Anywhere along the coast in India, there will be trash. It always amazes me in beach towns and resorts in Asia how many of the local restaurants and bars and even the hotels actively pollute the resource that brings in the tourists and therefore, the money. But in cities, there is no escaping it. The water, waves, sand, and beaches of the metropolises and their suburbia are quite often an unpleasant color, and guide books will warn against really any exposure. The occasional trash in the waves, I am used to, sadly, but general health and safety warnings against getting in the ocean at all are pretty frightening.
