Which of the following factors does NOT contribute to soil/land pollution?

Explanation:

Soil pollution occurs when harmful materials contaminate the ground, altering its physical, chemical, and biological properties. The primary factors contributing to soil pollution include:

Mining:

• Mining activities, including excavation, processing, and waste disposal, can leave behind contaminated soil with high levels of heavy metals and other pollutants.

Agricultural activities:

• The excessive use of fertilizers and pesticides disrupts the natural balance of soil microorganisms and beneficial insects.
• This dependence on chemicals ultimately weakens the land and reduces its productivity.
• Improper livestock waste handling can contaminate the soil with pathogens and excess nutrients, leading to degradation and threatening water quality.

Domestic wastes:

• Open dumping of waste is a common practice in many parts of the world, leading to the accumulation of waste and its release of harmful substances into the environment.
• Even in managed landfills, the risk of leakage of leachate and contamination of surrounding soil and water remains a concern.

Deforestation:

• Large-scale deforestation for agriculture, logging, and other purposes can lead to soil erosion, desertification, and land degradation.
• This destroys valuable ecosystems and reduces the land's capacity to absorb carbon dioxide, contributing to climate change.

Additional Information Eutrophication:

• The excessive enrichment of water bodies with nutrients, particularly nitrogen and phosphorus, is known as Eutrophication.
• This phenomenon, while natural to a certain extent, accelerates due to human activities, leading to detrimental consequences for water quality and infrastructure.
