Pressing Environmental Issues in Manitoba - Essay Example ManitobaÃ¢â¬â¢s mining industry is currently worth over $2.5 billion with peat, zinc, silver, gold, copper, platinum, cobalt and nickel being the major metal products of this sector. Mining has however been a major threat to terrestrial biodiversity in Manitoba through land conversions and pollution (Wellington, 1997). A key environmental concern in mining has always centered on the rehabilitation of old, orphaned mines which consist of steep excavations, shafts and exploration trenches. Despite mining being a key revenue generator for ManitobaÃ¢â¬â¢s government, public safety has been compromised after abandoned mines are left unattended since such mines pose a threat to local communities living nearby. The Mine Closure Regulation which was approved in 1999 led to the establishment of The Orphaned and Abandoned Mines Program (OAMS) mandated to deal with such mines by sealing them using Otto BayerÃ¢â¬â¢s Polyurethane foam (PUF) technology (Priscu et al, 2009). Many of these aba ndoned sites are situated within the Precambrian Shield which has massive gold deposits. Provincial Parks, aquatic life and areas with dense vegetation have not been spared due to discovery of more valuable metal deposits under them which eventually results in encroachment by the mining industry. Industry plays a major part in ManitobaÃ¢â¬â¢s development. However, hazardous waste mainly originates from ManitobaÃ¢â¬â¢s industries and exhibit a variety of harmful radiological, corrosive, bio hazardous, explosive and toxic properties.
