New mountains are coming up in the middle of Mumbai city! The growth of these 'mountains' is quite apparent along patches of the Western Express Highway, and rail-tracks along Mahim and Andheri.
The mountains are unique in their formation because they are not made up of any kind of rock or stone. And this may be the very first time in the history of our planet that such mountains are coming up in the heart of a metropolis.
Also, these mountains are entirely man-made...they are formed of Human Shit.
