosevelt Jr. was an American statesman, author, explorer, soldier, naturalist, and reformer who served as the 26th president of the United States from 1901 to 1909. As a leader of the Republican Party during this time, he became a force for the Progressive Era in the United States in the early 20th century. Born a sickly child with debilitating asthma, Roosevelt successfully overcame his health problems by embracing a strenuous lifestyle and he integrated his exuberant personality, vast range of interests, and world-famous achievements into a cowboy persona defined by robust masculinity. Home-schooled, he began a lifelong naturalist avocation before attending Harvard College and his first of many books, The Naval War of 1812, established his reputation as both a learned historian and as a popular writer. Upon entering politics, he became the leader of the faction of Republicans in New Yorks state legislature. Returning a war hero, he was elected governor of New York in 1898, the state party leadership distrusted him, so they took the lead in moving him to the prestigious but powerless role of vice presidential candidate as McKinleys running mate in the election of 1900. Roosevelt campaigned vigorously across the country, helping McKinleys re-election in a victory based on a platform of peace, prosperity. Following the assassination of President McKinley in September 1901, Roosevelt succeeded to the office at age 42, making conservation a top priority, he established a myriad of new national parks, forests, and monuments intended to preserve the nations natural resources. In foreign policy, he focused on Central America, where he began construction of the Panama Canal and he greatly expanded the United States Navy and sent the Great White Fleet on a world tour to project the United States naval power around the globe. His successful efforts to end the Russo-Japanese War won him the 1906 Nobel Peace Prize, elected in 1904 to a full term, Roosevelt continued to promote progressive policies, but many of his efforts and much of his legislative agenda were eventually blocked in Congress. Roosevelt successfully groomed his close friend, William Howard Taft, to succeed him in the presidency, after leaving office, Roosevelt went on safari in Africa and toured Europe. Returning to the United States, he became frustrated with Tafts approach, failing to win the Republican presidential nomination in 1912, Roosevelt founded his own party, the Progressive, so-called Bull Moose Party, and called for wide-ranging progressive reforms. The split among Republicans enabled the Democrats to win both the White House and a majority in the Congress in 1912, Republicans aligned with Taft nationally would control the Republican Party for decades. Frustrated at home, Roosevelt led an expedition to the Amazon basin. During World War I, he opposed President Woodrow Wilson for keeping the country out of the war, and offered his military services, although planning to run again for president in 1920, Roosevelt suffered deteriorating health and died in early 1919. Roosevelt has consistently ranked by scholars as one of the greatest American presidents. Historians admire Roosevelt for rooting out corruption in his administration, but are critical of his 1909 libel lawsuits against the World and his face was carved into Mount Rushmore, alongside those of George Washington, Thomas Jefferson, and Abraham Lincoln. Theodore Roosevelt Jr. was born on October 27,1858, at East 20th Street in New York City and he was the second of four children born to socialite Martha Stewart Mittie Bulloch and glass businessman and philanthropist Theodore Roosevelt Sr

Pelican Island National Wildlife Refuge
–
Pelican Island National Wildlife Refuge is a United States National Wildlife Refuge located just off the western coast of Orchid Island in the Indian River Lagoon east of Sebastian, Florida. The refuge consists of a 3-acre island that includes an additional 2.5 acres of surrounding water and is located off the east coast of Florida of the Indian River Lagoon. Established by an order of President Theodore Roosevelt on March 14,1903. It was created to protect egrets and other birds from extinction through plume hunting, Pelican Island’s bird populations were threatened because of increased American settlement around the area in the mid-19th century. Many of the birds were killed for their feathers, used in the fashion industry. Plumes from the birds were used to adorn ladies hats of the day, Paul Kroegel, a German immigrant, moved to Florida in 1881 and lived on the west bank of Indian River Lagoon. He was fascinated with the pelicans on the island, being able to see the island from his home, Paul would watch the pelicans and other water birds. He eventually took an interest in the island and its protection, however, there was not any state or federal law to help him so he took control of the situation himself. Kroegel sailed to the island to guard and protect the birds. A few naturalists visited Kroegel at Pelican Island, a curator at the American Museum of Natural History in New York, Frank Chapman, was one of the naturalists showing interest in the island as well. He discovered