The British academic and Assistant Director General of UNESCO Richard Hoggart explores the concepts of communication in his Reith lecture series entitled 'Only connect'.

In this lecture entitled 'Common Ground', Richard Hoggart evaluates the role of passing information to each other via a system of communication. He asks, now that we have developed at an almost unbelievable speed, what happens next? Are we really more in touch now than previously? How will new technologies bring us closer? Centralised mass societies are keen to show they understand the human scale but can human societies remember to interact with each other in a fundamentally kind and moral way?

The Vice-President of the Conservation Foundation in Washington, DC and renowned ecologist Sir Frank Fraser Darling explores the concept of Man's responsibility for his natural environment in his Reith series entitled 'Wilderness and Plenty'.

In his final lecture entitled 'Where Does Responsibility Lie?', Sir Fraser Darling argues that population is almost certain to increase but pollution does not necessarily need to. He argues that technology should use its own inventiveness to decontaminate the world, but asks who would be responsible for enforcing such a policy. Without all nations taking the ethical responsibility for the environment, he concludes, it will take many years for intellectually-led change to filter through and become concrete action plans.

He ponders whether rises in prosperity and population might just signal the decline of the habitable world.
