Which of the following is not a possible consequence of surface mining?
a. increased pollution
b. improved ecosystem health
c. destruction of flora and fauna
d. erosion of soil

Option B, improved ecosystem health, is the right answer.

The process of extracting minerals from the earth's surface is known as surface mining.  The open-pit mining, quarrying and strip mining are the three most common varieties of surface mining. Mining has affected the environment and living population in adverse ways. The effect of mining on the environment includes soil erosion, loss of biodiversity, the creation of sinkholes, contamination of groundwater and soil by the chemicals emission during the process. As mining effects, the environment negatively “improved ecosystem" cannot be a consequence of surface mining.