that Pelican Island was one of the last rookeries of Brown pelicans on the eastern coast of Florida, the American Ornithologists Union and the Florida Audubon Society led a campaign to pass legislation for protection of non-game birds in 1901. Kroegel was hired by the Florida Audubon Society to protect the birds from the game hunters. Knowing that the protection of Pelican Island would require legislation, Chapman and his fellow advocate. The two appealed their case to Roosevelt’s conservative ethics, President Roosevelt signed an executive order that established Pelican Island as the first federal bird reservation. This was the first time that the government put land aside for the sake of wildlife. The area, however, was open for big game hunters, during the 1960s, Pelican Island was threatened by attempts to sell the surrounding wetlands and islands to developers. Local citizens led a fight to protect Pelican Island by stopping the sale of the wetlands, in 1968, Florida agreed to expand to include nearly 5000 acres of mangrove islands and other submerged lands. And then in 1970, Pelican Island became the smallest wilderness area in the National Wilderness Preservation System, Pelican Island National Wildlife Refuge was added to the list of wetlands of international importance under the Ramsar Convention signed in 1971

Hunting
–
Hunting is the practice of killing or trapping animals, or pursuing or tracking them with the intent of doing so. Hunting wildlife or feral animals is most commonly done by humans for food, recreation, to predators that are dangerous to humans or domestic animals. Lawful hunting is distinguished from poaching, which is the killing, trapping or capture of the hunted species. The species that are hunted are referred to as game or prey and are usually mammals, Hunting can also be a means of pest control. However, hunting has also contributed to the endangerment, extirpation and extinction of many animals. The pursuit, capture and release, or capture for food of fish is called fishing, the practice of foraging or gathering materials from plants and mushrooms is also considered separate from hunting. The word hunt serves as both a noun and a verb, the noun has been dated to the early 12th century, act of chasing game, from the verb hunt. The meaning of a body of persons associated for the purpose of hunting with a pack of hounds is first recorded in the 1570s, meaning the act of searching for someone or something is from about 1600. The verb, Old English huntian to chase game, perhaps developed from hunta hunter, is related to hentan to seize, from Proto-Germanic huntojan, the general sense of search diligently is first recorded c. Hunting has a history and may well pre-date the rise of the species Homo sapiens. Evidence from western Kenya suggests that hunting has been occurring for more two million years. Furthermore, evidence exists that hunting may have one of the multiple environmental factors leading to the Holocene extinction of megafauna. North American megafauna extinction was coincidental with the Younger Dryas impact event, however, in other locations such as Australia, humans are thought to have played a very significant role in the extinction of the Australian megafauna that was widespread prior to human occupation. The closest surviving relatives of the species are the two species of Pan, the common chimpanzee and bonobos. Common chimpanzees have a diet that includes troop hunting behaviour based on beta males being led by an alpha male. Bonobos have also observed to occasionally engage in group hunting. With the establishment of language, culture, and religion, hunting became a theme of stories and myths, as well as such as dance. Hunting was a component of hunter-gatherer societies before the domestication of livestock

Fishing
–
Fishing is the activity of trying to catch fish. Fish are normally caught in the wild, techniques for catching fish include hand gathering, spearing, netting, angling and trapping. Fishing may include catching aquatic animals other than fish, such as molluscs, cephalopods, crustaceans, the term is not normally applied to catching farmed fish, or to aquatic mammals, such as whales where the term whaling is more appropriate. According to United Nations FAO statistics, the number of commercial fishermen. Fisheries and aquaculture provide direct and indirect employment to over 500 million people in developing countries, in 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms. In addition to providing food, modern fishing is also a recreational pastime, Fishing is an ancient practice that dates back to at least the beginning of the Upper Paleolithic period about 40,000 years ago. Isotopic analysis of the remains of Tianyuan man, a 40. Archaeology features such as middens, discarded fish bones, and cave paintings show that sea foods were important for survival. During this period, most people lived a lifestyle and were, of necessity. However, where there are examples of permanent settlements such as those at Lepenski Vir. The British dogger was a type of sailing trawler from the 17th century. The Brixham trawler that evolved there was of a build and had a tall