Deforestation | Wikipedia audio article

This is an audio version of the Wikipedia Article: Deforestation Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

Examples of deforestation include conversion of forestland to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31 percent of Earth's land surface is covered by forests.Deforestation occurs for multiple reasons: trees are cut down to be used for building or sold as fuel (sometimes in the form of charcoal or timber), while cleared land is used as pasture for livestock and plantation. The removal of trees without sufficient reforestation has resulted in habitat damage, biodiversity loss, and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide. Deforestation has also been used in war to deprive the enemy of vital resources and cover for its forces. Modern examples of this were the use of Agent Orange by the British military in Malaya during the Malayan Emergency and the United States military in Vietnam during the Vietnam War. As of 2005, net deforestation rates have ceased to increase in countries with a per capita GDP of at least US$4,600. Deforested regions typically incur significant adverse soil erosion and frequently degrade into wasteland. Disregard of ascribed value, lax forest management, and deficient environmental laws are some of the factors that allow deforestation to occur on a large scale. In many countries, deforestation–both naturally occurring and human-induced–is an ongoing issue. Deforestation causes extinction, changes to climatic conditions, desertification, and displacement of populations as observed by current conditions and in the past through the fossil record. More than half of all plant and land animal species in the world live in tropical forests.Between 2000 and 2012, 2.3 million square kilometres (890,000 sq mi) of forests around the world were cut down. As a result of deforestation, only 6.2 million square kilometres (2.4 million square miles) remain of the original 16 million square kilometres (6 million square miles) of forest that formerly covered the Earth. An area the size of a football pitch is cleared from the Amazon rainforest every minute, with 136 million acres (55 million hectares) of rainforest cleared for animal agriculture overall.

Located in the city of Berkeley, it was founded in 1868, and serves as the flagship institution of the ten research universities affiliated with the University of California system. Berkeley has since grown to instruct over 40,000 students in approximately 350 undergraduate and graduate degree programs covering numerous disciplines.Berkeley is one of the 14 founding members of the Association of American Universities, with $789 million in R&D expenditures in the fiscal year ending June 30, 2015. Today, Berkeley maintains close relationships with three United States Department of Energy National Laboratories—Lawrence Berkeley National Laboratory, Lawrence Livermore National Laboratory and Los Alamos National Laboratory—and is home to many institutes, including the Mathematical Sciences Research Institute and the Space Sciences Laboratory. Through its partner institution University of California, San Francisco (UCSF), Berkeley also offers a joint medical program at the UCSF Medical Center.As of October 2018, Berkeley alumni, faculty members and researchers include 107 Nobel laureates, 25 Turing Awards winners, and 14 Fields Medalists. They have also won 9 Wolf Prizes, 45 MacArthur Fellowships, 20 Academy Awards, 14 Pulitzer Prizes and 207 Olympic medals (117 gold, 51 silver and 39 bronze). In 1930, Ernest Lawrence invented the cyclotron at Berkeley, based on which UC Berkeley researchers along with Berkeley Lab have discovered or co-discovered 16 chemical elements of the periodic table – more than any other university in the world. During the 1940s, Berkeley physicist J. R. Oppenheimer, the "Father of the Atomic Bomb", led the Manhattan project to create the first atomic bomb. In the 1960s, Berkeley was particularly noted for the Free Speech Movement as well as the Anti-Vietnam War Movement led by its students. In the 21st century, Berkeley has become one of the leading universities in producing entrepreneurs and its alumni have founded a large number of companies worldwide.Berkeley is often ranked as a top-ten university in the world and as the top public university in the United States. For 2017–18, the Academic Ranking of World Universities (ARWU) ranked Berkeley 5th in the world. Berkeley also ranks 6th internationally in the CWUR World University Rankings. It is additionally ranked 4th in the world by U.S. News & World Report. Berkeley is ra ...
