Mr. Forbush and the Penguins Quote
Tringham: [in a flashback voiceover] The skuas say in effect to the penguins, 'We'll keep the other skuas off in return for a fair share of your eggs and chicks.' In this way nature ensures the survival of a sufficient number of penguin chicks. A providence no to be despised by the thinking scientist.