gaff rig. They were also sufficiently robust to be able to tow large trawls in deep water, the great trawling fleet that built up at Brixham, earned the village the title of Mother of Deep-Sea Fisheries. The small village of Grimsby grew to become the largest fishing port in the world by the mid 19th century, an Act of Parliament was first obtained in 1796, which authorised the construction of new quays and dredging of the Haven to make it deeper. It was only in the 1846, with the expansion in the fishing industry. The foundation stone for the Royal Dock was laid by Albert the Prince consort in 1849, the dock covered 25 acres and was formally opened by Queen Victoria in 1854 as the first modern fishing port. The elegant Brixham trawler spread across the world, influencing fishing fleets everywhere, by the end of the 19th century, there were over 3,000 fishing trawlers in commission in Britain, with almost 1,000 at Grimsby. These trawlers were sold to fishermen around Europe, including from the Netherlands, twelve trawlers went on to form the nucleus of the German fishing fleet

Birdwatching
–
Birdwatching, or birding, is a form of wildlife observation in which the observation of birds is a recreational activity. It can be done with the eye, through a visual enhancement device like binoculars and telescopes, by listening for bird sounds. Birdwatching often involves a significant auditory component, as bird species are more easily detected and identified by ear than by eye. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, the first recorded use of the term birdwatcher was in 1891, bird was introduced as a verb in 1918. The term birding was also used for the practice of fowling or hunting with firearms as in Shakespeares The Merry Wives of Windsor and her husband goes this morning a-birding. The terms birding and birdwatching are today used by some interchangeably, although some participants prefer birding, in North America, many birders differentiate themselves from birdwatchers, and the term birder is unfamiliar to most lay people. At the most basic level, the distinction is perceived as one of dedication or intensity, generally, self-described birders perceive themselves to be more versed in minutiae like identification, molt, distribution, migration timing, and habitat usage. Indeed, in 1969 a Birding Glossary appeared in Birding magazine which gave the following definitions, the acceptable term used to describe the person who seriously pursues the hobby of birding. A hobby in which individuals enjoy the challenge of bird study, listing, a rather ambiguous term used to describe the person who watches birds for any reason at all, and should not be used to refer to the serious birder. Twitching is a British term used to mean the pursuit of a previously located rare bird, in North America it is more often called chasing, though the British usage is starting to catch on there, especially among younger birders. The term twitcher, sometimes misapplied as a synonym for birder, is reserved for those who travel long distances to see a bird that would then be ticked. The term originated in the 1950s, when it was used for the behaviour of Howard Medhurst. Prior terms for those who chased rarities were pot-hunter, tally-hunter, the main goal of twitching is often to accumulate species on ones lists. Some birders engage in competition to accumulate the longest species list, the act of the pursuit itself is referred to as a twitch or a chase. A rare bird that stays put long enough for people to see it is twitchable or chaseable, twitching is highly developed in the United Kingdom, the Netherlands, Denmark, Ireland, Finland and Sweden. The size of these makes it possible to travel throughout them quickly. The most popular twitches in the UK have drawn large crowds, for example, approximately 2,500 people travelled to Kent, England, to view a golden-winged warbler, twitchers have developed their own vocabulary. For example, a twitcher who fails to see a bird has dipped out, if other twitchers do see the bird

Photography
–
Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic sensor, this produces an electrical charge at each pixel. A negative image on film is used to photographically create a positive image on a paper base, known as a print. The word photography was created from the Greek roots φωτός, genitive of φῶς, light and γραφή representation by means of lines or drawing, several people may have coined the same new term from these roots independently. Johann von Maedler, a Berlin astronomer, is credited in a 1932 German history of photography as having used it in an article published on 25 February 1839 in the German newspaper Vossische Zeitung. Both of these claims are now widely reported but apparently neither has ever been confirmed as beyond reasonable doubt. Credit has traditionally given to Sir John Herschel both for coining the word and for introducing it to the public. Photography is the result of combining several technical discoveries, later Greek mathematicians Aristotle and Euclid also independently described a pinhole camera in the 5th and 4th centuries BCE. Daniele Barbaro described a diaphragm in 1566, wilhelm