Sir, - If supermarkets, shops and the Governments were really concerned about the environment, they would scrap plastic bags altogether, and put the 15p tax on each bag towards the cost of supplying cellophane bags instead. Cellophane, while having the advantage of being waterproof, and thus suitable for Irish weather conditions, is also biodegradable. - Yours, etc.,
Rynagh MacCarthy, Castleknock, Dublin 15.
