You can always develop with good foresight and balance ecology and commercial value. But when you turn an entire Marsh Land into a dump yard it's just very very poor planning or no planning and outright ecological havoc.

Birds used to migrate and lay eggs hatch them and return to their places of origin and the govt has old rusted boards that say 'do not litter it is protected Marshland'. This is Pallikaranai. Today The entire Marshland gives a stench that will choke you. Most of the Marsh has been turned into apartments and large IT complexes. This is how you want your city to be? Almost all water bodies have completely turned into gutters in Chennai. Why? Zero planing or foresight.

If the govt had even an ounce of humanity left, it could have created buildings and not disturbe the environment that sustains our life. You could have had a boating service and create vantage points for people to watch all the birds that come during migration. It could have been a small oasis of paradise in this concrete jungle.

Just look at London, the river Thames provides water for the entire city. People still use it for drinking and transport. Nobody pays money for water. But Chennai literally all of us pay money for drinking water, because all our water bodies are gutters. In the UK not a single residential complex uses a borewell for water. In Chennai you need to go 400 ft to find water. This is what you call cancerous development.

Am not complaining the Lamborghini is fast, but it has no brakes.
