There are so many ways we have benefited from the chemical industry and you've named a number of them in your post. I think there is probably not one area of our lives that is not impacted by this industry. You mentioned the chemical industry and crops and how there are negative and positive impacts. The chemical composition of the soil, the topography, and the presence of living organisms determines the quality of soil. In general, soil contains 40-45% inorganic matter, 5% organic matter, 25% water, and 25% air.
Soil contamination occurs when human-made chemicals, such as hydrocarbons and heavy metals, find their way into the earth, altering the natural soil environment. Generally, soil contamination is cited as a consequence of non-organic farming practices, industrial activity and improper waste disposal.
Can you name other ways soil contamination occurs?
