Environmental Issues In Brazil
Environmental issues in Brazil include deforestation, illegal wildlife trade, illegal poaching, air, land degradation, and water pollution caused by mining activities, wetland degradation, pesticide use and severe oil spills, among others. As the home to approximately 13% of all known species, Brazil has one of the most diverse collections of flora and fauna on the planet. Impacts from agriculture and industrialization in the country threaten this biodiversity. Deforestation Deforestation in Brazil is a major issue; the country once had the highest rate of deforestation in the world. By far the most deforestation comes from cattle ranchers that clear rainforest (sometimes illegally, sometimes legally), so as to make room for sowing grass and giving their cattle the ability to graze on this location. An important route taken by cattle ranchers and their cattle is the Trans-Amazonian Highway. Deforestation has been a significant source of pollution, biodiversity loss, and greenhou ...

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 ...

Environmental Impact Of Reservoirs
The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water, generate hydroelectric power, increase the water supply for irrigation, provide recreational opportunities, and flood control. In 1960 the construction of Llyn Celyn and the flooding of Capel Celyn provoked political uproar which continues to this day. More recently, the construction of Three Gorges Dam and other similar projects throughout Asia, Africa and Latin America have generated considerable environmental and political debate. Currently, 48 percent of rivers and their hydro-ecological systems are affected by reservoirs and dams. Upstream impacts Fragmentation of river ecosystems A dam acts as a barrier between the upstream and downstream movement of migratory river animals, such as salmon and trout. Some communities have also begun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landfill Gas
Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste. Landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide. Trace amounts of other volatile organic compounds (VOCs) comprise the remainder (<1%). These trace gases include a large array of species, mainly simple s.Hans-Jürgen Ehrig, Hans-Joachim Schneider and Volkmar Gossow "Waste, 7.

Municipal Solid Waste
Municipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.' Composition The composition of municipal solid waste varies greatly from municipality to municipality, and it changes significantly with time. In municipalities which have a well-developed waste recycling system, the waste stream mainly consists of intractable wastes such as plastic film and non-recyclab ...

Waste-to-energy
Waste-to-energy (WtE) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste, or the processing of waste into a fuel source. WtE is a form of energy recovery. Most WtE processes generate electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels. History The first incinerator or "Destructor" was built in Nottingham, UK, in 1874 by Manlove, Alliott & Co. Ltd. to the design of Alfred Fryer. The first US incinerator was built in 1885 on Governors Island in New York, New York. The first waste incinerator in Denmark was built in 1903 in Frederiksberg.Waste to Energy in Denmark by Ramboll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waste Management
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, economic mechanisms. Waste can be solid, liquid, or gases and each type has different methods of disposal and management. Waste management deals with all types of waste, including industrial, biological, household, municipal, organic, biomedical, radioactive wastes. In some cases, waste can pose a threat to human health. Health issues are associated throughout the entire process of waste management. Health issues can also arise indirectly or directly. Directly, through the handling of solid waste, and indirectly through the consumption of water, soil and food. Waste is produced by human activity, for example, the extraction and processing of raw materi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
