Eco problems of Kochi

Kochi is facing Eco-problems.Last weeks newspapers reports that oxygen level under sea water is decreasing.This phenomenon "Anorexia'' is regular here.The water quantity comes to sea through river is law than before due to large number of dams in river,lack of dredging in river mouth are the reasons for this phenomenon.This will effect bio system.
Islands,lakes&farms are miss using in the name of development.Thanthinni island for knowledge&Valanthakkadu for Sobha High City.The mangrove will vanish for ever.The mangrove are very use full in preventing tsunami.There are lots of fish &birds in that area.All that will be disturbed for development.
Developments are must but Eco-friendly.
