Lab-Grown Meat: Key Concepts

Lab-grown meat, introduced in 2013, offers a sustainable alternative to traditional meat production. It requires fewer resources and has a lower environmental impact. The process involves harvesting stem cells from cows and culturing them to grow muscle tissue. Although lab-grown meat is currently more expensive than conventional meat, its price is decreasing as production methods improve. This innovation promises to be a more efficient way to meet the protein needs of the growing global population.
