the negative effects of mining in wast A frica does not include?

Step 1: Analyze the question The question uses "does NOT include," so we are looking for the option that is not a negative effect of mining. Three options will be harmful effects, and one will be a positive or neutral outcome.

Step 2: Explain the concept Mining (for example, gold in Ghana, tin in Nigeria, bauxite in Guinea, and oil extraction in the Niger Delta) involves clearing land, digging pits, and processing minerals with chemicals. This causes environmental damage such as:

• Land degradation (the soil is stripped, leaving pits and wasteland)
• Destruction of farmlands (land is taken over or ruined by excavation)
• Pollution of water bodies (chemicals such as mercury and cyanide, and waste, drain into rivers)
• Deforestation (trees are cut down to make way for mining)

Step 3: Check each option

• A. Reafforestation in rural communities means replanting trees. Mining does not cause this. It causes the opposite, which is deforestation. So this is not a negative effect of mining.
• B. Land degradation is a negative effect of mining.
• C. Destruction of farmlands is a negative effect of mining.
• D. Pollution of water bodies is a negative effect of mining.

Step 4: Answer The option that is NOT a negative effect of mining is A. Reafforestation in rural communities.

Exam tip: In "does not include" or "except" questions, look for the option that is the opposite of the pattern. Here, three options describe damage, while "reafforestation" describes restoration. Also watch out for the word pair deforestation (harmful, caused by mining) versus reafforestation (beneficial, the opposite).
