13 Nov A video clip on alapuzha intra coastal water way nicely pictured deeply eutrophicated Canal using a Sony professional camera. Say five or so years ago chathopadhyaya of Cess had implemented a action research project to remove the water hayacynth and such stuff. Obviously tax money was there. I those days thought it was only window dressing. Remedies are physical removal etc. and not backed by science. Provides good feed stock to 24 hr news cycle. Nothing else. Sadly this is the way the science goes. Esoteric science is the goal in the lab and no solution search..solution will come over Internet or Dreamliner ..