Homberg described how light darkened some chemicals in 1694. The fiction book Giphantie, published in 1760, by French author Tiphaigne de la Roche, the discovery of the camera obscura that provides an image of a scene dates back to ancient China. Leonardo da Vinci mentions natural camera obscura that are formed by dark caves on the edge of a sunlit valley, a hole in the cave wall will act as a pinhole camera and project a laterally reversed, upside down image on a piece of paper. So the birth of photography was primarily concerned with inventing means to capture, renaissance painters used the camera obscura which, in fact, gives the optical rendering in color that dominates Western Art. The camera obscura literally means dark chamber in Latin and it is a box with a hole in it which allows light to go through and create an image onto the piece of paper. Around the year 1800, British inventor Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance and he used paper or white leather treated with silver nitrate. The shadow images eventually darkened all over, the first permanent photoetching was an image produced in 1822 by the French inventor Nicéphore Niépce, but it was destroyed in a later attempt to make prints from it. Niépce was successful again in 1825, in 1826 or 1827, he made the View from the Window at Le Gras, the earliest surviving photograph from nature. Because Niépces camera photographs required a long exposure, he sought to greatly improve his bitumen process or replace it with one that was more practical. With an eye to eventual commercial exploitation, the partners opted for total secrecy, Daguerres efforts culminated in what would later be named the daguerreotype process

Climate change
–
Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time. Climate change may refer to a change in weather conditions. Climate change is caused by such as biotic processes, variations in solar radiation received by Earth, plate tectonics. Certain human activities have also identified as significant causes of recent climate change. Scientists actively work to understand past and future climate by using observations, more recent data are provided by the instrumental record. The most general definition of change is a change in the statistical properties of the climate system when considered over long periods of time. Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, the term climate change is often used to refer specifically to anthropogenic climate change. Anthropogenic climate change is caused by activity, as opposed to changes in climate that may have resulted as part of Earths natural processes. In this sense, especially in the context of environmental policy, within scientific journals, global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas levels affect. A related term is climatic change, in 1966, the World Meteorological Organization proposed the term climatic change to encompass all forms of climatic variability on time-scales longer than 10 years, regardless of cause. Change was a given and climatic was used as an adjective to describe this kind of change, when it was realized that human activities had a potential to drastically alter the climate, the term climate change replaced climatic change as the dominant term to reflect an anthropogenic cause. Climate change was incorporated in the title of the Intergovernmental Panel on Climate Change, Climate change, used as a noun, became an issue rather than the technical description of changing weather. On the broadest scale, the rate at which energy is received from the Sun and this energy is distributed around the globe by winds, ocean currents, and other mechanisms to affect the climates of different regions. Factors that can shape climate are called climate forcings or forcing mechanisms, there are a variety of climate change feedbacks that can either amplify or diminish the initial forcing. Some parts of the system, such as the oceans and ice caps, respond more slowly in reaction to climate forcings. There are also key factors which when exceeded can produce rapid change. Forcing mechanisms can be internal or external. Internal forcing mechanisms are natural processes within the system itself

Invasive species
–
One study pointed out widely divergent perceptions of the criteria for invasive species among researchers and concerns with the subjectivity of the term invasive. Such invasive species may be either plants or animals and may disrupt by dominating a region, wilderness areas, particular habitats and this includes non-native invasive plant species labeled as exotic pest plants and invasive exotics growing in native plant communities. It has been used in this sense by government organizations as well as groups such as the International Union for Conservation of Nature. The European Union defines Invasive Alien Species as those that are, firstly, outside their natural distribution area and it is also used by land managers, botanists, researchers, horticulturalists, conservationists, and the public for noxious weeds. The kudzu vine, Andean Pampas grass, and yellow starthistle are examples, an alternate usage broadens the term to include indigenous or