Globally, more than 150 companies are focusing on meat from cells, not only chicken but pork, lamb, fish and beef, which scientists say has the biggest impact on the environment.

The chicken was grown from a cell taken from an egg and put in a bioreactor to multiply. The company's CEO, Josh Tetrick, said lab-grown meat could cut the carbon footprint of farming.

The chicken doesn't come from a bird, but is instead grown from chicken cells. Good Meat, the California-based company supplying the lab-grown poultry, calls it cultivated chicken.
