BBC World Service - The Big Idea, A world without livestock?

Can you make meat without animal flesh? Professor Pat Brown is trying to do just that.

What is the biggest cause of climate change?  According to biomedical researcher Pat Brown it’s an extremely inefficient technology – aka cows.  Maintaining livestock is hugely expensive.  It produces greenhouse gases.  And it takes up much of the land we use on the planet.   So what’s the solution?   Professor Brown believes it’s the creation of a new meat – meat which is made without animal flesh.
