Presented by Fergus Keeling The death of a young golden eagle on the west coast of Scotland has disturbing implications for all marine and coastal wildlife around Britain's shores: the bird's body was full of pesticides and industrial waste chemicals. Where do the chemicals come from? How do they accumulate in the food chain? Will we see an alarming increase in disorders and deaths as the poisons build up in the bodies of the top predators, including man?
