The Australian environment ranges from virtually pristine Antarctic territory and rainforests to degraded industrial areas of major cities. 40 distinct ecoregions have been identified across the Australian mainland and islands. Central Australia has a very dry climate. The interior has a number of deserts while most of the coastal areas are populated. Northern Australia experiences tropical cyclones while much of the country is prone to periodic drought. Agriculture and mining are the predominant land uses which affect the Australian environment. The management of the impact on the environment from the mining industry, the protection of the Great Barrier Reef, forests and native animals are recurring issues of conservation. Clean Up Australia Day was an initiative developed in 1989 to collaboratively clean up local areas and is held on the first Sunday of autumn (in March). == Issues == (詳細はwhaling, logging of old growth forest, irrigation and its impact on the Murray River, Darling River and Macquarie Marshes, acid sulfate soils, soil salinity, land clearing, soil erosion, uranium mining and nuclear waste, creation of marine reserves,〔http://www.nccnsw.org.au/index.php?option=com_content&task=blogcategory&id=64&Itemid=602〕 air quality in major cities and around polluting industries and infrastructure, pesticide and herbicide impacts and growing of genetically modified food. Increased coal mining in Australia is contentious because of the effects of global warming on Australia, emissions to air from coal burning power stations, dust, subsidence, impact on rivers like the Hunter River and other water users, failure to adequately restore mined areas, and lack of sustainability. As an example, in 1999 Australia's energy consumption of coal and coal products was 47,364 thousand metric tons oil equivalent,〔http://courses.washington.edu/envir100/town_hall/australia.pdf〕 compared to that of the world's energy consumption of coal and coal products which totalled 2,278,524 (also measured in thousand metric tons oil equivalent). Climate change and global warming are of particular concern because of the likely effects of global warming on agriculture, the Great Barrier Reef and tourism industry, human health through mosquito borne crydiologicyticlogy.〔()〕 Sea level rise could also have a profound impact on under levelled and poorer communities and waterfront suburbs. The range of rises forecast by the IPCC Fourth Assessment Report would be sufficient to have impacts in many areas, and if the Greenland ice cap melts faster than forecast, it could have a disastrous impact. In urban areas noise and odour are major sources of complaints to environmental protection authorities. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Environment of Australia」の詳細全文を読む スポンサード リンク
