Soil pollution is caused by industrial waste that deprives soil from essential nutrients. The redundant, ever increasing use of chemicals such as pesticides, herbicides, insecticides and fertilizers is one of the main factors causing soil pollution by increasing its salinity making it imperfect for crop bearing and adversely affecting the microorganisms present in the soil, causing the soil to lose its fertility and resulting in the loss of minerals present in the soil, thus causing soil pollution and killing off more than just the intended pest.
Soil pollution occurs when soil contains chemicals that are toxic or otherwise dangerous for humans and other living things. Soil pollution can cause organ damage. The presence of heavy metals in soil in toxic amounts can cause irreversible developmental damage in children, according to the website Tropical Rainforest Animals. Although lead and mercury may be found naturally in soil, high concentrations of either metal may cause damage to the developing brains of young children, which in turn may lead to neurological problems. Humans of any age may also suffer kidney or liver damage from exposure to excessive mercury in soil.
