Until Homo sapiens became the dominant life-form and initiated the Industrial Revolution, the waste removal achieved by the joint action of bacteria and fungi served nature quite well. Today, however, with over 5 billion people on earth, nature's system of decay is overwhelmed. People are generating so much waste matter that waste disposal has become one of the greatest problems on earth. Wastes are sources not only of pollution and ugliness but of disease.
In addition to the urgent need for improved methods of processing wastes as they are produced, there is a massive need for improved methods of waste-site remediation, that is, cleaning up existing, heavily polluted sites.
Early efforts toward remediation of waste sites relied on conventional technologies such as excavation, ...

Considerable research remains to be done if their potential is to be realized. The field of bioremediation by higher plants is so new that it is wide open for important and original research. One can only hope that this new frontier will attract the pioneers and builders who can expeditiously bring plants' cleanup potential to the service of humanity. vbcrlf
