which of the following IS NOT an effect of mining

soil pollution
water pollution
destruction of forests
preservation of forests

preservation of forests

The effect of mining that is NOT associated with the process is preservation of forests. Mining usually involves clearing large areas of forests for exploration, extraction, and infrastructure development. This leads to deforestation and the destruction of habitats for various plants and animals. Consequently, soil pollution and water pollution can occur as a result of mining activities, due to the release of chemicals and toxic substances into the environment.

To determine which of the following is NOT an effect of mining, we can analyze the options one by one.

1. Soil pollution: Mining operations can result in soil pollution due to the excavation and disturbance of land. This can introduce harmful chemicals and heavy metals into the soil, contaminating it and potentially affecting agriculture and ecosystem health.

2. Water pollution: Mining activities can lead to water pollution through the discharge of toxic substances into nearby water bodies. The extraction and processing of minerals often involve chemicals that can contaminate rivers, lakes, and groundwater.

3. Destruction of forests: Deforestation is a common consequence of mining activities. Forests are cleared to make way for mining operations, which destroys habitats, disrupts ecosystems, and can contribute to climate change.

4. Preservation of forests: This is the option that does NOT align with the effects of mining. Mining itself does not involve the preservation of forests. On the contrary, it often leads to the destruction of forests, as mentioned in option 3.

Therefore, the correct answer is "preservation of forests," as it contradicts the typical effects of mining.
