Canada is the second largest forest products exporter in the world; 10% of the world’s forests are distributed in Canada. The forest industries earn approximate 2% of Canada GPD per year. As the highly demand of forest product, industry excessive logging causes negative impacts to environment.
The road constructions during the logging operation have direct impacts to the wildlife, the ecological system in the forestry and the aquatic health. The road constructions separate the forests therefore create barriers for the species migration, when the wildlife unable to cross the barriers will change their distribution, eventually will cause severe consequences on the local scale. The road constructions also lead to compacted soil. Soil compacted will decrease water and oxygen available for the agriculture, lack of water and oxygen cause plant difficult to growth. The soil compacted can destroy the organic layers in the land and accelerate the soil erosion; it also restricts the plant’s root growth and decline the nutrients absorb by the plant.
Logging activities have a lot of impacts on aquatic systems too. Over logging can cause sedimentation, erosion and change the rive flow patterns. Logging lead to high volumes of soil slide into river, therefore change the natural river flow patterns. The soil slide into the water may decrease the fish survival rate as the fine sediment and the water temperature increase. The deposit of soil in the water will destroy the fish’s spawning area and the refuge habitat.
Although the forest industry bring a lot of profit to the economic, but people should care about the environment too.
Bottom Line Logging have negative impacts to the ecosystem.
