Polluted soil refers to land that has been contaminated by harmful substances, making it unsafe for plants, animals, and humans. This pollution can result from various sources, including industrial waste, agricultural chemicals, and improper disposal of hazardous materials. When soil is polluted, it can lose its nutrients and ability to support healthy ecosystems. The effects of polluted soil can be severe, leading to reduced crop yields and health risks for those consuming contaminated food. Remediation efforts, such as bioremediation and soil washing, are often necessary to restore the soil's health and safety. Addressing soil pollution is crucial for sustainable agriculture and environmental protection.
