How do you save a vanishing island? Well, Tamil Nadu has already saved one and is set to save another in the next four years in the Gulf of Mannar. The Gulf is the country’s first marine biosphere and has innumerable jewels that adorn it. The crown was a set of 23 islands that dot the southern coast of Tamil Nadu, between the holy town of Rameswaram and the pearl city Thoothukudi.
