Crops and plants grown onpolluted soil absorb much of the pollution and then pass these on to us. This could explain the suddensurge in small and terminal illnesses.2. ........................................................... : The ecological balance of any system gets affected due to thewidespread contamination of the soil.

Fungi and bacteria found in the soil that bind it togetherbegin to decline, which creates an additional problem of soil erosion.3. ........................................................... : The toxic chemicals present in the soil can decrease soil fertilityand therefore decrease in the soil yield. The contaminated soil is then used to produce fruits andWEEK 2vegetables which lacks quality nutrients and may contain some poisonous substance to cause serioushealth problems in people consuming them.4. ........................................................... : The emission of toxic and foul gases from landfills pollutes theenvironment and causes serious effects on health of some people.
