Which of the following is not a way humans have impacted the tundra? a. oil drilling b. logging c. overgrazing d. mining

Option (B)- Logging

Explanation:

The humans have not impacted the tundra by carrying out the logging activity as in the tundra region, there is significantly less number of trees and the temperature is relatively very cold and most of the time the land areas are covered with snow and ice. This covers the regions of higher latitudes, extending from about 60 degrees up to the poles in both the hemisphere. Due to this less abundance of trees, the logging activity is not carried out in this particular region.

Further explanation:

Logging is defined as the activity where the trees are cut down and processed and are transported to the site where they are extensively used in order to make materials such as furniture, manufacturing of paper and other products.

The tundra region is usually characterised by the presence of the permafrost layer, which is a permanently frozen layer present under the surface of the earth. They are made up of materials such as soil, sand, gravel that are accumulated together by ice.

This logging activity has a direct effect on the atmosphere. It is because the deforestation process causes a reduction in the number of trees, as a result of which the CO2 present in the atmosphere will increase the global temperature of the earth, thereby causing the greenhouse effect. Increasing logging activity also leads to soil erosion and degradation of the soil quality.

Due to the absence of the trees, the tundra region is not affected by the logging activity.
