Synopsis
David Bellamy begins his trip around the nitrogen cycle in the Surrey hospital where he languished as a child suffering from acute kidney failure. He ends it by juggling with dung and urine in a Dutch pig farm. In between he explains how nitrogen is essential to all forms of life, but warns that too much of it can kill. To avoid poisoning the earth, the water and ourselves, the nitrogen cycle - in the state it is in at the moment - must be restored to safe dimensions.
