Define "phytoremediation."

Phytoremediation is defined as the use of plants to extract, stabilize, or degrade contaminants in soil and water. This process takes advantage of the natural abilities of certain plants to absorb or breakdown harmful substances such as heavy metals or organic pollutants. By utilizing plants in this manner, phytoremediation provides an eco-friendly alternative to traditional remediation methods, which often involve chemical treatments or physical removal of contaminated soil.

While the other options discuss agricultural practices or soil management techniques, they do not address the specific use of plants to remediate contaminated environments. By focusing on the capabilities of vegetation to address pollution, phytoremediation presents a sustainable solution to managing contaminated sites effectively.
