1. Dear Mrinalini, Naturally

Dear Mrinalini,


Naturally occuring biomass in sewage is sufficient for its treatment. This is GOD's gift.


Use of genetically modified stuff claiming accelerated performance is neither needed nor safe because it can be another "biological warfare". Remember PL 480 programme of US in mid 1950s wherein they sowed the seeds of a thorny plant saying it will protect foodcrops from grazing by animals and today our wilderness is getting automatically and uncontrollable covered by these thorny bushes all over making it actually a menace to agriculture.
