The Phosphorus Cycle (04/07/1991)
This episode shows the importance of phosphorous in human chemistry (ADP and ATP) and how wasteful we are in our use of this vital resource.

The Sulphur Cycle (11/07/1991)
Sulphur's importance in the formation of proteins in living things makes it crucial that there is sulphur in the environment, however, our reliance on fossil fuels means that mankind plays a strong part in the acicdification of the world. This programme looks at that and the effects of volcanic activity.

The Human Race (18/07/1991)
This programme deals with the greatest threat to the natural world and the cycles which have been going on for millenia - us. Bellamy does not berate us too hard for what we do but does stress that to be deserving of the beautiful planet we inhabit we should take responsibility as a species and strive for sustainability in all things.
