As we have more cruise ships visiting our shores, it also means more dumping of raw sewage into our oceans and the result is for us to pay…tar balls on our beaches. The sea invariable throws back what we throw in!
Oily tar balls have surfaced again on Miramar beach and some stretches of North Goa coast from Anjunato Keri, as the sticky matter on the shore slightly troubled tourists enjoying a walk or a dip in the sea.
A long stretch of the beach from Miramar to Caranzalem towards the south was tarred black with a filmy deposition of the tar balls. Though big blobs were not seen, it left stains on the soles of the feet and the skin.
Sources said the tar ball problem was mild and not a major problem, as it occurs during pre-monsoon and the rainy season in all intensity. “There are no big patches of the tar balls so far,” a tourism stakeholder said.
The churning of currents on the high seas gives rise to the tar ball phenomenon, especially during May-October season, fouling the water and the beach ambience. The deposition of oily hydro-carbons was first being noticed in 1970s, but over the last few decades, the incidence has been growing due to increased movement of ships in marine waters.
