To the editors,

I would encourage a follow-up to Harold Henderson's article of 20 August 2004, "The Bad Earth," that explores phytoremediation and phytoextraction, the use of plants that fix heavy metals and toxins as a means of contaminant cleanup. The same reasons he enumerated for not eating root or leaf plants in lead-compromised soils (i.e. uptake and buildup of toxins) provide a transition into a discussion of green remediation or abatement techniques (e.g. using the correct leaf and root plants to clean the soil over several seasons). While his recommendations for dealing with lead in soil were accurate and reasonable, a responsible follow-up by the Reader would be to provide further recommendations for making the soil useful and healthy again and not just something to be avoided.
