Examples of habitat destruction include deforestation, filling wetlands and mowing fields. Habitat loss or destruction caused by population growth and expansion and the needs of people on the planet lead to loss of plant and animal species.Know More
Agricultural needs drive much of the habitat loss in the United States. To grow more crops, lands are clear cut, wetlands are filled, and prairie grasses are cut so the land can be cultivated. Excessive grazing of cattle and over-fishing also damage habitats on the land and in water. Changes to the area's natural water system for crop irrigation also cause habitat destruction.
Development of previously unused lands causes a great deal of habitat loss. Forests are cut down, fields are cut and stripped of their grasses, and flowers and animals are blocked from their natural habitats by roads and shopping malls. Logging may start the destruction process, and building high-rise apartments or strip malls furthers the habitat loss.
The use of water, and meeting the needs of the growing population, leads to habitat destruction. Dams change the flow of rivers, changing the ecology downstream. Diverting water for human use and pollution from cities and farms have a serious impact on the habitats around the water source. The water chemistry changes, the water level is altered, and the habitats and ecosystems downstream can be destroyed.Learn more about Human Impact
Examples of man-made disasters, which result from human negligence, error or intent, include nuclear warfare, biochemical warfare, nuclear explosions, toxic emissions, global warming, fires, civil unrest and terrorism. Man-made disasters can be catastrophic, causing extensive damage to the environment and resulting in human loss and devastation.Full Answer >
Several types of habitats are found in the world, including forests, meadows or fields, thickets, marshes, ponds, forest streams, rivers, forest edges, flower gardens and even neighborhood streets. A habitat is a place where any organism or biological population lives or occurs.Full Answer >
The National Aeronautics and Space Administration lists agricultural expansion, wood harvest, urbanization and infrastructure creation as the direct causes of deforestation. Converting forested lands for agricultural use is by far the largest cause of deforestation. Conversion to agricultural lands primarily occurs in developing nations and is carried out by subsistence farmers, while other types of deforestation are triggered by economic growth.Full Answer >
The Keystone Pipeline brings oil from Alberta, Canada to oil refineries in the U.S. Midwest and the Gulf Coast of Texas. The pipeline is owned by TransCanada, who first proposed the pipeline in 2005. It was approved by the U.S. Department of State in 2008 and began operations in 2010.Full Answer >
