Two different ways that our soil can become polluted are:
- Agricultural Practices: The use of pesticides, herbicides, insecticides, and chemical fertilizers in farming can contaminate the soil. These chemicals may remain in the soil for extended periods, disrupting the natural composition, reducing fertility, and potentially entering the food chain through contaminated crops. Heavy metals present in some fertilizers can also increase soil toxicity, posing risks to plant, animal, and human health.
- Industrial Activities and Waste Disposal: Industrial processes often release toxic substances such as heavy metals, solvents, and other chemicals into the environment. Improper disposal of industrial waste, leakage from landfills, and accidental spills can lead to soil contamination. These pollutants can persist in the soil for long periods, adversely affecting soil quality and ecosystems.
These types of pollution not only degrade soil health but also affect groundwater, plant and animal life, and human health through exposure and the food chain.
