The importance of the earth upon which we stand shouldn’t be underestimated. It fosters the fruits, vegetables and grains during their growth which we ultimately eat to sustain ourselves. Clearly, ensuring this soil is free from contamination is of paramount concern. With this in mind, a growing emphasis has been placed on soil remediation and treatment over the last decade or so. Whereas traditionally soil has been largely free of pollutants, the dramatic upsurge of industrialisation across the globe has led to greater contamination through the sewage, waste products and other unwanted side-effects of factories, businesses and homeowners. Meanwhile, agriculture has led to the widespread use of pesticides and fertilisers, which are often harmful for the health of the soil.
