Soil is important to human. People use soil to develop agriculture and rely on soil-grown crops to survive. However, due to the large number of mining companies to develop the mining industry, resulting in serious soil pollution. Chemicals from mining minerals tend to create biochemical reactions when exposed to air. The resulting new material will slowly seep into the soil. As a result, over time, these chemicals accumulate more and more. The accumulated chemicals eventually form a variety of toxins hat harm human health. Farmers grow crops on the contaminated soil. During the growth of crops, nutrients are drawn from the soil. These toxins are absorbed through the roots of the plant. When the crops are ripe, they are sold to the market and end up being eaten by people. These toxins are absorbed by human body and threaten their health.
