Sir,
I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.
The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.
So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.
Thanking you,
XYZ.
