Logging In The United States
In the United States, deforestation was an ongoing process until recently. Between 2010 and 2020, the US forests increased 0.03% annually, according to FAO (Food and Agriculture Organization of the United Nations). Native Americans cleared millions of acres of forest for many reasons, including hunting, farming, berry production, and building materials. Prior to the arrival of European-Americans, about one half of the United States land area was forest, about estimated in 1630. Forest cover in the Eastern United States reached its lowest point in roughly 1872 with about 48 percent compared to the amount of forest cover in 1620. The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as around 1920. The forest resources of the United States remained relatively constant through the 20th century. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Passenger Pigeon
The passenger pigeon or wild pigeon (''Ectopistes migratorius'') is an extinct species of pigeon that was endemic to North America. Its common name is derived from the French word ''passager'', meaning "passing by", due to the migratory habits of the species. The scientific name also refers to its migratory characteristics. The morphologically similar mourning dove (''Zenaida macroura'') was long thought to be its closest relative, and the two were at times confused, but genetic analysis has shown that the genus '' Patagioenas'' is more closely related to it than the ''Zenaida'' doves. The passenger pigeon was sexually dimorphic in size and coloration. The male was in length, mainly gray on the upperparts, lighter on the underparts, with iridescent bronze feathers on the neck, and black spots on the wings. The female was , and was duller and browner than the male overall. The juvenile was similar to the female, but without iridescence. It mainly inhabited the deciduous fores ...

Environmental Issues In The United States
Environmental issues in the United States include climate change, energy, species conservation, invasive species, deforestation, mining, nuclear accidents, pesticides, pollution, waste and over-population. Despite taking hundreds of measures, the rate of environmental issues is increasing rapidly instead of reducing. The United States is among the most significant emitters of greenhouse gasses in the world. In terms of both total and per capita emissions, it is among the largest contributors. The climate policy of the United States has big influence on the world. Movements and ideas 20th century Botconservationismand environmentalism appeared in political debate in forests about the Progressive Era in the early 20th century. There were three main positions. The laissez-faire position held that owners of private property—including lumber and mining companies, should be allowed to do anything they wished for their property.

Environment Of The United States
The environment of the United States comprises diverse biotas, climates, and geologies. This diversity leads to a number of different distinct regions and geographies in which human communities live. This includes a rich variety of species of both animals other fauna, and flora. Because of the strong forces of economic exploitation and industrialization, human's have had deep effects on the ecosystems of the United States, resulting in a number of environmental issues. Since awareness of these issues emerged in the 1970s, environmental regulations and a growing environmental movement, including both climate movement and the environmental justice movement have emerged to respond to the various threats to the environment. These movements are intertwined with a long history of conservation, starting in the early 19th century, that has resulted in a robust network of protected areas, including 28.8% of land managed by the Federal government.

Deforestation By Region
Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Russia, Brazil, Canada, The United States, China, Australia, The Democratic Republic of the Congo, Indonesia, India, and Peru.Al Gore: Our Choice, A plan to solve the climate crises, Bloomsbury 2009, Chapter 9 Forests 170-195; pages 174, 192, 184, 186, 192, 172 Global annual deforestation is estimated at 13.7 million hectares a year, equal to the area of Greece. Half of this area is compensated by new forests or forest growth. In addition to direct human-induced deforestation, growing forests have also been affected by climate change. The Kyoto protocol includes the agreement to prevent deforestation, but not the actions to fulfil it. Global analysis An analysis of global deforestation patterns in 2021 showed that patterns of trade, production and consumption are driving rates in complex ways. While the location of defor ...

Conservation Movement
The conservation movement, also known as nature conservation, is a political, environmental, and social movement that seeks to manage and protect natural resources, including animal, fungus, and plant species as well as their habitat for the future. Conservationists are concerned with leaving the environment in a better state than the condition they found it in. Evidence-based conservation seeks to use high quality scientific evidence to make conservation efforts more effective. The early conservation movement evolved out of necessity to maintain natural resources such as fisheries, wildlife management, water, soil, as well as conservation and sustainable forestry. The contemporary conservation movement has broadened from the early movement's emphasis on use of sustainable yield of natural resources and preservation of wilderness areas to include preservation of biodiversity. Some say the conservation movement is part of the broader and more far-reaching environmental movem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bachman's Warbler
Bachman's warbler (''Vermivora bachmanii'') is a likely extinct passerine migratory bird. This warbler was a migrant, breeding in swampy blackberry and cane thickets of the Southeastern and Midwestern United States and wintering in Cuba. There are some reports of the bird from the twenty-first century, but none are widely accepted. Some authorities accept a sighting in Louisiana, in August 1988 as confirmed, but the last uncontroversial sightings date to the 1960s. Taxonomy This bird was first recorded in 1832 by the Reverend John Bachman, who found the species near Charleston, South Carolina, and presented study skins and descriptions to his friend and collaborator, John James Audubon. Audubon never saw the bird alive but named it in honor of Bachman in 1833. The blue-winged and rapidly declining golden-winged warblers, also members of the genus ''Vermivora'', are thought to be this warbler's closest relatives. There are no known subspecies.

Ivory-billed Woodpecker
The ivory-billed woodpecker (''Campephilus principalis'') is a possibly extinct woodpecker that is native to the bottomland hardwood forests and temperate coniferous forests of the Southern United States and Cuba. Habitat destruction and hunting have reduced populations so thoroughly that the species is listed by the International Union for Conservation of Nature (IUCN) on its IUCN Red List, Red List as critically endangered, and by the American Birding Association as "definitely or probably extinct". The last universally accepted sighting of an American ivory-billed woodpecker occurred in Louisiana in 1944, and the last universally accepted sighting of a Cuban ivory-billed woodpecker occurred in 1987, after the bird's rediscovery there the prior year. Sporadic reports of sightings and other evidence of the persistence of the species have continued since then. The bird's preferred diet consists of large beetle larvae, particularly wood-boring Cerambycidae beetles, supplemented by ...

Carolina Parakeet
The Carolina parakeet (''Conuropsis carolinensis''), or Carolina conure, is an extinct species of small green neotropical parrot with a bright yellow head, reddish orange face and pale beak that was native to the eastern, Midwest and plains states of the United States. It was the only indigenous parrot within its range, as well as one of only three parrot species native to the United States (the others being the thick-billed parrot, now extirpated, and the green parakeet, still present in Texas; a fourth parrot species, the red-crowned amazon, is debated). The Carolina parakeet was found from southern New York and Wisconsin to Kentucky, Tennessee and the Gulf of Mexico, from the Atlantic seaboard to as far west as eastern Colorado. It lived in old-growth forests along rivers and in swamps. It was called ''puzzi la née'' ("head of yellow") or ''pot pot chee'' by the Seminole and ''kelinky'' in Chickasaw. Though formerly prevalent within its range, the bird had become rare by the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...
