Land pollution or the degradation of our soil by external pollutants is largely due to unsustainable agricultural practices, inadequate waste disposal (both hazardous and non-hazardous), mining (often called “mineral extraction”), illegal dumping and garbage. To reduce land pollution, it is important to take the initiative to inform others about the harmful effects of littering, buy organic products, especially organic cleaners, pesticides, insecticides and fertilizers, improve land fertility through reforestation, composting, and reducing and reusing waste products. Additionally, the mechanical method of controlling soil pollution includes the use of the contour retention system, the control of ravines and the creation of limits. In areas with excessive slope, making limits along the slope helps prevent erosion.
Furthermore, it is important to support renewable resources and conduct research and evaluation of the soil before using any new land. Companies can also reduce their environmental impact by using safer pesticides and fertilizers and reducing soil erosion and runoff through the use of smarter and more sustainable practices. Finally, if the results show that the reclaimed land is contaminated, any scheduled activities on the land must be suspended and the responsible body must take the necessary precautions not only to manage and mitigate risks, but also to prevent contamination of adjacent soils.
