Poland launches unusual ad in effort to grow birth rate

 The Polish government is urging its citizens to go forth and multiply like rabbits.
Sporting one of the lowest birth rates in Europe, Poland has put out a video through its health ministry praising rabbits for producing many offspring.
The spot shows rabbits munching on veggies while a rabbit ``narrator'' reveals the secret of their big families includes exercise, a healthy diet and little stress.
The brief appearance of a human couple enjoying a romantic picnic hints that a little romance might help, too.
