The world's population is continuing to increase and an ever greater proportion want to eat meat. To meet that demand farmers will need to use more energy, water and land - and the consequent increase in greenhouse gas emission will be substantial.

The plan for lab-grown burgers has won support from some animal welfare and vegetarian groups, who feel it addresses their concerns about animal suffering.

But critics say technological fixes, whether it is lab-grown meat or GM crops address the symptoms rather than the causes of world hunger. What is needed, they say, are policies that enable more farmers to produce more food more efficiently and to distribute it more equitably.

And then of course there is the taste. Even those behind the stem cell project agree that the meat grown will never taste as good as that from an animal. But as prices rise, environmental pressures grow and concerns over animal welfare increase, they argue their approach is the only ethical and pragmatic way forward.
