Save the Inlet

Last night we found out that sediment is entering the Inlet 4 times faster than it is being flushed out- this means it will soon be impossible to go sailing, fishing, or just admire the jewel in Porirua City's crown ! Do people really care about this or are we just going to keep driving 40 tonne trucks around the Inlet's roads day and night, plus thousands of cars a day until one day we notice the view has changed somewhat and there's a pungent smell coming where once migrating birds gathered before their mass departures to other shores.
What kind of action are you willing to take to save the Inlet ?
