The most common causes of soil pollution include industrial waste or by-products. The root cause of soil pollution is often one of the following: Agriculture (excessive/improper use of pesticides) Excessive industrial activity. Soils polluted by acid rain have an impact on plants by disrupting the soil chemistry and reducing the plant's ability to take up nutrients and undergo photosynthesis. Pesticides and fertilizers are full of chemicals that are not produced in nature and cannot be broken down by it. ; Deforestation and soil erosion: Forests are home to more than 80% of terrestrial biodiversity and are a refuge for many animal and plant species.In this sense, deforestation is a catastrophe both for man and for other living beings. Additionally, construction dust may easily spread around through the air and is especially dangerous because of its lower particle size (less than 10 microns). ~ Industrial wastes such as harmful gases and chemicals, agricultural pesticides, fertilizers and insecticides are the most common causes of soil pollution.
