Scientists unveiled the world's first lab-grown beef burger, serving it up to volunteers in London in what they hope is the start of a food revolution.

They then grew this into small strands of meat, 20,000 of which were required to make the burger.

Proponents of test tube meat cite a variety of reasons for why it is worth supporting, from animal
