Which of the following is not a method for addressing soil contamination? a. excavate and dispose of the soil. b. use microbes to digest the contaminants. c. use heat to force the contaminants into the gas phase and out of the soil. d. none of the above

The correct answer is D. None of the above

Explanation:

Soil contamination occurs as the soil is altered by non-natural substances or agents such as chemicals, metals, pesticides or waste. This usually has a negative effect on ecosystems and might represent a risk for health and life. In terms of approaches to address, reduce or eliminate soil contamination, methods that are commonly used include excavating and removing the soil that has been contaminated, extracting contaminants through heat making them become a gas, and using plants, fungus, microbes or other organisms to remove and diggest specific contaminants.

This means, all of the options given are methods for addressing soil contamination and thus, the correct answer is none of the above because all of these methods are a way of addressing soil contamination.

scientific consensus is : a general agreement among scientists about a scientific idea.

even though consensus implied general agreement, it doesn't mean unanimity. for example, scientists generally agree that meteor caused dinosaur's extinction. though this may not be proven yet, but it considered a consensus.
