This week's programme in the series on man and science today.

Every day there are 135,000 more mouths to feed. Can they be fed? Scientists are optimistic. Using techniques ranging from the genetic manipulation of wheat to the psychological manipulation of sheep, they are convinced that world food production could perhaps be trebled.
They can offer synthetic proteins and improved plants while suggesting the domestication of new animals, farming fish or even fermenting cassava ... yet half the world still starves. Why?

"I've been in countries where the technical solutions were well known, but sheer political inertia, the deadweight of tradition, ignorance, and often lack of leadership have prevented anything happening" (Dr Pereira, East Mailing Research Station).
