Charles Lewis Camp
Charles Lewis Camp (March 12, 1893 Jamestown, North Dakota – August 14, 1975 San Jose, California) was a palaeontologist and zoologist, working from the University of California, Berkeley. He took part in excavations at the 'Placerias Quarry', in 1930 and the forty ''Shonisaurus'' skeleton discoveries of the 1960s, in what is now the Berlin-Ichthyosaur State Park. Camp served as the third director of the University of California Museum of Paleontology from 1930 to 1949, and coincidentally as chair of the UC Berkeley Paleontology Department between 1939 and 1949. Camp named a number of species of marine reptiles such as ''Shonisaurus'' and ''Plotosaurus'', as well as the dinosaur '' Segisaurus''. Camp was also an important bibliographer and historian of Western America. This aspect of his career is represented most notably by two works. The first is his biography of American pioneer James Clyman, which Bernard De Voto called "one of the half-dozen classics in the field." The secon ...

Commerce Clause
The Commerce Clause describes an enumerated power listed in the United States Constitution ( Article I, Section 8, Clause 3). The clause states that the United States Congress shall have power "to regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes". Courts and commentators have tended to discuss each of these three areas of commerce as a separate power granted to Congress. It is common to see the individual components of the Commerce Clause referred to under specific terms: the Foreign Commerce Clause, the Interstate Commerce Clause, and the Indian Commerce Clause. Dispute exists within the courts as to the range of powers granted to Congress by the Commerce Clause. As noted below, it is often paired with the Necessary and Proper Clause, and the combination used to take a more broad, expansive perspective of these powers. During the Marshall Court era (1801–1835), interpretation of the Commerce Clause gave Congress jurisdiction ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Roberts
John Glover Roberts Jr. (born January 27, 1955) is an American lawyer and jurist who has served as the 17th chief justice of the United States since 2005. Roberts has authored the majority opinion in several landmark cases, including ''National Federation of Independent Business v. Sebelius,'' '' Shelby County v. Holder'', and '' Riley v. California''. He has been described as having a conservative judicial philosophy but, above all, is an institutionalist. He has shown a willingness to work with the Supreme Court's liberal bloc, and after the retirement of Anthony Kennedy in 2018, he has been regarded as the primary swing vote on the Court. However, Roberts is no longer regarded as the Court's median vote following the replacement of Ruth Bader Ginsburg by Amy Coney Barrett in 2020. Roberts grew up in northwestern Indiana and was educated in a series of Catholic schools. He studied history at Harvard University and then attended Harvard Law School, where he was managing e ...

Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

United States Secretary Of The Interior
The United States secretary of the interior is the head of the United States Department of the Interior. The secretary and the Department of the Interior are responsible for the management and conservation of most federal land along with natural resources, leading such agencies as the Bureau of Land Management, the United States Geological Survey, Bureau of Indian Affairs and the National Park Service.

Wildfire Suppression
Wildfire suppression is a range of firefighting tactics used to suppress wildfires. Firefighting efforts in wild land areas require different techniques, equipment, and training from the more familiar structure fire fighting found in populated areas. Working in conjunction with specially designed aerial firefighting aircraft, these wildfire-trained crews suppress flames, construct fire lines, and extinguish flames and areas of heat to protect resources and natural wilderness. Wildfire suppression also addresses the issues of the wildland–urban interface, where populated areas border with wild land areas. In the United States and other countries, aggressive wildfire suppression aimed at minimizing fire has contributed to accumulation of fuel loads, increasing the risk of large, catastrophic fires. History Australia Wildland fire, known in Australia as bush fire, has played a major role in Australia due to arid conditions. Notable fire services tasked with wildfire suppres ...

Invasive Plant
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...
