Answer;
B. improved ecosystem health
Explanation;
-Surface mining is a method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.
-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.The environmental effects of surface mining include;
An improved ecosystem cannot be a possible consequence of surface mining.
Further Explanation:
Surface mining is a process of extraction of mineral beneath the surface of earth or from the earth's surface. This process is used to recover the gravel, coal, metal, iron, sand, and stones. There five different kinds of surface mining with a particular change depend upon the mineral that is being extracted from the earth’s surface. The air gets contaminated with carbon monoxide, hydrocarbons, sulfur oxide, nitrogen oxide, and ground-level ozone during the process of surface mining.
The mining process loses the soil particle, which is responsible for large scale erosion. These eroded particles, when scatters in the ecosystem, cause destruction of fauna and flora. Though the mining process releases harmful particles in the environment and has many negative consequences, thus, it cannot be taken as a factor that improves the ecosystem.
