What the story is about:
The little swallow cannot avoid the dark, dirty cloud, fortunately a boy finds her lying unconscious on
the ground. He takes her on his bike to the countryside. The bike-basket is stuffed with the soft cotton which he took out of his own jacket, when he arrives in a nice spot he attaches the basket with the swallow in it to a large pine-tree. Quite a luxurious nest! Human beings are the cause of all the pollution on earth, but after all the swallow was rescued by a small human being....
