Answer:
Causes of Soil Contamination
Soil pollution is mostly caused by mindless human activities such as:
Industrial waste
Industries are by far the worst polluters of the soil with all the chemicals they release into the environment be it in liquid or solid form.
Deforestation
Clearing of trees leaves soil exposed to the elements so they are easily carried away by soil erosion. This leaves land barren and incapable of supporting vegetation.
Excessive use of fertilisers and pesticides
The increased demand for food has forced farmers to use fertilisers and pesticides that release nothing but toxins into the soil, killing useful microorganisms that are important in plant growth.
Garbage pollution
Garbage that cannot be recycled is disposed of carelessly and this is not only an eyesore but pollutes the land. Some of this waste can literally take thousands of years to decompose!
