Deforestation in British Columbia : ウィキペディア英語版 | Deforestation in British Columbia
Deforestation is the long-term removal of trees from a forested site to permit other site uses such as agriculture, urbanization, transportation and forestry processes. The deforestation in British Columbia has occurred at a heavy rate during periods of the past, but with new sustainable efforts and programs the rate of deforestation is decreasing in the province. In British Columbia, forests cover over 55 million hectares, which is 57.9% of British Columbia's 95 million hectares of land.〔(【引用サイトリンク】url=http://www.for.gov.bc.ca/hfp/sof/2010/SOF_2010_Web.pdf )〕 The forests are mainly composed (over 80%) of coniferous trees, such as pines, spruces and firs.〔(【引用サイトリンク】url=http://www.for.gov.bc.ca/hfp/sof/2010/SOF_2010_Web.pdf )〕 ==Environmental Issues==
Deforestation has negative impacts on British Columbia's environment and diversity even though it is necessary for population expansion and benefits for the Canadian economy.
