The Federation of Northern Ontario Municipalities says environmentalists ignore that climate change is a threat to the caribou.  Instead FONOM and the Northwestern Ontario Municipal Association say these groups keep blaming the forest sector for the caribou drop.   However both lobby groups say the caribou population has actually been rising thanks to sound practices.  FONOM says instead of criticizing forestry, environmentalists should consider a research paper that says changes in winter temperatures could reduce caribou numbers by 2050.  The lobby groups say the information is found in the research journal Rangifer and details how winter changes could cause a significant drop in the caribou population. …The lobby groups say instead of looking at these results, the environmental groups continue to try and shut down forestry which is both a renewable and sustainable industry.
