The resources of nature are under siege from anthropogenic activities
exacerbated by rapid global population growth. Wetlands are among the
most productive ecosystems but they are fast becoming the most
threatened habitats and the backlash of such a trend is catastrophic to
humanity. The preference of biological assessment over chemical
assessment is due to the the advantage that the former has in revealing
ecological integrity values of wetlands. Phytoremediation expecially
with Vetiveria zizanoides is promising for wetland reclamation and is
inferior to no other option. This pathway is promising, cheaper and
sustainable.
