What are the negative effects of clear-cut timbering in Canada, and what has the government and timber industry done to solve these problems?

There are negative results of clear-cutting, from loss of habitat to an elevation in stream temperatures which can cause fish to die off, but all of them reflect major changes that can take decades to correct. Numerous activists have suggested more environmentally sustainable alternatives to clearcutting, such as selective logging, and hope that as more consumers become aware of the potential dangers of clearcutting, they will seek out sustainably-harvested timber.
