The primary cause of soil pollution is contamination from chemicals, such as those commonly found in pesticides. Overexposure of land to synthetic fertilizers as well as oil spillages are also causes of serious soil pollution. Soil pollution is usually the result of unhealthy methods of soil management and/or harmful methods of irrigation.
Consequences of Land Pollution
Land pollution can affect wildlife, plants, and humans in a number of ways, such as:
- Cause problems in the respiratory system
- Cause problems on the skin
- Lead to birth defects
- Cause various kinds of cancers
The toxic materials that pollute the soil can get into the human body directly by:
- Coming into contact with the skin.
- Being washed into water sources like reservoirs and rivers.
- Eating fruits and vegetables that have been grown in polluted soil.
- Breathing in polluted dust or particles.
Preventing Land Pollution
- People should be educated and made aware about the harmful effects of littering.
- Items used for domestic purposes should be reused, recycled or properly disposed of.
