Scientists say the world's first test-tube hamburger, made from meat produced from the stem cells of a cow, will be ready this fall.
Dutch scientist Mark Post told a major world science conference Sunday that his aim is to invent an efficient way to produce skeletal muscle tissue in a laboratory that exactly mimics meat, and eventually replace the entire meat-animal industry.
Post and other researchers hope they can mass produce the artificial beef to help meet the growing demand.
They say it will be better for the environment because the current methods of producing food require land, water, and other resources.
The global demand for meat is expected to rise by 60 percent by 2050, American scientist Nicholas Genovese, who organized the symposium, told Discovery News.
"But the majority of earth's pasture lands are already in use," he said, so conventional livestock producers can only meet the booming demand by further expansion into nature.
The beef will be expensive at first but scientists expect the cost to go down in time.
