Logging Impacts

Gina Teo writes:*

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.

#0350# The blog give me a logically idea about the harm which is caused by excessive logging. Also the author connected the Environment with the Economics together is a good idea to let the audience realize the importance about the forest. But, as this is a blog,people won't pay much more attention to read the words one by one, I would suggest you to list more disadvantages of logging, but you do not need to analyze point to point.

I agree with the blog that trying to tell us the future cost or what we called "future negative externalities" is included from excess logging.
As the blog had mentioned about the road construction separates the forest which creates species migration, I totally agree with this.
I'm sure not everyone will be aware the potential threat on the road we using after the re-construction such as road expanding, for example the road on the way to whistler, could danger our life when we go for a trip and pass by due to the trees got chop down, big rocks got taken away along with the trees and land causing the environment imbalance and etc which eventually turning the harms back to our life.
What I want to say from my example above is that it’s better to mention about something harmful that recently happen from excessive logging so that the others would be aware of instead of thinking the impact of logging won’t be happen within 50 years or later so they won’t be paying any attention to it.

I like your post. Its logic is very clear. You put enough information, data and analysis in which I think is very helpful.
But I suggest you to clarify your title to be"over logging impact" and bottom line to be "over logging have negative impacts to ecosystem". Since trees are renewable resource, if logging is good managed, it can generate benefits. The problems you are talking is due to over logging.
Hope my suggestion is helpful.

Thanks all the comments. As this is my first blog post, so your comments are important for me, it help me to improve my writing skill and what kind of information should and should not include in the post, and also thank for the suggestion about the title.
