Terrestrial impacts arise from the removal of mountaintops and the forests that cover them. They include the loss of topographic complexity, forest loss and fragmentation, the impact of soil loss on forest succession, the impact of forest loss on carbon sequestration, changes in biological diversity, and impacts on human health and well-being.

5.0 MITIGATION OF ENVIRONMENTAL IMPACTS OF FOREST INDUSTIRES. The most critical environmental impact of the activities of forest industries that require urgent attention is the destruction of forest cover. Over the years, much exploitation of the forest has been done in order to meet the increasing demand of the teeming population.

During this course of action often lands under the cover of forest or agriculture are diverted for mining.
Forest degradation, although widespread, often goes unnoticed Box 1. For example, standard forest cover definitions will fail to capture changes in forests above 10 percent canopy cover Fig. 2.
Mining Activities Mining also contributes to deforestation. The process of extracting materials and ores like gold, coal, diamond or stones from beneath the earth surface demand the removal of the entire forest cover. In addition to mining, forest cover is cleared to construct roads to enable heavy machinery and trucks to access the mining areas.
Forests provide a wide range of economic and social benefits for instance through employment, value generated from the processing and trade of forest products, and investments in the forest sector. Benefits also include the hosting and protection of sites and landscapes of high cultural, spiritual, or recreational value.
