Changes in temperature6. Changes in soil structureEffects of Soil Pollution1. ........................................................... : Considering how soil is the reason we are able to sustainourselves, the contamination of it has major consequences on our health. 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. Most plants are unable to adapt when the chemistry of the soilchanges so radically in a short period of time. 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. The unpleasant smell causesinconvenience to other people.5. ........................................................... : The death of many soil organisms (e.g. earthworms) in the soilcan lead to alteration in soil structure. Apart from that, it could also force other predators to move to otherplaces in search of food
