Effects of Soil Pollution

1. ........................................................... : Considering how soil is the reason we are able to sustain

ourselves, the contamination of it has major consequences on our health. Crops and plants grown on

polluted soil absorb much of the pollution and then pass these on to us. This could explain the sudden

surge in small and terminal illnesses.

2. ........................................................... : The ecological balance of any system gets affected due to the

widespread contamination of the soil. Most plants are unable to adapt when the chemistry of the soil

changes so radically in a short period of time. Fungi and bacteria found in the soil that bind it together

begin to decline, which creates an additional problem of soil erosion.

3. ........................................................... : The toxic chemicals present in the soil can decrease soil fertility

and therefore decrease in the soil yield. The contaminated soil is then used to produce fruits and

vegetables which lacks quality nutrients and may contain some poisonous substance to cause serious

health problems in people consuming them.

4. ........................................................... : The emission of toxic and foul gases from landfills pollutes the

environment and causes serious effects on health of some people. The unpleasant smell causes

inconvenience to other people.

5. ........................................................... : The death of many soil organisms (e.g. earthworms) in the soil

can lead to alteration in soil structure. Apart from that, it could also force other predators to move to other

places in search of food