native species along with non-native species, that have colonized natural areas. Deer are an example, considered to be overpopulating their native zones and adjacent suburban gardens, by some in the Northeastern, sometimes the term is used to describe a non-native or introduced species that has become widespread. However, not every introduced species has adverse effects on the environment, a nonadverse example is the common goldfish, which is found throughout the United States, but rarely achieves high densities. Scientists include species and ecosystem factors among the mechanisms that when combined, while all species compete to survive, invasive species appear to have specific traits or specific combinations of traits that allow them to outcompete native species. In some cases, the competition is about rates of growth, in other cases, species interact with each other more directly. Researchers disagree about the usefulness of traits as invasiveness markers, one study found that of a list of invasive and noninvasive species, 86% of the invasive species could be identified from the traits alone. Another study found invasive species tended to have only a subset of the presumed traits. Repeated patterns of movement, such as ships sailing to and from ports or cars driving up. An introduced species might become if it can outcompete native species for resources such as nutrients, light, physical space, water. If these species evolved under great competition or predation, then the new environment may host fewer able competitors, allowing the invader to proliferate quickly. Ecosystems in which are being used to their fullest capacity by native species can be modeled as zero-sum systems in which any gain for the invader is a loss for the native, however, such unilateral competitive superiority is not the rule. For example, barbed goatgrass was introduced to California on serpentine soils, which have low water-retention, low nutrient levels, a high magnesium/calcium ratio, and possible heavy metal toxicity. Plant populations on these soils tend to low density, but goatgrass can form dense stands on these soils. Some species, like Kalanchoe daigremontana, produce allelopathic compounds, that might have an effect on competing species

Endangered species
–
An endangered species is a species which has been categorized as likely to become extinct. In 2012, the IUCN Red List featured 3079 animal and 2655 plant species as endangered worldwide, the figures for 1998 were, respectively,1102 and 1197. Many nations have laws that protect conservation-reliant species, for example, population numbers, trends and species conservation status can be found in the lists of organisms by population. The conservation status of a species indicates the likelihood that it will become extinct, the IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. Over 40% of the species are estimated to be at risk of extinction. Internationally,199 countries have signed an accord to create Biodiversity Action Plans that will protect endangered, in the United States, such plans are usually called Species Recovery Plans. Those species of Near Threatened and Least Concern status have been assessed and found to have relatively robust and healthy populations, though these may be in decline. The IUCN categories, with examples of animals classified by them, include, Extinct Extinct in the wild Captive individuals survive, critically endangered Faces an extremely high risk of extinction in the immediate future. Endangered Faces a high risk of extinction in the near future, vulnerable Faces a high risk of endangerment in the medium term. Near-threatened May be considered threatened in the near future, Least concern No immediate threat to species survival. A population size reduction of ≥ 50%, projected or suspected to be met within the next 10 years or three generations, whichever is the longer, based on any of to under A1. E) Quantitative analysis showing the probability of extinction in the wild is at least 20% within 20 years or five generations, there is data from the United States that shows a correlation between human populations and threatened and endangered species. Under the Endangered Species Act in the United States, species may be listed as endangered or threatened, the Salt Creek tiger beetle is an example of an endangered subspecies protected under the ESA. Some endangered species laws are controversial, also lobbying from hunters and various industries like the petroleum industry, construction industry, and logging, has been an obstacle in establishing endangered species laws. The Bush administration lifted a policy that required federal officials to consult an expert before taking actions that could damage endangered species. Under the Obama administration, this policy has been reinstated, being listed as an endangered species can have negative effect since it could make a species more desirable for collectors and poachers. This effect is potentially reducible, such as in China where commercially farmed turtles may be reducing some of the pressure to poach endangered species. Another problem with the species is its effect of inciting the use of the shoot, shovel
